pitstop-f1

Pitstop — F1 MCP Server

An HTTP-first Model Context Protocol (MCP) server for Formula 1 data. Aggregates real-time, historical, and news data from multiple authoritative sources into 11 tools ready for any MCP client.

v0.5.0 | Author: Praneeth Ravuri

Install

stdio, via uvx (no clone needed):

PITSTOP_TRANSPORT=stdio uvx pitstop-f1

Via the Claude Code CLI:

claude mcp add pitstop -e PITSTOP_TRANSPORT=stdio -- uvx pitstop-f1

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "pitstop": {
      "command": "uvx",
      "args": ["pitstop-f1"],
      "env": { "PITSTOP_TRANSPORT": "stdio" }
    }
  }
}

Docker (HTTP transport, runs the full server incl. the F1 database):

docker compose up
# → http://localhost:8000/mcp

Overview

Pitstop exposes F1 data as 11 MCP tools over HTTP (default) or stdio. It pulls from FastF1, Jolpica, OpenF1, Wikidata, RSS feeds, and its own seeded F1 database, handling pagination, retries, caching, and concurrency limits transparently.

Data Sources

Source	Coverage	Type
FastF1	2018–present	Historical / timing / telemetry
Jolpica-F1	1950–present	Historical (Ergast-compatible)
OpenF1	2023–present	Real-time
Wikidata	All eras	SPARQL queries
RSS Feeds (20 sources)	Live	News
Pitstop F1 Database	1950–present	Owned sqlite (seeded from F1DB, self-updated weekly from Jolpica) + per-lap times

Database refresh: .github/workflows/db-update.yml runs weekly to pull new Jolpica results into the owned F1 database.

Transport

HTTP (default)

uv sync
uv run pitstop
# → http://localhost:8000

MCP client config:

{
  "mcpServers": {
    "pitstop": {
      "type": "http",
      "url": "http://localhost:8000/mcp"
    }
  }
}

stdio (opt-in)

PITSTOP_TRANSPORT=stdio uv run pitstop

MCP client config:

{
  "mcpServers": {
    "pitstop": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/pitstop", "pitstop"],
      "env": { "PITSTOP_TRANSPORT": "stdio" }
    }
  }
}

Health API

Endpoint	Purpose
GET /health	Per-source status (FastF1, f1db, Jolpica, OpenF1, RSS)
GET /live	Liveness probe
GET /ready	Readiness probe

Example /health response:

{
  "version": "0.5.0",
  "overall": "ok",
  "sources": [
    { "name": "fastf1",  "status": "ok", "latency_ms": 2,   "detail": "cache writable" },
    { "name": "f1db",    "status": "ok", "latency_ms": 1,   "detail": "" },
    { "name": "jolpica", "status": "ok", "latency_ms": 134, "detail": "" },
    { "name": "openf1",  "status": "ok", "latency_ms": 98,  "detail": "" },
    { "name": "rss",     "status": "ok", "latency_ms": 210, "detail": "" }
  ]
}

overall is "ok" / "degraded" / "down". HTTP 200 / 207 / 503.

Wikidata SPARQL

query_wikidata runs SPARQL queries against Wikidata for biographical and historical F1 facts not covered by race APIs.

Only SELECT and ASK queries are accepted (read-only). Always include LIMIT in your query.

Example — find F1 drivers with their birthdate:

SELECT ?driver ?driverLabel ?birthDate WHERE {
  ?driver wdt:P31 wd:Q5 ;
          wdt:P641 wd:Q1968 ;
          wdt:P569 ?birthDate .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
} ORDER BY DESC(?birthDate) LIMIT 10

Pagination

All list-returning tools accept page (1-based, default 1) and page_size (defaults vary per tool: 10–50). Responses include a pagination block:

{
  "data": [...],
  "pagination": {
    "page": 1,
    "page_size": 20,
    "total_items": 47,
    "total_pages": 3,
    "has_next": true,
    "has_prev": false
  }
}

Configuration

Variable	Default	Description
PITSTOP_TRANSPORT	http	http or stdio
PITSTOP_HOST	0.0.0.0	Bind address (HTTP only)
PITSTOP_PORT	8000	Listen port (HTTP only)
PITSTOP_ENV	development	development or production
PITSTOP_LOG_LEVEL	Depends on PITSTOP_ENV	DEBUG if development, else INFO
PITSTOP_LOG_FORMAT	Depends on PITSTOP_ENV	text if development, else json
PITSTOP_ENABLE_CACHING	true	Enable HTTP response and FastF1 disk caching
PITSTOP_CACHE_TTL_SECONDS	300	HTTP response cache time-to-live (seconds)
PITSTOP_RATE_LIMIT_ENABLED	false	Enable concurrent-call limiting
PITSTOP_RATE_LIMIT_PER_HOUR	3600	Max concurrent calls (derived from per-hour quota)
FASTF1_CACHE	cache	FastF1 cache directory path

Caching

Pitstop uses in-memory HTTP response caching (via Hishel) for GET requests with 200 responses. This keeps tool calls inside upstream rate limits:

• Jolpica: 4 req/s, 500/hr
• OpenF1: 3 req/s, 30/min
• Wikidata: Query complexity limits
• RSS: Per-feed redirects cached

FastF1 maintains its own disk cache in FASTF1_CACHE directory. Control caching via:

• PITSTOP_ENABLE_CACHING=true (default)
• PITSTOP_CACHE_TTL_SECONDS=300 (default)

Development

uv sync --dev
uv run pytest
uv run ruff check src/
