run402-mcp

This is the backend Kychee's open products run on. We needed a layer an agent can drive end to end, with room for whatever each app turns out to need, and nothing off the shelf had all of it, so we built it and opened it the same way we open the apps: this repo holds the agent surfaces (MIT), run402-core holds the full backend (Apache-2.0), and kysigned is the first product running on it.

One call to run402 gives an agent a full Postgres database, REST API, user auth, content-addressed file storage, static site hosting, serverless functions, and image generation, paid with x402 USDC on Base (or Stripe credits). The prototype tier is free on testnet.

Run402 is agent-first because agents are first-class participants, not because people disappear. A person or agent acts through its own Run402 principal and authenticator, and its actions remain attributable. Identity answers who acted; memberships, roles, grants, delegates, freshness, and spend policy determine what that principal may do.

An autonomous agent may remain the legitimate owner of the org-of-one it creates. People may join through explicit co-ownership. Agents entering somebody else's organization receive bounded authority instead of borrowing a human account. Different keys. Equal standing. Explicit authority.

This monorepo ships every surface an agent can pick up:

These interfaces share a single typed kernel where appropriate: @run402/sdk. MCP tools, CLI subcommands, and OpenClaw scripts are thin shims over SDK calls. @run402/functions is the in-function helper that runs inside deployed code; the npm package on the registry is the artifact Cloud bundles. @run402/astro layers the SDK and functions runtime into Astro's build and SSR flow. Pick whichever interface fits your runtime.

30-second start

npm install -g run402@latest
run402 up --name my-app -y                           # bootstrap allowance/tier/project/link, then deploy manifest
run402 up verify                                     # rerun app HTTP verification without deploying
run402 up --verify                                   # deploy, then wait for gateway/edge coherence
run402 subdomains claim my-app                       # → https://my-app.run402.com

That's a real Postgres database + a deployed static site, paid for autonomously with testnet USDC.

Buy from any x402 seller with the same allowance and a default $0.10 ceiling:

run402 pay https://seller.example/translate --method POST \
  --body '{"text":"hello"}' --max-usd 0.05 \
  --idempotency-key translation:1 --require-receipt

The SDK equivalent is r.pay.fetch(url, init, { maxUsdMicros, idempotencyKey, requireReceipt }); MCP callers use pay_url with require_receipt: true. All three return the same x402-commerce-result.v1 settlement, movement/replay, delivery, offer, merchant-receipt, signer-relationship, policy, and raw-evidence fields and pass unpriced URLs through with payment: null. Requiring a receipt rejects before payment when no wallet-rooted offer is eligible. If a promised receipt cannot be verified after settlement, PaymentPolicyError retains the upstream response and paid result and tells the caller to reconcile—never to pay again. For a trusted Run402 PAYMENT_INTENT_PENDING, all three surfaces prescribe one recovery path: wait for Retry-After, then repeat the same request with the same payer and key. Never replace the key. The SDK and MCP can also re-present an ambiguous proof while their process remains alive; custom/arbitrary sellers remain ambiguous and require reconciliation.

Prefer run402 up when a repo has run402.deploy.json or app.json. The CLI stays a thin shim over the Node SDK action runner (r.actions.run(...) / r.up(...)): it validates the manifest first, then recursively performs only the missing prerequisites. Project resolution is --project, .run402/project.json, manifest project_id, approved creation from --name, then approved active-project fallback. --name is project creation/link metadata only; it is not part of the deploy manifest and never renames an existing project. Use --check for local validation and --plan for gateway-reviewed intent before applying.

If an app manifest defines verify.http[], run402 up verifies those URLs after deploy. Fresh run402 edge sentinel misses are reported as propagation_pending rather than permanent failures while the binding is still converging; tune that wait with --propagation-budget-s (default 120) or return immediately with --no-propagation-wait. run402 up verify reruns the same HTTP checks without uploading, deploying, creating projects, or mutating resources.

The CLI checks for newer run402 releases opportunistically and fail-open. Success stdout stays the command result; stale-version notices are advisory JSON on stderr, or cli.update_available NDJSON events in --json-stream. run402 doctor --refresh is the explicit live npm check and reports the install context plus the safest upgrade command for local, global, or ephemeral installs.

Typed deploy configs use the same commands. Executable configs are trusted local code, so v1 only runs them when passed explicitly:

run402 up --manifest run402.deploy.ts --check
run402 up --manifest run402.deploy.ts --plan
run402 up --manifest run402.deploy.ts --require-plan plan_...

