### Description (declared)

# STPT MCP

[![CI](https://github.com/vladirocox/stpt-mcp/actions/workflows/ci.yml/badge.svg)](https://github.com/vladirocox/stpt-mcp/actions/workflows/ci.yml)

An unofficial, standalone [Model Context Protocol](https://modelcontextprotocol.io/)
server for **STPT public transport in Timișoara**, Romania. It exposes live
arrivals, date-aware schedule fallback, service alerts, vehicle positions, and an
offline stop/route index to MCP clients over **stdio** or **Streamable HTTP**.

> This project is not affiliated with, endorsed by, or operated by STPT or the
> Timișoara municipality. Upstream data is used with caching and conservative
> request limits. Do not use it for safety-critical decisions.

## In action

![An assistant answering "when does the 14 get to Piata Marasti?" with the stpt MCP tools](https://raw.githubusercontent.com/vladirocox/stpt-mcp/main/assets/chat-arrivals.png)

Ask in plain language. The assistant calls `search_stops` to resolve the stop,
then `get_arrivals` for the departures, and answers with the next bus. The same
tools work from any MCP client — Claude, Hermes, Cursor, or an agent of your
own.

## Highlights

- Seven read-only MCP tools with typed output schemas.
- Live-first arrivals with **date- and shape-aware schedule fallback**, explicit
  provenance, and last-known-good stale data.
- Bounded TTL caches with **single-flight** refresh. Fifty concurrent calls to one
  stop produce one live upstream request, not fifty.
- Bounded upstream concurrency, timeouts, retries with jitter, `Retry-After`
  support, and response-size limits.
- Bundled GTFS-derived network snapshot, so stop/route discovery works offline.
- stdio and Streamable HTTP through the official MCP Python SDK.
- Secure HTTP defaults: loopback bind, DNS-rebinding protection, Host/Origin
  validation, body limits, bounded sessions/concurrency, optional bearer auth, and
  built-in OAuth 2.1 sign-in for hosted clients.
- Deterministic test suite with real MCP client tests for st…
