Use your AI agent to plan trips in San Francisco and the Bay Area. Results show where to walk, which buses or trains to take, where to transfer, and when to depart and arrive.
Free to use. No API keys or authentication. Connect an AI agent or app that supports remote MCP servers, or run the server on your computer. MCP connects AI apps to tools. Apps that support MCP Apps can display interactive trip details. The hosted service runs on Cloudflare Workers Free. Transitous provides trip planning, place search, and stop departures.
“How do I get from the Ferry Building to Baker Beach, leaving now?”
“I need to reach the Ferry Building by 9 tomorrow morning.”
“Compare transit with cycling, and avoid more than one transfer.”
“What departs next from Embarcadero BART?”
“Show the next Muni N departures at Embarcadero.”
The default provider is for light, noncommercial, open-source use. It is a community service, and availability is not guaranteed. See provider details.
In your AI agent's MCP or connector settings, add a remote server with the official hosted URL:
Set authentication to None if asked.
Ask: “How do I get from the Ferry Building to Baker Beach, leaving now?”
The user guide and IT review explain setup, tool permissions, data handling, support, and service limits. Place searches, trip coordinates, and requested stop IDs and departure times are sent to Transitous; see the privacy policy.
Requires Node.js 22.12 or newer and Git.
For Claude Desktop, add this to its MCP configuration. It installs the server from this public repository and starts it:
Restart Claude Desktop and ask for a trip. For Claude Code:
From the project directory:
For Claude Desktop, replace the example below with the full path to your local copy:
Restart Claude Desktop. For Claude Code, register the same local server:
The server starts without credentials or environment variables. Include your starting address in the trip request, or use an address already in your conversation. This service does not save a home address. When several places match, choose the intended place before planning the trip.
Privacy: place searches, trip coordinates, and requested stop IDs and departure times go to Transitous. Its privacy policy says request URLs are logged for up to two days. This application's code does not log or save addresses or trip results. Your AI app and hosting providers have their own retention practices. The project privacy policy explains who receives the data and how it is handled.
For help, see Support or open a GitHub issue. Send security or privacy reports to [email protected]; see Security.
Transit trips include walking to and from stops. You can limit transfers, request the wheelchair routing option, or compare transit with walking or using your own bicycle. Results include readable instructions and data the app can display.
MCP compatibility: supports protocol version 2026-07-28 over Streamable HTTP for remote connections and stdio for local connections. Older versions are also supported. Local tests check both current and older connection procedures. See the tested versions and client limitations.
Times use America/Los_Angeles, the Bay Area's Pacific timezone, including daylight-saving changes. Travel time and the wait before departure are shown separately. Each bus, train, or ferry section identifies timetable times or live predictions. The provider does not report how old its predictions are. A live prediction may be out of date.
In apps that support MCP Apps, including Claude, plan_trip also displays interactive trip details:
Selecting a trip and opening details use the results already returned. Refresh requests the trip again and uses the same request limits as an ordinary trip search. The view does not update automatically or load external maps. Apps without MCP Apps support receive readable trip instructions and the same result data.
The interactive view supports light and dark themes, narrow screens, keyboard controls, and fullscreen details where the app supports them. It shows trip options and each part of the trip in order. It does not include a street map.

Transitous lists data sources for Muni, BART, Caltrain, AC Transit, VTA, SamTrans, and regional ferries. Available trips and predictions depend on the data currently supplied. Place search is limited to the Bay Area. Walking instructions describe connections between places and stops, without turn-by-turn directions. The wheelchair routing option applies to walking and transfer paths. Vehicle accessibility may be unknown; check each transit section. The data does not confirm current elevator operation or guarantee accessible entrances and paths. Results do not include fares, tickets, service alerts, or bike-share availability.
Ask for upcoming departures at a stop to open a departure board. In trip details, select Next departures at this stop at a boarding step. Each departure identifies a live estimate or scheduled time, plus the route, destination, agency, platform, cancellation, and boarding information when supplied.
The board shows service, destination, and departure time in three columns. Live or scheduled status appears beneath the time. Service names stay complete, and a scheduled comparison appears only when its displayed date or time differs from the departure estimate.
Select Refresh to request that board again. This does not change the selected trip. Route and destination filters narrow the results already loaded; they do not fetch more departures. There is no automatic polling or retry. Retrieved shows when the result was fetched, not when the agency last updated its predictions. Times use Pacific time.
The screenshots below show the interactive view with example data, not current departures.