--check and --print-spec are local-only. --plan asks the gateway for a reviewed plan with plan_id, plan_fingerprint, warnings, diff, and one next action. --require-plan reapplies only if the normalized spec and reviewed gateway facts still match.

import { defineConfig, dir, nodeFunction, sqlFile } from "@run402/sdk/config";

export default defineConfig(({ env }) => ({
  project: env.required("RUN402_PROJECT_ID"),
  database: { migrations: [sqlFile("db/001_init.sql")] },
  site: { replace: dir("dist"), public_paths: { mode: "implicit" } },
  functions: { replace: { api: nodeFunction("dist/functions/api.js") } },
  secrets: { require: ["OPENAI_API_KEY"] },
}));

Helpers normalize to the same ReleaseSpec as JSON manifests. dir() walks deterministically and rejects unsafe files unless explicitly allowed, sqlFile() derives the migration id from the filename unless supplied, and nodeFunction() currently expects JavaScript output; point TypeScript functions at built .js files.

The patterns

Paste-and-go assets: content-addressed URLs with SRI

assets.put() returns an AssetRef whose scriptTag() / linkTag() / imgTag() emitters produce HTML with the URL, the SRI integrity hash, and modern best-practice attributes (defer, loading="lazy", decoding="async", crossorigin) already wired. The URL is content-addressed (pr-<public_id>.run402.com/_blob/<key>-<8hex>.<ext>), served through the v1.33 CDN, and never needs invalidation:

import { run402 } from "@run402/sdk/node";
const r = run402();
const p = await r.project(projectId);

const logo  = await p.assets.put("logo.png", { bytes: pngBytes });
const app   = await p.assets.put("app.js",   { content: jsSource });
const style = await p.assets.put("app.css",  { content: css });

const html = `
<!doctype html>
<html>
  <head>${style.linkTag()}${app.scriptTag({ type: "module" })}</head>
  <body>${logo.imgTag("Company logo")}</body>
</html>
`;

Binary files must enter the SDK as bytes. In Node, use readFile(path) without an encoding; in browsers, use File.arrayBuffer(). Never read PNG, WASM, fonts, audio, video, archives, or other binary formats as UTF-8 and then hash or re-encode the resulting string: CAS can verify only the bytes it receives. The SDK rejects string sources for known binary keys/MIME types with BINARY_CONTENT_REQUIRES_BYTES before making a request. Directory helpers such as fileSetFromDir, dir, and assets.uploadDir are byte-safe by construction.

immutable: true is the default: the SDK computes the SHA-256 client-side, the gateway returns a content-hashed URL, and the browser refuses execution on byte mismatch. No cache-invalidation choreography, no waiting, no integrity-attribute construction.

Dark-by-default tables + the expose manifest

Tables you create are unreachable via /rest/v1/* until you declare them in a manifest. That closes the "agent created a table, forgot to set RLS, data leaked" footgun. The manifest is convergent: applying it twice is a no-op; items removed between applies have their policies, grants, triggers, and views dropped.

cat > manifest.json <<'EOF'
{
  "$schema": "https://run402.com/schemas/manifest.v1.json",
  "version": "1",
  "tables": [
    { "name": "items",  "expose": true,  "policy": "user_owns_rows",
      "owner_column": "user_id", "force_owner_on_insert": true },
    { "name": "audit",  "expose": false }
  ],
  "views": [
    { "name": "leaderboard", "base": "items", "select": ["user_id", "score"], "expose": true }
  ],
  "rpcs": [
    { "name": "compute_streak", "signature": "(user_id uuid)", "grant_to": ["authenticated"] }
  ]
}
EOF

run402 projects validate-expose <project_id> --file manifest.json
run402 projects apply-expose    <project_id> --file manifest.json
run402 projects get-expose   <project_id>

Built-in policies: user_owns_rows (rows where owner_column = auth.uid(); with force_owner_on_insert: true a BEFORE INSERT trigger sets it), public_read_authenticated_write (anyone reads, any authenticated user writes), public_read_write_UNRESTRICTED (fully open; requires i_understand_this_is_unrestricted: true), and custom (escape hatch: your own CREATE POLICY SQL).

Use run402 projects validate-expose or the MCP validate_manifest tool for a non-mutating feedback loop before applying. Optional migration SQL is used only to check manifest references; it is not executed as a PostgreSQL dry run, and this does not validate deploy manifests.

Auth-as-SDLC: put the same JSON under database.expose in your v2 ReleaseSpec. The gateway validates it against your migration SQL during deploy and rejects mismatches with a structured errors array listing every violation.

Slick deploys: deployDir + plan/commit + progress

deployDir walks a local directory, hashes every file client-side, asks the gateway which bytes it doesn't already have, and PUTs only those. Re-deploying an unchanged tree returns immediately with bytes_uploaded: 0.

import { run402 } from "@run402/sdk/node";

const r = run402();
const { url, bytes_uploaded, bytes_total } = await r.sites.deployDir({
  project: projectId,
  dir: "./dist",
  onEvent: (e) => process.stderr.write(JSON.stringify(e) + "\n"),
});

Progress events stream over onEvent (or stderr from the CLI) as unified DeployEvent JSON objects from the v2 deploy primitive.

