FOSS battlemap-mcp lets Claude Code and Codex drive Dungeondraft map editor
thekannenG · reddit · 2026-09-24
A new FOSS MCP project, battlemap-mcp, uses a GDScript mod serving an authenticated local socket inside Dungeondraft plus an MCP server, giving Claude Code or Codex tools for walls, floors, terrain, props, lights, levels, undo and screenshots. The author shares hard-won lessons: no try/catch in the engine's GDScript, colors settable only before placement, and a missing metadata piece silently breaking all saves. Cross-platform, open on GitHub.
