Title	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, authenticated with a per-project shared secret. Paired with its companion host (the "breakpoint-mcp" npm package, which your MCP client launches), it gives an assistant 293 tools — 280 with the higher-trust capability groups off by default — across four capability planes: - Editor authoring: scene / node / resource CRUD, project settings, ClassDB introspection, editor screenshots, and main-screen tab control (read which of 2D / 3D / Script / Game / AssetLib is active, and switch). 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 — plus deterministic playtesting (freeze time, step an exact number of frames, seed the RNG, and snapshot state for frame-by-frame comparison), live AnimationPlayer control, node spawn/despawn, an await-condition helper, and a read-only verification family (assert node / scene / on-screen-text / performance state, and screenshot diffs). - Language + debug (GDScript and C#): symbols, definitions, completions, and diagnostics via Godot's own Language Server (and OmniSharp for C#), plus real breakpoint/step debugging over the Debug Adapter Protocol (and netcoredbg for C#). - Headless CLI: run, export, import, and run headless tests; long jobs use the MCP task model. Human-in-the-loop control: destructive tools are confirmation-gated, the higher-trust tools sit in default-off capability groups, and a one-click "Pause Agent" toggle in the editor dock lets you hold the assistant's actions on demand. Nothing on the tool surface reaches past loopback. 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 and auto-registers the in-game runtime autoload, which opens its port only when the game is started from an editor build. Point your MCP client at the breakpoint-mcp host — see the repository README for client setup. Security: the bridges bind to loopback only, require a per-project shared secret, and handlers run on the main thread. Exported games keep the runtime bridge closed: no port, no files written (since addon 1.17.0 — if you exported a game with an earlier version and the plugin enabled, update and re-export). Treat the ports as a local trust boundary; do not expose them beyond 127.0.0.1. Open source under the MIT license. Full tool catalog, user guide, and configuration reference are in the repository.
