Warhammer 40K and Kill Team rules, stats, and game flow MCP server
Warhammer MCP server exists for a simple reason — assistants are far more useful when they can act on Warhammer directly instead of describing what you should do. Warhammer 40K and Kill Team rules, stats, and game flow MCP server.
The server ships on npm as warhammer-oracle, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once Warhammer is connected, these are the calls the assistant has available:

Warhammer's toolset — lookup_unit, lookup_keyword, lookup_phase and 11 more — is a fair guide to whether it matches your workflow. It is maintained by gregario; worth a glance at recent repository activity before you build anything load-bearing on it.
