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)

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

Client Configuration

Claude Desktop / Claude Code

json

{
  "mcpServers": {
    "bart": {
      "url": "https://bart-mcp.srivastsh.workers.dev/mcp"
    },
    "muni": {
      "url": "https://muni-mcp.srivastsh.workers.dev/mcp",
      "headers": {
        "x-api-key-511": "YOUR_511_API_KEY"
      }
    }
  }
}

Poke

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

Cursor / Windsurf / stdio-only Clients

Use mcp-remote as a bridge:

json

{
  "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

bash

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

bash

cd muni-mcp
npm install
wrangler deploy

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

bash

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)
