Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Bay Area Transit MCP Servers

Two Cloudflare Workers providing MCP (Model Context Protocol) access to BART and SF Muni real-time transit data. Works with Claude, ChatGPT, Poke, Cursor, and any MCP-compatible client.

You don't need to deploy anything. Just point your MCP client at the hosted endpoints below.

Live Endpoints

  • BART: https://bart-mcp.srivastsh.workers.dev/mcp — no auth, just connect
  • Muni: https://muni-mcp.srivastsh.workers.dev/mcp — pass your free 511.org API key via x-api-key-511 header

These run on Cloudflare Workers' free tier (100k requests/day). Since the Muni server uses BYOK auth, each user's 511 rate limit is isolated to their own key.

Quick Start

BART (no auth required)

Just add the URL to your MCP client. No API key needed.

Muni (BYOK)
  1. Get a free 511.org API key at https://511.org/open-data/token
  2. Pass it via the x-api-key-511 header in your MCP config

One-click setup: BART recipe | Muni recipe

Or add manually as a remote MCP server:

  • URL: https://bart-mcp.srivastsh.workers.dev/mcp or https://muni-mcp.srivastsh.workers.dev/mcp
  • For Muni, set custom header x-api-key-511 to your 511 key

Use mcp-remote as a bridge:

{
  "mcpServers": {
    "bart": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/mcp-remote", "https://bart-mcp.srivastsh.workers.dev/mcp"]
    },
    "muni": {
      "command": "npx",
      "args": [
        "-y", "@anthropic-ai/mcp-remote",
        "https://muni-mcp.srivastsh.workers.dev/mcp",
        "--header", "x-api-key-511:YOUR_511_API_KEY"

Deploy Your Own

Most users don't need to deploy — just use the hosted endpoints above. But if you want your own instance:

Prerequisites
  • Node.js 18+
  • Cloudflare account (free tier works)
  • wrangler CLI: npm install -g wrangler
BART Worker
cd bart-mcp
npm install
wrangler login
wrangler deploy

The public BART demo key (MW9S-E7SL-26DU-VV8V) is baked into wrangler.toml. No secrets needed.

Muni Worker
cd muni-mcp
npm install
wrangler deploy

Optionally set a fallback 511 key (used when no header key is provided):

wrangler secret put API_511_KEY

Architecture

  • Runtime: Cloudflare Workers (V8 isolates)
  • Transport: WebStandardStreamableHTTPServerTransport (stateless, one server per request)
  • Auth: BYOK via request headers, optional env secret fallback
  • Validation: Zod schemas for all tool inputs
  • CORS: Enabled for all origins
  • API Sources: api.bart.gov (BART), api.511.org (Muni/511)
