# Game reference

> Generated from the game: MCP tools, data files, tuning and flags.

<!-- Generated by `zombye-server --docs`. Do not edit: change the game and generate again. -->

These pages are written by the game itself (`zombye-server --docs`), from its own tool list, data files, settings and source, so they always match the build they came from. Nothing here is typed out by hand.

Generated from game build `0ed42dd`.

- [MCP tools](/docs/reference/game/mcp-tools/): all 68 tools an agent can call, with their arguments.
- [Tuning](/docs/reference/game/tuning/): every gameplay number not in a data file, with its shipped value.
- [Command-line flags](/docs/reference/game/cli/): the game's and the server's.
