MCP server
Ask for results in plain English from Claude, ChatGPT, Cursor or Claude Code.
The MCP server puts the API in front of an assistant as tools. The address is https://horseracingapi.org/mcp.
Claude and ChatGPT
Add a custom connector with that address. You sign in with your HorseRacingAPI account once; there is no key to paste. Your plan applies as it does to the API.
Cursor and Claude Code
Add the server with your key in a header:
claude mcp add --transport http horseracingapi https://horseracingapi.org/mcp --header "X-API-Key: hra_live_…"An example
Ask "Who won the Derby at Epsom in 2024, and what has the winner done since?" The assistant calls search_races, then get_race, then horse_form, and answers with the result and the last runs.
Every tool is listed on MCP tools.