CLI:

run402 sites deploy-dir ./dist --project prj_… > result.json 2> events.log

Same-origin web routes: static site + function ingress

Apply-v1 routes and static public paths are release resources: they activate atomically with the site, functions, migrations, secrets, and subdomains in the same deploy apply. Release static asset paths such as events.html are distinct from browser-visible public static paths such as /events. Use site.public_paths for ordinary clean static URLs; keep routes for function ingress and exact, method-aware static aliases.

{
  "project_id": "prj_...",
  "site": {
    "replace": {
      "index.html": { "data": "<!doctype html><main id='app'></main><script>fetch('/api/hello')</script>" },
      "events.html": { "data": "<!doctype html><h1>Events</h1>" }
    },
    "public_paths": {
      "mode": "explicit",
      "replace": {
        "/events": { "asset": "events.html", "cache_class": "html" }
      }
    }
  },
  "functions": {
    "replace": {
      "api": {
        "runtime": "node22",
        "source": {
          "data": "export default async function handler(req) { const url = new URL(req.url); return Response.json({ ok: true, path: url.pathname }); }"
        }
      },
      "login": {
        "runtime": "node22",
        "source": { "data": "export default async function handler(req) { return Response.json({ ok: true }); }" }
      }
    }
  },
  "routes": {
    "replace": [
      { "pattern": "/api/*", "methods": ["GET", "POST", "OPTIONS"], "target": { "type": "function", "name": "api" } },
      { "pattern": "/login", "methods": ["POST"], "target": { "type": "function", "name": "login" } }
    ]
  }
}

site.public_paths.mode: "explicit" means only the complete public_paths.replace table is directly reachable as static URLs. In the example, /events serves the release asset events.html, while /events.html is not public unless separately declared. mode: "implicit" restores filename-derived public reachability and can widen access, so review gateway warnings before confirming it.

Omit routes or pass routes: null to carry forward base routes. Use routes: { "replace": [] } to clear the route table. Route entries are an ordered replace list, not a path-keyed map. Function targets use { "type": "function", "name": "<materialized function name>" }. Static route targets use exact patterns only, methods ["GET"] or ["GET","HEAD"], and { "pattern": "/events", "methods": ["GET","HEAD"], "target": { "type": "static", "file": "events.html" } } where file is a release static asset path, not a public path, URL, CAS hash, rewrite, or redirect. Use static route targets for method-aware aliases such as static GET /login plus function POST /login; in explicit public path mode the backing asset can stay private by filename. Direct /functions/v1/:name calls remain API-key protected; browser-routed paths are public same-origin ingress.

Function routes can charge a fixed tenant x402 price before the handler runs by adding pricing: { "mode": "always", "amount_usd_micros": 250000, "pay_to": "org_default_payout" } to the route entry. 250000 is $0.25 per matching action. The portable ReleaseSpec contract also accepts receipt: "on_fulfillment" on a priced function route; a compatible host then requires the function to return payment.fulfilled(response) before it authors a receipt. Run402-hosted advertising remains gated off until the standard delegated-signer carrier is available—receipt intent never silently downgrades. Omit networks for production mainnet only; include "testnet" explicitly for testnet acceptance. Static aliases cannot be priced, direct function invocation is not monetized, and service/admin keys do not bypass a priced browser route. The owning org must have a resolvable payout wallet: set it with r.org(orgId).setPayoutWallet({ walletAddress }), run402 org payout-wallet <org_id> <wallet_address>, or MCP set_org_payout_wallet. Conditional credit systems should expose one fixed-price route such as POST /api/credits, then keep the rest of the app behind unpriced routes and app-local authorization.

Matching is exact or final-prefix-wildcard only. /admin and /admin/ are exact trailing-slash equivalents; /admin/* matches children but not /admin, /admin/, /admin.css, or /administrator, so deploy both /admin and /admin/* for a routed section root. Query strings are ignored for matching and preserved in the handler's full public req.url. Exact routes beat prefix routes; longest prefix wins; method-compatible dynamic routes beat static assets. A POST /login route can coexist with static GET /login HTML. Unsafe method mismatch returns 405, and matched dynamic route failures fail closed instead of falling back to static files.

