Transit MCP MCP server

Which MCP servers are Transit MCP's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.transitmcp/transit-mcpverified in the MCP registry

The registry name sits under transitmcp.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

Should an agent connect itConnect it
  • Its tools do every use case we checked: route a journey across local transit lines through an AI assistant; find the next departure from a nearby station; check which transit lines have service disruptions today.

Once connected

  • For "route a journey across local transit lines through an AI assistant", the likely first call is plan_trip.
  • For "find the next departure from a nearby station", the likely first call is find_transit.
  • Parameters are untyped or undescribed in 12 of 18 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • get_departures

    Find what leaves a stop next, the first service or last service in a bounded window. Pass a stopRef from find_transit, or a stop name with its coverage: a name for one place covers all its stations in that network (otherStations lists the…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "transit-mcp": {
      "type": "http",
      "url": "https://transitmcp.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http transitmcp https://transitmcp.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://transitmcp.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
