TrainTrack MCP

An MCP server for TrainTrack that gives AI agents access to Indian Railways train search, schedules, live status, trains between stations, station data, and PNR status.

It uses the MCP stdio transport, requires no API key, and talks to https://traintrack.stupidlabs.lol/ by default. TrainTrack uses unofficial NTES/Indian Railways data, which may occasionally be delayed, incomplete, or unavailable. Confirm time-sensitive journey details through official railway channels.

Requirements

• Node.js 18 or newer
• An MCP-compatible client

Installation

After the package is published:

npm install --global traintrack-mcp

To run it directly from a source checkout:

npm install
npm start

MCP client configuration

No environment variables are required for the hosted TrainTrack API.

Claude Desktop, Claude Code, Cline, and compatible clients

Add this to the client's MCP configuration:

{
  "mcpServers": {
    "traintrack": {
      "command": "npx",
      "args": ["-y", "traintrack-mcp"]
    }
  }
}

Codex

Add this to ~/.codex/config.toml:

[mcp_servers.traintrack]
command = "npx"
args = ["-y", "traintrack-mcp"]
tool_timeout_sec = 60

OpenCode

Add this to ~/.config/opencode/opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "traintrack": {
      "type": "local",
      "command": ["npx", "-y", "traintrack-mcp"],
      "enabled": true
    }
  }
}

Configuration

Environment variable	Default	Description
TRAINTRACK_BASE_URL	https://traintrack.stupidlabs.lol	TrainTrack deployment to use. http and https URLs are supported, including deployments under a path.
TRAINTRACK_TIMEOUT_MS	30000	Positive request timeout in milliseconds.

For example:

{
  "mcpServers": {
    "traintrack": {
      "command": "npx",
      "args": ["-y", "traintrack-mcp"],
      "env": {
        "TRAINTRACK_BASE_URL": "https://trains.example.com/"
      }
    }
  }
}

Tools

Tool	Inputs	What it returns
search_trains	query	Trains matching a name, number, or text
get_train_info	train_number	Train identity, endpoints, and running instances
get_train_schedule	train_number, optional date	Scheduled stops, times, running days, and coordinates
get_train_live_status	train_number, optional date	Live stops, delays, platforms, current reported position, and route geometry
find_trains_between_stations	from, to, optional sort	Direct trains between two station codes
get_train_exceptions	train_number	Exceptional service information such as cancellations or diversions
get_pnr_status	pnr	Booking, passenger, train, and chart status
get_station_coordinates	code	Bundled station name and coordinates
search_stations	query, optional limit	Stations matching a name or code
track_trains	train_numbers	Batched live tracking for up to 10 trains
check_traintrack_health	none	Public API availability and service status

Dates use DD-MMM-YYYY, for example 26-Jul-2026. Train numbers contain 4–6 digits, station codes contain 1–10 letters or digits, and a PNR contains exactly 10 digits.

Rate limits

TrainTrack applies these default limits per client IP and per endpoint. This MCP server does not add another rate limiter. An upstream 429 response is returned to the MCP client as a tool error with its HTTP status, response details, and X-Request-ID when available.

Operation	Default upstream limit
Train search	60/minute
Train information	30/minute
Train schedule	20/minute
Live train status	12/minute
Trains between stations	20/minute
Train exceptions	20/minute
PNR status	2/minute
Station coordinates	120/minute
Station search	120/minute
Batched live tracking	6/minute
Health check	120/minute

The hosted service also protects its railway-data provider from overload, so temporary 502 errors can occur even before a client endpoint limit is reached. Wait briefly before retrying a 429 or 502 response.

Cache and data freshness

Caching happens in TrainTrack, not in this MCP process. The MCP tools return the upstream response unchanged, including its cached field. A response with "cached": true came from an earlier identical request or was shared with a simultaneous identical request; it does not mean the data was just refreshed.

Data	Maximum default cache window
Live running status	45 seconds
Train exceptions/service updates	5 minutes
Train information	30 minutes
Current running instance	30 minutes
Trains between stations	30 minutes
Train search	12 hours
Train schedules	12 hours

PNR results are never stored in the result cache. Identical simultaneous PNR requests may still share one in-flight lookup. Treat PNRs as sensitive travel information and avoid putting real values in shared logs, screenshots, or telemetry.

See the hosted TrainTrack API documentation for the full API behavior.

Development

npm install
npm run check
npm test

The project uses ESM throughout and relies on Node's built-in Fetch API.