Routed functions use the Node 22 Fetch Request -> Response contract: export default async function handler(req) { ... }. req.method is the browser method, and req.url is the full public URL on managed subdomains, deployment hosts, and verified custom domains. Derive OAuth callbacks from it, for example new URL("/admin/oauth/google/callback", new URL(req.url).origin). Append multiple cookies with headers.append("Set-Cookie", value); redirects, cookies, and query strings are preserved. On priced routes, import getRoutedPaymentContext from @run402/functions, read const paymentContext = getRoutedPaymentContext(req), and key app-side idempotency by paymentContext.paymentId. For a receipt-enabled route, return payment.fulfilled(response) only after the response represents completed delivery; the helper fails closed outside a settled, current, receipt-enabled routed invocation. The context helper reads gateway-confirmed x-run402-payment-* headers and returns null for unpriced or direct calls. The raw run402.routed_http.v1 envelope is internal; do not write route handlers against it.

Recipe: static home page + SPA shell. A SPA site ships index.html as the shell serving every unmatched route (match spa_fallback), so by default GET / serves the shell too. To serve a real static home page at / while keeping the shell for app routes, ship home.html at the site root alongside index.html and add an exact root static route alias: "routes": { "replace": [ { "pattern": "/", "target": { "type": "static", "file": "home.html" } } ] }. Route matching runs before all static resolution (including the implicit / -> index.html root mapping), and SPA-fallback derivation is independent of the route table, so GET / serves home.html (route_static_alias), unmatched app routes such as /dashboard still serve the shell (spa_fallback), and named static pages keep serving unchanged (static_exact). Expect two non-blocking plan lints: STATIC_ALIAS_SHADOWS_STATIC_PATH (warn: the alias overrides what / would otherwise serve; accurate and expected here) and STATIC_ALIAS_DUPLICATE_CANONICAL_URL (info: /home.html stays directly reachable in implicit public-path mode; add <link rel="canonical"> to home.html if duplicate-content SEO matters). Omitting routes on later deploys carries the alias forward; routes.replace is total, so a pipeline that sends it must include the alias every time. Verify with run402 deploy resolve --url https://<your-site>/ --method GET or deploy_diagnose_url and confirm match: "route_static_alias" with target_file: "home.html".

Avoid routing every static file, broad method lists by default, wildcard static route targets, leading-slash static files, directory shorthand, and one-static-route-target-per-page tables that exhaust route limits. Also watch wildcard function routes that shadow direct public static paths. Warning codes to handle include STATIC_ALIAS_SHADOWS_STATIC_PATH, STATIC_ALIAS_RELATIVE_ASSET_RISK, STATIC_ALIAS_DUPLICATE_CANONICAL_URL, STATIC_ALIAS_EXTENSIONLESS_NON_HTML, and STATIC_ALIAS_TABLE_NEAR_LIMIT; inspect active routes, static_public_paths, and resolve diagnostics to distinguish the route pattern from the backing asset_path.

Diagnose public URLs with the URL-first CLI or MCP/SDK equivalents:

run402 deploy diagnose --project prj_123 https://example.com/events --method GET
run402 deploy resolve --project prj_123 --url https://example.com/events?utm=x#hero --method GET
run402 deploy resolve --project prj_123 --host example.com --path /events --method GET

deploy_diagnose_url and r.project(id).apply.resolve({ url, method: "GET" }) return would_serve, diagnostic_status, match, normalized request data, warnings, full resolution JSON, edge_propagation, and next steps. When returned, asset_path, reachability_authority, and direct explain which release asset backs the public URL and whether reachability came from implicit file-path mode, explicit site.public_paths, or a route-only static alias. Stable-host diagnostics may also include authorization_result, cas_object (sha256, exists, expected_size, actual_size), hostname-specific response_variant, route/static fields such as allow, route_pattern, target_type, target_name, and target_file, and edge_propagation (settled, propagating, or sync_pending). Known match literals are host_missing, manifest_missing, active_release_missing, unsupported_manifest_version, path_error, none, static_exact, static_index, spa_fallback, spa_fallback_missing, route_function, route_static_alias, and route_method_miss; preserve unknown future strings. Known authorization_result values include authorized, not_public, not_applicable, manifest_missing, target_missing, active_release_missing, unsupported_manifest_version, path_error, missing_cas_object, unfinalized_or_deleting_cas_object, size_mismatch, and unauthorized_cas_object. Known fallback_state values include active_release_missing, unsupported_manifest_version, and negative_cache_hit; preserve unknown future strings. result is the diagnostic body status, not the HTTP status of the SDK call, so host misses can still be successful CLI/MCP/SDK calls with would_serve: false. Do not treat resolve/diagnose as a fetch, cache purge, or cache-policy oracle; route method misses should inspect allow, CAS authorization/health failures should inspect or redeploy the affected static asset, and fresh host misses should inspect edge_propagation or rerun run402 up verify. Branch on structured JSON fields such as cache_class and preserve unknown cache classes.

