APIClaw
APIClaw is an MCP server that gives AI agents unified access to 18 direct-call providers (AI/LLM, voice, SMS, email, search, code, dev tools), 1,636 open APIs, and 22,392+ discoverable APIs — with built-in authentication, rate limiting, and usage tracking.
API Discovery: Search APIs via natural language, browse by category, and retrieve detailed specs (including compact formats to save context tokens)
Direct API Calls: Execute calls to 18 pre-configured providers without managing API keys or configuration
Capability-Based Routing: Describe an action (e.g., "send SMS", "search web") and APIClaw automatically selects the best provider with fallback support
API Chaining: Build multi-step workflows with sequential, parallel, conditional, and loop execution — including async chains, webhooks, per-step retry logic, and resume-from-failure
Dry-Run Testing: Preview any API call without real execution to test and debug workflows
Workspace & Billing: Register for a workspace, monitor usage/costs/rate limits, manage team access, check credit balance, add credits, purchase API access, and set up metered pay-per-call billing
Multi-Client Support: Works with Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Continue, and Codex (OpenAI)
Allows privacy-focused web searching to retrieve information without tracking through the Brave Search API.
Provides real-time speech-to-text and transcription capabilities across multiple languages.
Enables high-quality text-to-speech generation, realistic voices, and voice cloning in 29 languages.
Provides tools to manage repositories, issues, pull requests, and actions through the GitHub API.
Provides access to Google Search data and real-time SERP results for information retrieval.
Provides access to over 1,000 machine learning models for tasks including image, video, and audio generation.
Enables programmatic sending of emails with high deliverability through a developer-friendly API.
Facilitates global SMS and programmable messaging services across more than 180 countries.

APIClaw 🦞
The Control Plane for AI Agents. One runtime for model routing and 26,619 discoverable APIs, including 689 current catalog entries matched to source-verification evidence by exact name. Discovery, routing, missions, and observability live on one rail. Sign in once with apiclaw auth login; the same credential works across local MCP, CLI, HTTP gateway, and Remote MCP.
Route across supported models from OpenAI, Anthropic, OpenRouter, xAI, Groq, Mistral, Cohere, DeepInfra, or a configured endpoint. Switch with one parameter, no SDK swap, no lock-in.

Managed where it matters | APIClaw inventories 22 server-side managed adapters. Four provider rails are customer-executable now: OpenRouter chat, Brave Search, GitHub read-only, and NASA read-only. Adapter inventory is not an execution promise. Runtime readiness is explicit and unknown-cost customer traffic fails closed. |
Install
# 1. Install (Claude Desktop)
# Download and open: https://apiclaw.cloud/apiclaw.mcpb
# 2. Or any MCP-compatible client
npm install -g @nordsym/apiclaw
# 3. Sign in once. Works across all doors.
npx @nordsym/apiclaw auth loginAdds APIClaw as an MCP server in Claude Desktop, Cursor, Windsurf, OpenClaw, or any MCP-compatible agent. The auth flow opens the browser, signs you in via Google one-tap, and writes ~/.apiclaw.toml. The free workspace includes up to 25 managed calls for its lifetime, subject to a $1 total underlying provider-cost cap. Discovery stays free. Billing-ready managed actions can continue beyond that at provider cost + 15%; variable-cost actions without an exact adapter remain blocked.

What you can call
Discoverable (26,619)
The full registry, searchable via discover_apis(query). Every entry tagged by category, health-ranked by recent success-rate, callable-or-not flagged.
Exact-name source-verified (689)
These current public catalog entries map to source-verification evidence by exact name. Source verification is discovery evidence, not proof that APIClaw can execute the API.
Managed adapter inventory (22) - APIClaw has server-side adapter and credential support. Inventory alone does not enable customer execution.
Customer-executable providers (4) - OpenRouter chat, Brave Search, GitHub read-only actions, and NASA read-only actions.
Source-verified definitions (689) - Discovery-only unless the result also exposes an explicitly customer-executable managed action.
Mission templates
Customer templates appear only after every cost-bearing step has a verified cost adapter. GenPRD remains internal until that contract is exact.
Pricing
Plan | Price | Access |
Free | $0 forever | Up to 25 managed calls for the lifetime of the workspace, subject to a $1 total underlying provider-cost cap. Discovery is free. Free email signup required. |
Pay as you go | Provider cost + 15% margin | Billing-ready managed actions continue after the free allowance. Per-request provider cost, customer charge, and margin are recorded. Actions without an exact billing adapter remain blocked. |
Pricing canon: underlying provider cost plus a 15% margin. Stripe metered billing live.
