A model context protocol server to chat with iRacing data.
A model context protocol server to chat with iRacing data. The iracing mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 2 defined tools rather than through you.
iRacing MCP is a Python-based project that integrates iRacing with the Model Context Protocol (MCP). It provides tools and resources to interact with iRacing data and build custom applications.
Everything the assistant can do here goes through one of these:
Prerequisites — The Prerequisites tool exposed by this serverDevelopment — The Development tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at iracing-mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
You will need 2 environment variables: IRACING_USERNAME, IRACING_PASSWORD. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. IRacing MCP's toolset — Prerequisites, Development — is a fair guide to whether it matches your workflow. It is maintained by musantro; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