The same code serves remote MCP connections at /sf-transit/mcp using Streamable HTTP. Existing /mcp connections continue to work. It uses no Containers, databases, storage bindings, API keys, OAuth, or background jobs. Running the server on your computer avoids a separate hosting service. Workers Free provides a free hosting allowance. The person deploying the service needs a Cloudflare account; people connecting to the MCP endpoint do not.
Build and preview locally:
build:worker builds locally without deploying. The local test URL is http://localhost:8787/sf-transit/mcp.
To publish to your own Cloudflare account, review wrangler.jsonc, use a Workers Free account, and run Wrangler's deploy command yourself. Connect your remote MCP client to the resulting https://<worker>.<subdomain>.workers.dev/sf-transit/mcp URL, with no authentication. An agent running in the cloud cannot use your computer's localhost URL.
For a Claude remote connector, set vars.PUBLIC_MCP_URL in wrangler.jsonc to the exact connector URL, including /sf-transit/mcp, with no trailing slash. Claude uses a separate web address for the interactive view. The server calculates that address from this URL. You do not need to register the view's address. Leave the value empty for local use or to let the app choose its default address. If the connector URL changes, update this value too.
Reindex Ventures LLC's production configuration targets https://mcp.riv.lc/sf-transit/mcp. The named production environment in wrangler.jsonc configures the sf-transit-mcp Worker, its company hostname, and a root redirect to https://reindexventures.com. The repository remains czekaj/sf-transit-mcp.
For Cloudflare's connected Git build, use npm run build:widget as the build command and npx wrangler deploy --env production as the deploy command. Production URL variables come from this configuration; no manual URL variables or alternate configuration file are needed. The default configuration has no custom domain, so forks can deploy independently. See the Cloudflare deployment guide.
Check the maintainer configuration locally without deploying:
A public deployment must follow Transitous's usage policy. Coordinate with its maintainers before serving many users or sending substantial automated traffic. Each running server or Worker instance limits Transitous requests to 20 in the previous minute and 600 in the previous 24 hours. These limits reset when an instance restarts and do not limit total requests across all instances. The service does not request updates in the background or retry automatically. A stop-departure request makes one Transitous request. A normal transit search makes one Transitous request. Comparing transport modes makes one request per mode.
Tests use fictional examples and simulated service responses. They do not call live transit APIs. Worker builds and type generation run locally. After changing Wrangler configuration, regenerate types:
Preview the interactive view with fictional transit services and public-place examples:
Open http://127.0.0.1:8798. The preview uses the MCP Apps connection in an isolated frame. Controls show light and dark themes, narrow screens, empty results, and failed refreshes. It makes no transit API requests. Rebuild and reload after editing the view. npm run build:widget creates its HTML and an MCP resource identified by the file contents. Generated files are not committed.
The MCP connection, Transitous requests, and display code are separate. Requests and responses follow the MOTIS API version linked by Transitous. See CONTRIBUTING.md for contribution and testing guidance.
The Claude submission materials contain listing copy, reviewer instructions, approved screenshot assets, and the remaining launch requirements. The listing is a draft. Provider use remains subject to Transitous's published policy; qualifying light use does not require separate prior approval.
The hosted service is listed in the official MCP Registry as io.github.czekaj/sf-transit-mcp. The publication guide records the verified submission, offline manifest validation, manual publishing workflow, and approvals required for later publications.
The widget preview also includes standalone BART, Muni, and Caltrain departure boards and a board opened from trip details, all using fictional examples. The Caltrain example checks long service names and duplicate scheduled times.
The SF icon combines the Golden Gate Bridge, transit route endpoints, and a streetcar. Its original AI-generated PNG is assets/route-monogram.png, with the generation prompt alongside it. MCP server, tool, and resource descriptions include a PNG icon, following the MCP icons specification. Apps choose whether to display it.
The Worker also serves the 512 × 512 PNG at /sf-transit/icon.png for directory forms that require a hosted icon URL. After deployment, the company URL is https://mcp.riv.lc/sf-transit/icon.png. It serves the image directly without authentication or a redirect, using the existing Worker rather than a separate image-hosting service.
Run npm run build:branding to create the logo, icon sizes, and assets/social-preview.png from the original artwork. The script crops and resizes the selected image; it does not call an image service. If the source image changes, adjust the cropping and sizing in scripts/build-branding.mjs. The social preview is a 1280 × 640 image for GitHub's Settings → Social preview. Committing it does not change that setting. Artwork uses the project's MIT license.
Code: MIT. Transit and map data retain their own licenses.
