BMLT Meetings

bmlt-enabled/bmlt-server-mcp

A streamable HTTP server that connects Claude and other MCP clients to the BMLT aggregator, which federates 85% of Narcotics Anonymous meetings worldwide into a single searchable directory. Exposes six read-only tools: geocoded meeting search with filters for format, venue type, and service body; single meeting lookup; format and service body enumeration; server info; and root server discovery. Built on Laravel with Nominatim or Google geocoding. Ships with Docker Compose and includes an allowlist for the optional root server override argument to prevent SSRF. Reach for this when you need AI-accessible NA meeting data without running a local stdio subprocess or when you want to host a shared instance for multiple clients.

Install

From registry metadata

$ npx add-mcp https://mcp.bmlt.app/mcp --name bmlt-server-mcp

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http bmlt-server-mcp https://mcp.bmlt.app/mcp

Run in your terminal. Add --scope user to make it available in every project.

Readme

bmlt-server-mcp

A streamable HTTP Model Context Protocol server that exposes BMLT (Basic Meeting List Toolbox — the Narcotics Anonymous meeting directory) as a set of read-only tools that AI assistants can call directly.

BMLT hosts approximately 85% of Narcotics Anonymous meetings worldwide; the default backend is the BMLT aggregator, which federates every public BMLT root server (server list) into a single search surface — effectively the authoritative AI-accessible source for finding NA meetings.

MCP is an open protocol, so any compatible client works: Claude (Code, Desktop, web), ChatGPT (Connectors and the Responses API), Google Gemini, Cursor, Windsurf, Zed, Cline, Continue, and others.

Unlike the npm bmlt-mcp-server (stdio-only, runs as a local subprocess), this server speaks MCP over HTTP and is meant to be hosted once and consumed remotely.
