Official

@verifiedstate/mcp

Official MCP bridge for VerifiedState — connect Claude Code, Cursor, Windsurf, and other MCP clients to verified memory and Proof Meter.

This package runs a local stdio MCP server that proxies tool calls to the hosted endpoint. Your API key never leaves your machine except as Authorization: Bearer to VerifiedState.

MCP configuration

Cursor

Add to your MCP config (e.g. Cursor Settings → MCP), replacing the placeholder key:

{
  "mcpServers": {
    "verifiedstate": {
      "command": "npx",
      "args": ["-y", "@verifiedstate/mcp"],
      "env": {
        "VERIFIEDSTATE_API_KEY": "vs_live_YOUR_KEY_HERE",
        "VERIFIEDSTATE_NAMESPACE_ID": "optional-default-namespace-uuid"
      }
    }
  }
}

Claude Code

Same shape as Cursor — merge into your Claude Code MCP configuration:

{
  "mcpServers": {
    "verifiedstate": {
      "command": "npx",
      "args": ["-y", "@verifiedstate/mcp"],
      "env": {
        "VERIFIEDSTATE_API_KEY": "vs_live_YOUR_KEY_HERE"
      }
    }
  }
}

Windsurf

Use the equivalent MCP server entry in Windsurf’s config (stdio command + env):

{
  "mcpServers": {
    "verifiedstate": {
      "command": "npx",
      "args": ["-y", "@verifiedstate/mcp"],
      "env": {
        "VERIFIEDSTATE_API_KEY": "vs_live_YOUR_KEY_HERE"
      }
    }
  }
}

Remote HTTP (if your client supports it)

Point the client at https://mcp.verifiedstate.ai/mcp and configure Bearer authentication with your API key. The exact JSON shape depends on the product; refer to your client’s docs for “remote MCP” or “SSE/HTTP MCP”.

Programmatic config helper

import { getConfig } from '@verifiedstate/mcp';

const config = getConfig('vs_live_...', 'optional-namespace-id');
// => { mcpServers: { verifiedstate: { command, args, env } } }
