Carspeed MCP server

Carspeed publishes a public Model Context Protocol (MCP) server so AI assistants — ChatGPT, Claude, Cursor, Codex, and any MCP-compatible client — can search the car database, compare vehicles, and simulate drag races.

Endpoint

https://carspeed.co/mcp

Transport: MCP Streamable HTTP (spec 2025-06-18). No authentication required — the server is public and read-only.

Tools

search_cars

{
  "query": "string",
  "limit": "number (1-10, default 5)"
}

compare_cars

Compare two cars on 0-60, 0-100, top speed, horsepower, and price. Returns per-metric winners (or 'tie'), both cars' specifications, and a matchup URL plus an interactive drag-race URL.

{
  "car_a": "string",
  "car_b": "string"
}

simulate_drag_race

Simulate a drag race over a chosen distance (default 402 m). Returns finish times, gap, winner, and an interactive animation URL. result_type is 'simulated_from_specs'.

{
  "car_a": "string",
  "car_b": "string",
  "distance_m": "number (50-2000, default 402)"
}

top_cars

Rank cars by 0-60, top speed, horsepower, or price. Optional make filter.

{
  "metric": "'zero_to_60' | 'top_speed' | 'horsepower' | 'cheapest'",
  "company": "string?",
  "limit": "number (1-10, default 5)"
}

trending_matchups

Return the currently most-raced head-to-head matchups on Carspeed.

Response fields

Every tool response includes the following URL and provenance fields where relevant, so assistants can link users to the underlying source and downstream systems can distinguish simulated from observed data:

source_url — canonical page on carspeed.co the response is derived from.
details_url — per-car page with the full spec sheet.
matchup_url — head-to-head page for two cars.
interactive_race_url — deep link to the browser drag-race animation.
methodology_url — /methodology.
data_source — always "manufacturer_published_specs".
last_updated — ISO date of the dataset revision.
result_type (drag-race only) — always "simulated_from_specs".

Absent metric fields are omitted from responses rather than returned as null.