Release observability exposes stable asset identity and public reachability. Inventories include release_generation, static_manifest_sha256, nullable static_manifest_metadata (file_count, total_bytes, cache_classes, cache_class_sources, spa_fallback), and static_public_paths[] when returned. site.paths lists release static assets; static_public_paths[] lists browser-visible public paths with public_path, asset_path, reachability_authority, direct, cache class, and content type. Plan and release diffs expose static_assets counters: unchanged/changed/added/removed, newly_uploaded_cas_bytes, reused_cas_bytes, deployment_copy_bytes_eliminated, legacy_immutable_warnings, previous_immutable_failures, and cas_authorization_failures.

Runtime route failure codes to branch on: ROUTE_MANIFEST_LOAD_FAILED (manifest/propagation), ROUTED_INVOKE_WORKER_SECRET_MISSING (custom-domain Worker secret), ROUTED_INVOKE_AUTH_FAILED (internal invoke signature), ROUTED_ROUTE_STALE (selected route failed release revalidation), ROUTE_METHOD_NOT_ALLOWED (method mismatch), PAYOUT_WALLET_REQUIRED / PAYOUT_WALLET_AMBIGUOUS / PAYOUT_WALLET_UNRESOLVED (priced-route payout setup), PAYMENT_PROOF_MISMATCH (stale or wrong x402 proof), and ROUTED_RESPONSE_TOO_LARGE (body over 6 MiB).

GitHub Actions OIDC deploys: link once, deploy with the same CLI

For repo-driven deploys, run402 does not need service keys or allowance files in GitHub secrets. Run a local link command once:

run402 ci link github --project prj_... --manifest run402.deploy.json
# Optional route authority for CI route declarations:
run402 ci link github --project prj_... --manifest run402.deploy.json --route-scope /admin --route-scope /api/*

That creates a deploy-scoped /ci/v1/* binding and writes a workflow that grants id-token: write, checks out the repo, and runs the existing deploy primitive:

permissions:
  contents: read
  id-token: write

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Deploy to run402
        run: npx --yes run402@3.7.5 deploy apply --manifest 'run402.deploy.json' --project 'prj_...'

CI deploys are intentionally narrow: site, functions, database, absent/current base, and route declarations only when the binding has covering --route-scope patterns. Without route scopes, CI cannot ship routes. Keep secrets, domains, subdomains, checks, non-current base, and broader trust changes in a local allowance-backed deploy. If the gateway returns CI_ROUTE_SCOPE_DENIED, re-link with exact scopes like /admin or final-wildcard scopes like /api/*, or deploy locally. Manage bindings with run402 ci list and run402 ci revoke.

In-function helpers: caller-context vs BYPASSRLS

Inside a deployed function, import from @run402/functions. Two distinct DB clients keep RLS clean:

import { db, adminDb, auth, email, ai } from "@run402/functions";

export default async (req: Request) => {
  const user = await auth.requireUser();

  // Caller-context: db() mints a 60s actor JWT so run402.current_user_id() resolves in RLS.
  // No .eq("user_id", user.id) needed: RLS already binds the visitor's rows; the redundant
  // filter is a deploy-fail (R402_AUTH_REDUNDANT_USER_FILTER) under @run402/functions v3.0+.
  const mine = await db().from("items").select("*");

  // BYPASSRLS: for platform-authored writes (audit logs, cron cleanup, webhook handlers).
  await adminDb().from("audit").insert({ event: "items_read", user_id: user.id });

  // Send mail from the configured default outbound mailbox.
  if (mine.length === 0) {
    await email.send({ to: user.email, subject: "Welcome", html: "<h1>hi</h1>" });
  }

  return Response.json(mine);
};

adminDb().sql(query, params?) runs raw parameterized SQL and always bypasses RLS. It returns a flat Promise<Record<string, unknown>[]> (just the rows, no envelope):

import { adminDb, auth } from "@run402/functions";

export default async (req: Request) => {
  const user = await auth.requireUser();

  const rows = await adminDb().sql(
    "SELECT count(*)::int AS n FROM items WHERE user_id = $1",
    [user.id],
  );
  const n = (rows[0]?.n as number | undefined) ?? 0;
  return Response.json({ count: n });
};

@run402/functions is auto-bundled into deployed code; install it in your editor for full TypeScript autocomplete (also works at build time for static-site generation with RUN402_SERVICE_KEY + RUN402_PROJECT_ID set).

ai.generateImage({ prompt, aspect? }) is available inside deployed functions for live app flows such as generated avatars or OG images. It calls the project runtime image endpoint with RUN402_SERVICE_KEY, so deployed functions do not need allowance wallets or x402 signing code. Aspects are square, landscape, and portrait; the result is { image, content_type, aspect } with base64 image bytes. Runtime image generation is billed, rate-limited, and spend-capped against the project organization; public routed functions should authenticate/rate-limit their users before calling it.

assets.put(key, source, opts?) uploads bytes from inside a deployed function through the same CAS-backed apply substrate as deploy-time assets. It uses RUN402_SERVICE_KEY, accepts a string, Uint8Array, or { content | bytes }, and returns an SDK-compatible AssetRef with mutable and immutable URLs.

