hmc-mcp-bridge

headlessmc-mcp is a MCP server that allows your AI agent control Minecraft servers, clients, etc. You can e.g. open Claude, tell it to launch a paper server and to connect to it with a fabric client that uses your mod. Claude can then debug if everything is okay with your mod, the server and the client, helping you with developing your mods/modpacks.

This is a bridge mod that provides a connection for MCP servers to the Minecraft client. It uses the hmc-specifics API to support almost all major versions from 1.7.10 – 26.3. If you start your game with this mod and you open an Agent session later, that session can connect to your game and control it.
