Pitstop

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

Hosted endpoint (nothing to install)

A free public instance runs on Hugging Face Spaces:

https://praneeth1025-pitstop.hf.space/mcp

claude mcp add --transport http pitstop https://praneeth1025-pitstop.hf.space/mcp

Note: the Space sleeps after long inactivity — the first request after a quiet spell takes a cold start.

Local install

stdio, via uvx (no clone needed):

PITSTOP_TRANSPORT=stdio uvx pitstop-f1

Claude Code:

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

Codex CLI:

codex mcp add pitstop --env PITSTOP_TRANSPORT=stdio -- uvx pitstop-f1

Gemini CLI:

gemini mcp add pitstop uvx pitstop-f1 --env PITSTOP_TRANSPORT=stdio

VS Code:

code --add-mcp '{"name":"pitstop","command":"uvx","args":["pitstop-f1"],"env":{"PITSTOP_TRANSPORT":"stdio"}}'

Claude Desktop (claude_desktop_config.json), Cursor (~/.cursor/mcp.json), and Windsurf (~/.codeium/windsurf/mcp_config.json) share the same JSON shape:

{

"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

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

---

Tools

---

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

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

---

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)