Calling from outside a function entirely (raw curl/fetch from CI scripts, bash bootstrappers, non-TS runtimes): service-key writes go to /admin/v1/rest/<table>, not /rest/v1/*. The gateway 403s service-role tokens on /rest/v1/* so a leaked key can't silently bypass RLS, which means curl ... > /dev/null against the wrong path looks like success but writes nothing. SQL-shaped admin work uses POST /projects/v1/admin/:id/sql (or run402 projects sql).

curl -X POST https://api.run402.com/admin/v1/rest/audit \
  -H "Authorization: Bearer $RUN402_SERVICE_KEY" \
  -H "Content-Type: application/json" \
  -d '{"event":"seed","ts":"2026-04-30"}'

SDK: @run402/sdk

npm install @run402/sdk

Two entry points:

• @run402/sdk: isomorphic. Bring your own CredentialsProvider (a session-token shim, a remote vault, anything that resolves project keys + auth headers). Works in Node 22, Deno, Bun, V8 isolates.

• @run402/sdk/node: Node-only convenience. Reads local profile state plus the project-key credential cache (credentials/project-keys.v1.json) and signs x402 payments from one deterministic source: an explicit opaque paymentSigner, explicit allowancePath, the supplied provider's readAllowance(), or the default active-profile allowance. Auth and payer may intentionally differ; a selected payment source never falls back to an ambient wallet. r.paymentPayer() reports only safe public payer/source provenance. Also exposes sites.deployDir(...), fileSetFromDir(...), typed deploy-manifest helpers (loadDeployManifest, normalizeDeployManifest), and resolveRun402TargetProfile() for app build scripts that need the same Core/Cloud target the CLI uses.

import { run402 } from "@run402/sdk/node";

const r = run402();
const project = await r.projects.provision({ tier: "prototype" });
const p = await r.project(project.project_id);
await p.assets.put("hello.txt", { content: "hi" });

The SDK is organised into focused namespaces: actions (Node recursive action runner), pay (bounded arbitrary-URL x402 buyer), projects, snapshots, branches, archives, assets, cache, ci, sites, functions, jobs, secrets, subdomains, domains, email (+ webhooks), senderDomain, auth, apps, tier, billing, contracts, ai, allowance, service, admin, operator (the human/email operator session: browser-delegated login + overview across every wallet that verified your email), wallets (signed server-side wallet label), orgs (org-owned control plane + r.org(id) sub-client), grants (per-project capability grants), and identityLinks (public dual-signature Nostr attribution), plus the r.project(id).apply hero for atomic mixed writes (release slices + assets slice via /apply/v1/*). Every operation throws a typed Run402Error subclass on failure: PaymentRequired, PaymentBuyerError, ProjectNotFound, Unauthorized, ApiError, NetworkError, LocalError, Run402DeployError. apply() automatically re-plans safe current-base BASE_RELEASE_CONFLICT races and emits apply.retry progress events. See sdk/README.md.

Buzz/Nostr agent identity links

An agent can publicly prove that its separately-held Buzz/Nostr key and Run402 EOA belong to the same principal. This is attribution only: projects remain organization-owned, and Nostr identities never authenticate, authorize, pay, deploy, or receive transfers. Run402 never accepts or derives from an nsec, Nostr private key, mnemonic, seed, or derivation path.

The human-facing install is a Buzz message—no terminal required:

Please install the run402.com skill.

That is the entire human instruction. In a managed Buzz context, first-party discovery routes it to run402-buzz; the agent reads the apex install router and installs the self-contained skill into its workspace (normally the user-home .buzz directory). The request means install and connect: after verifying the inert files, the agent loads the installed skill directly and continues through preflight, setup, and identity linking in the same turn. It does not stop at “available next turn” or ask a second setup question. For a Codex runtime, prefer supplying the working directory and environment separately to the agent's command runner:

working_directory: <user-home>/.buzz
environment: { "DO_NOT_TRACK": "1" }
command: npx --yes skills@latest add https://run402.com -s run402-buzz -a codex -y

Shell-only POSIX environments use:

cd "$HOME/.buzz"
DO_NOT_TRACK=1 npx --yes skills@latest add https://run402.com -s run402-buzz -a codex -y

