| Title | Breakpoint MCP | Breakpoint MCP |
| Description |
Breakpoint MCP exposes the live Godot editor — and, through an in-game runtime autoload, your running game — to an MCP (Model Context Protocol) host, so an AI assistant can drive Godot directly instead of guessing at your project from the outside. The addon runs a loopback-only TCP/JSON bridge on 127.0.0.1. Paired with its companion host (the "breakpoint-mcp" npm package, which your MCP client launches), it gives an assistant 242 tools across four capability planes: - Editor authoring: scene / node / resource CRUD, project settings, ClassDB introspection, and editor screenshots. Every mutation is wrapped in EditorUndoRedoManager, so anything the assistant changes is fully undoable. - In-game runtime bridge: inspect the live SceneTree, get/set properties, call methods, emit signals, inject input, and read Performance monitors while the game is running. - Language + debug: GDScript symbols, definitions, and completions via Godot's own Language Server, plus breakpoint debugging over the Debug Adapter Protocol. - Headless CLI: run and export projects. Requirements: Godot 4.2+ (4.4+ recommended — several editor tools use APIs added in 4.4; a few runtime-capture features use 4.5+). The host requires Node.js 18+. Works with any MCP-compatible client; developed and tested with Claude. Install: copy addons/breakpoint_mcp/ into your project (or install via the Asset Library), then enable it under Project > Project Settings > Plugins > Breakpoint MCP. On enable it listens on 127.0.0.1:9080. Point your MCP client at the breakpoint-mcp host — see the repository README for client setup. Security: the bridge binds to loopback only and handlers run on the editor main thread. Treat the port as a local trust boundary; do not expose it beyond 127.0.0.1. Open source under the MIT license. Full tool catalog, user guide, and configuration reference are in the repository. |
