lumind-mcp

Make Lumind a native tool for any AI agent.

lumind-mcp is a Model Context Protocol server that exposes the Lumind agentic-commerce platform as a handful of clean tools. Plug it into an AI agent (Claude Desktop, an IDE, a custom agent) with a capped agent key, and the agent can, in its own tool language, browse the Lumind service catalogue, check how much budget it has left, launch a GEO/SEO scan on a domain, and read back the structured report.

Why it exists

AI agents are great at deciding what to do but need safe, well-described tools to actually do it. Lumind already runs the work (GEO/SEO scans) and the billing. This MCP server is the adapter between the two: every action goes through the agent's capped LUM key, so the agent can spend autonomously but can never exceed the budget the human set. The result is hands-off agentic commerce with a hard spending ceiling.

How spending stays safe

• Every call carries the agent key (lmd_agent_...), a key the human created with a total cap and a daily cap.

• lumind_run_scan is the only tool that spends LUM. It is money-first: budget is debited when the scan is accepted, before any report is produced.

• Budget failures come back as plain, actionable messages: insufficient LUM (402), cap reached or key revoked (403), daily cap reached (429).

• Pass an idempotencyKey when retrying a scan so a retry never double-spends.

Tools

Install & build

Requires Node.js >= 18.

npm install
npm run build

Configuration

The server reads its configuration from the environment:

Use it in an MCP client

Add this to your MCP client config (e.g. claude_desktop_config.json), pointing args at the built entrypoint:

{
  "mcpServers": {
    "lumind": {
      "command": "node",
      "args": ["/absolute/path/to/lumind-mcp/dist/index.js"],
      "env": {
        "LUMIND_AGENT_KEY": "lmd_agent_xxxxxxxxxxxxxxxx",
        "LUMIND_API_BASE": "https://lumind.io"
      }
    }
  }
}

After npm run build you can also run it directly:

LUMIND_AGENT_KEY=lmd_agent_xxxx node dist/index.js   # stdio transport

Use it remotely over HTTP

The same four tools are also served over a remote Streamable HTTP endpoint, so any MCP client that supports remote servers can connect to a single URL with its own capped agent key , no local subprocess needed.

The key travels in each request's Authorization header (never a server env var), so one HTTP server safely serves many isolated clients at once. Each request gets a fresh, stateless session.

{
  "mcpServers": {
    "lumind": {
      "type": "http",
      "url": "https://mcp.lumind.io/mcp",
      "headers": {
        "Authorization": "Bearer lmd_agent_xxxxxxxxxxxxxxxx"
      }
    }
  }
}

If the dedicated mcp.lumind.io host is not yet live, use the fallback path on the main domain instead:

"url": "https://lumind.io/mcp"

Run the HTTP transport yourself:

npm run build
MCP_HTTP_PORT=8120 LUMIND_API_BASE=https://lumind.io node dist/http.js   # binds 127.0.0.1

HTTP smoke test

A minimal MCP initialize against the local endpoint (replace the key with a real one):

curl -s -X POST http://127.0.0.1:8120/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer lmd_agent_xxxx" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"smoke","version":"0.0.0"}}}'

A healthy server replies 200 with an SSE data: line carrying the initialize result (serverInfo.name = "lumind-mcp"). A request without the Authorization header is rejected with 401. There is also a plain GET /healthz returning {"status":"ok"}.

Develop & test

npm run dev      # run from source over stdio (tsx)
npm run dev:http # run the HTTP transport from source (tsx)
npm run smoke    # offline smoke test: checks tool registration + a mocked call, no network

Transport

• stdio (dist/index.js), the standard way MCP clients spawn a local server as a subprocess. One capped key per process via LUMIND_AGENT_KEY.

• Streamable HTTP (dist/http.js), a remote, multi-client endpoint. Each request brings its own agent key in the Authorization header; sessions are stateless and isolated, so N instances run independently with no shared key or cross-request state.
