Real-time SF Muni departures, routes, alerts, vehicle positions, and schedules. This MCP server exposes transit data via Cloudflare Workers, enabling MCP-compatible clients to access live Muni information without deployment.

🛠️ Key Features

Real-time SF Muni data: departures, routes, alerts, vehicle positions, and schedules
MCP protocol access via hosted endpoints
No deployment required for clients
Separate endpoints for BART and Muni data
Cloudflare Workers-based deployment (free tier capable)

🚀 Use Cases

Integrate SF Muni live data into MCP-enabled chatbots and analytics tools
Build transit dashboards with real-time scheduling and vehicle positions
Enable lightweight client apps to fetch Muni info via MCP protocol

⚡ Developer Benefits

Simple client setup: point MCP client to hosted endpoints
No authentication for BART endpoint; optional 511.org API key for Muni
Clear readme excerpt guides deployment and usage
Works with Claude, ChatGPT, Poke, Cursor, and any MCP-compatible client

⚠️ Limitations

Cloudflare Workers free tier limits apply (100k requests/day)
Muni endpoint requires 511.org API key via header for access
Data freshness depends on upstream transit feeds and Cloudflare deployment

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

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

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
