This one needs environment variables set before it will start: DFHACK_HOST (Host running DFHack's remote RPC server. Defaults to 127.0.0.1.), DFHACK_PORT (Port for DFHack's remote RPC server. Defaults to 5000.), DFHACK_MCP_ACTUATORS (Set to any value to expose the write tools. Unset, the server is read-only.). The author declared them in the registry entry; get the values from the project itself.

Dwarf Fortress (DFHack) — questions

Answers built from our own checks of this server.

Why is there no uptime for Dwarf Fortress (DFHack)?

Dwarf Fortress (DFHack) runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package dfhack-mcp was installed 64 times last week.

How do I connect Dwarf Fortress (DFHack)?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls dfhack-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Dwarf Fortress (DFHack)?

The npm package dfhack-mcp was installed 64 times in the last week. Week over week that is -86%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Dwarf Fortress (DFHack) open source?

Yes — it is published under the ISC licence, written in Lua, 1 stars on GitHub and 16 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
