GladeKit MCP
Connect Cursor, Claude Code, Windsurf, Claude Desktop, and other AI clients directly to your Unity or Godot editor.
Unity (2021.3+): 275 tools across 20 categories, full Unity-aware system prompt, GLADE.md project context, script semantic search, skill calibration, free CC0 asset pipeline, cloud intelligence layer with RAG and cross-session memory.
Godot (4.3+): 115 native tools across 17 categories - scene/node, scripts, resources, signals, physics and edit-time spatial queries, 2D (sprites, tilemaps, parallax), audio, particles, animation and AnimationTree, camera, navigation, UI, lighting and WorldEnvironment, runtime, export, and project introspection.
Both engines: one-call vetted gameplay scaffolders (controllers, enemies, combat, menus, save system), a verification loop (look_at_game_view screenshots, runtime-event observation, playability probes), surgical script editing with true find_references / rename_symbol, and build/export tools so the agent can ship what it built.
The MCP server auto-detects which editor is running (Unity on :8765, Godot on :8766) and exposes the matching tool set.
Quick Start
1. Install the editor bridge
GladeKit MCP supports both Unity and Godot. Both bridges live in this repo: unity-bridge/ is a UPM package, godot-bridge/ wraps the editor addon at godot-bridge/addons/com.gladekit.mcp-bridge/. Install the one for your engine.
Engine auto-detection: the MCP server probes both ports on startup and exposes the matching tool set. Running both editors at once? Set GLADEKIT_MCP_FORCE_ENGINE=unity or =godot to pin a specific engine.
2. Connect your AI client
Install uv (one-time):
- Mac/Linux:
curl -LsSf https://astral.sh/uv/install.sh | sh - Windows:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
Then add the MCP config to your AI client. The client launches the MCP server automatically - no manual server step.

None | None |
| Safety | Undo-registered edits, pre-mutation backups, overwrite guards, per-session token auth, read-only mode | SHA-guarded script edits | None |
| Tests | 269 pytest + 37-case eval on 3 MCP SDK versions, schema↔bridge parity guards, Unity NUnit + Godot GUT suites | Unity CI matrix + NL suite | None |

Verified against the unity-mcp v10.1.2 and godot-mcp 0.1.1 sources on 2026-08-29. godot-mcp is the most-starred Godot server; the closest active in-editor alternative, godot-ai (46 tools), has screenshots and batch execution but no scaffolders, refactoring, asset pipeline, export, or memory.
All core features are free and local. The cloud intelligence layer is optional and requires a GLADEKIT_API_KEY.

The GladeKit desktop app is a separate commercial product that layers streaming, miss recovery, and a memory UI on top of this MCP server.