Windows PowerShell uses:

Set-Location (Join-Path $HOME '.buzz')
$env:DO_NOT_TRACK = '1'
npx --yes skills@latest add https://run402.com -s run402-buzz -a codex -y

Claude Code uses -a claude-code, Goose uses -a goose, a confirmed .agents/skills consumer may use -a universal, and Claude Code plus Codex uses -a claude-code codex. universal is the shared path, not all runtimes; do not use the invalid explicit target -a claude. The skill bytes come from immutable digest-verified artifacts at run402.com; first-run npx can still require npm. GitHub is the one availability-only fallback, while any integrity failure stops before setup. Success reports the observed first-party digest and exact managed-workspace path; a GitHub source or global runtime path is never mislabeled first-party.

The file installation stage is inert. Continuing onboarding publishes a durable public kind-1 Nostr event and durable Run402 proof connecting the two public identities; revocation does not erase their history, and a Buzz-managed event may also expose its owner's public NIP-OA attestation. The agent initializes only if needed, creates or reuses the link, independently verifies it, and immediately offers one context-relevant quick test or demo with Deployment: none retained in the expanded receipt. On Windows the setup helper runs npm's and Run402's JavaScript entrypoints through the exact managed Node runtime with shell: false, avoiding .cmd process-boundary failures. It waits for explicit approval before building or deploying. After independently verifying the live app, it creates an inert durable offer and posts a normal HTTPS “Become an owner” handoff. The browser owns human login/passkey and the existing Buzz six-digit consent callback; no human terminal command or Buzz change is required.

See the buzz/ guide for prerequisites, the no-secret signer model, released-client fixtures, migration guidance, and the full workflow, or inspect the exact run402-buzz listing on skills.sh. The low-level CLI commands remain available for debugging, but they are not a competing onboarding path.

The community control plane keeps four concepts separate: installing the skill is inert shared capability; installing a community associates a Buzz relay community with a Run402 organization after dual consent; human adoption adds the Buzz owner as a distinct Run402 co-owner without demoting the founder agent; agent enrollment gives each later agent principal only bounded, expiring grants to named existing projects. A durable adoption offer is inert and separate from the short human/session-bound consent attempt. Buzz itself remains unchanged: approval uses already-shipped browser-fragment/kind-1 behavior plus released NIP-11/NIP-43 evidence, while Run402 owns offers, organizations, descriptor discovery, and lifecycle. run402 buzz status capability-detects older gateways; MCP only renders exact HTTPS/CLI handoffs. See the Fizz/Honey workflow.

Astro SSR + ISR cache (v1.52+). For Astro apps, use @run402/astro 1.0+: export default run402(); in astro.config.mjs returns an AstroUserConfig composing the SSR adapter (Lambda + SnapStart + ISR cache + AsyncLocalStorage request-context), image integration, and build-time detectors. Functions opt into the SSR class via FunctionSpec.class: "ssr" in ReleaseSpec; the gateway provisions SnapStart and caches HTML responses keyed by (host, path, search, method, locale, release_id). Cache is bypass-by-default (no-store unless Cache-Control explicitly allows it AND no Set-Cookie AND no auth-taint flag from auth.* helpers / payment primitives). Invalidate from in-function code or out-of-band: r.cache.invalidate(url) / r.cache.invalidatePrefix({ host, prefix }) / r.cache.invalidateAll({ host }) (SDK), run402 cache invalidate <url> (CLI). Inspect cached state with r.cache.inspect(url) / run402 cache inspect <url>. Agent DX helpers also in the CLI: run402 doctor (5 health checks), run402 dev (Astro dev with .env.local), run402 logs --request-id req_... (correlate across functions). Full reference at astro/README.md and cli/llms-cli.txt (R402_* SSR Runtime Error Codes section).

CLI: run402

npm install -g run402@latest

Every subcommand prints JSON to stdout, JSON errors to stderr, exits 0 on success and 1 on failure: designed for an agent shell, not a human. Full reference: cli/llms-cli.txt (also at https://docs.run402.com/llms-cli.txt).

up is the only compound CLI command: it calls the SDK action runner, emits steps[], and writes .run402/project.json when it needs to remember the workspace project. Against run402 Core it skips Cloud allowance/tier prerequisites and fails closed if no Core project is selected.

For database-bearing deploys, rehearse before commit. run402 apply --manifest app.json --rehearse --json plans, uploads missing CAS bytes, creates a contained branch, runs migrations/checks there, and exits nonzero on a failed rehearsal. If you already have a persisted plan id, use run402 deploy rehearse <plan_id> --project <id> --json. Manual restore points live under run402 snapshots create|list|get|restore|delete; restore is a two-step plan/confirm flow. Branch projects live under run402 branches create|list|renew|delete, default to a 7-day TTL, use sandboxed email by default, and are marked noindex.

Portable archives export the supported run402 Core runtime slice of a Cloud project for local Core import. This is the no-lock-in trust path, separate from allowance/spend-cap financial-risk controls.

run402 cloud archives create <project_id> --scope portable-runtime-v1 --auth stubs --consistency pause-writes --wait --output ./project.r402ar --json
run402 archives verify ./project.r402ar --json
run402 core projects import ./project.r402ar --name imported-project --env-file ./required.env --json
run402 projects export <project_id> --output ./project.r402ar --json
run402 core projects apply ./project.r402ar --name imported-project --env-file ./required.env --json

projects export is an alias for the Cloud archive export flow; core projects apply is an alias for Core archive import. Archive v1 excludes secret values, auth credentials, logs, billing/allowance state, Cloud operations metadata, Cloud import, and existing-project merge import. Verify is local/offline and checks integrity plus compatibility; archives remain untrusted input until Core import verifies and stages them.

The active project is sticky: run402 projects use <id> server-validates <id> and stores it as the default for subsequent <id>-taking subcommands, so most commands work without it. Local key material is managed separately under run402 credentials project-keys ...; that cache is never project inventory.

MCP server: run402-mcp

npx -y run402-mcp                        # standalone test

Buying only? Load 6 tools instead of 198

The full server registers 198 tools (~43,000 tokens) before you do anything. If your agent only wants to buy — generate an image for $0.03 and nothing else — that is a fifth to a third of a context window spent on 192 tools it will never call.

RUN402_MCP_PROFILE=buyer npx -y run402-mcp

The six: generate_image · init · check_balance · allowance_status · allowance_export · request_faucet — enough to bootstrap a wallet, fund it, check it, and buy. Local, so it can actually pay: an x402 payment needs a signing key, so a wallet-less remote server cannot make one.

Default is unchanged when the variable is unset. An unknown profile name exits 1 with the known-profile list rather than silently serving the full surface or nothing.

Remote endpoint (no install)

A hosted streamable-HTTP MCP server runs at https://mcp.run402.com/mcp with free discovery tools only: run402_quickstart, x402_price_check (decode any URL's x402 challenge, unpaid), and experiment_scoreboard. It never handles funds — paid capabilities (image generation, deploys, payments) require the local server below, which holds your wallet. Registry entry com.run402/mcp lists both (packages[] npm + remotes[]). The remote itself runs as a run402 function — the platform hosting its own MCP server.

Stdio MCP transports must keep stdout reserved for JSON-RPC. Use the package bin (npx -y run402-mcp) or node dist/index.js from a built checkout. If a host insists on npm start, set npm_config_loglevel=silent; npm's lifecycle banner is stdout and otherwise appears as non-JSON prelude. The repo .npmrc and Docker image set this for source/container hosts.

OpenClaw skill

cp -r openclaw ~/.openclaw/skills/run402
cd ~/.openclaw/skills/run402/scripts && npm install

Each script re-exports from cli/lib/*.mjs: the OpenClaw command surface is identical to the CLI command surface by construction. See openclaw/README.md.

MCP tools

The full MCP surface: every tool is a thin shim over an SDK call.

Database

Asset storage (content-addressed CDN)

Sites & subdomains

Snapshots & branches

CI/OIDC bindings

Functions & secrets

Auth & email

AI helpers

External x402 buyer

Apps marketplace

Tier & billing

KMS signers (on-chain signing)

Allowance & organization

Service status (no auth)

Configuration

Local state lives at:

• profile state.json: active project pointer and profile state

• profile credentials/project-keys.v1.json (0600): local anon/service key cache for explicit credential-required operations

• ~/.config/run402/allowance.json (0600): wallet for x402 signing

Legacy projects.json files are one-way migration input only. anon_key and service_key have no expiry; lease enforcement happens server-side. Inspect cache state with run402 credentials project-keys status --project <id> and export secrets only with run402 credentials project-keys export --project <id> --reveal.

Development

npm run build           # builds core/, sdk/, then the MCP server
npm test                # SKILL + sync + unit tests
npm run test:e2e        # builds generated CLI SDK mirrors, then runs CLI end-to-end tests
npm run test:sync       # checks MCP/CLI/OpenClaw/SDK stay in sync
npm run test:skill      # validates SKILL.md frontmatter + body

Architecture: every tool / subcommand / skill script is a thin shim over an @run402/sdk call. core/ holds Node-only filesystem primitives (keystore, allowance, SIWE signing) wrapped by the SDK's Node provider. See CLAUDE.md for the full layout.
