Glade

Glade 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

Glade 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.

In Unity, open Window > Package Manager > + > Add package from git URL...

https://github.com/Glade-tool/glade-mcp.git?path=/unity-bridge

The Unity bridge starts automatically on localhost:8765. Window > GladeKit MCP shows bridge / client status and has one-click Copy MCP Config and Copy Unity AI Gateway Config buttons.

1. Download com.gladekit.mcp-bridge.zip from the latest Godot bridge release. (Grab the zip asset under Assets - not "Source code".) From source instead: copy godot-bridge/addons/com.gladekit.mcp-bridge/ out of this repo.
2. Move the com.gladekit.mcp-bridge/ folder into your project's addons/ directory, so the final path is <your-godot-project>/addons/com.gladekit.mcp-bridge/plugin.cfg.
3. In Godot: Project → Project Settings → Plugins → enable GladeKit MCP Bridge.

The Godot bridge starts automatically on localhost:8766. You should see a confirmation line in the editor Output panel:

[GladeKit MCP Bridge] listening on ws://127.0.0.1:8766  (v0.7.13, 115 tools registered, thread-polled at 200Hz)

The bridge writes a per-session auth token to ~/.gladekit/godot-bridge-8766.token; the MCP server picks it up automatically, so a web page can't drive your editor through the local socket.

Supported: Godot 4.3+ GDScript projects, Forward+ and Compatibility renderers, 2D and 3D. Not yet supported: Godot Mono / C# projects. The bridge is editor-only; it never runs in exported games.

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.

Option A: one-liner (recommended)

• Mac/Linux: claude mcp add --transport stdio gladekit-mcp --scope user -- uvx gladekit-mcp
• Windows: claude mcp add --transport stdio gladekit-mcp --scope user -- cmd /c uvx gladekit-mcp

Option B: manual config

If you cloned this repo, the .mcp.json auto-connects. Otherwise add to your Claude Code MCP settings:

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",
      "args": ["gladekit-mcp"]
    }
  }
}

Cursor Settings > MCP > Add new MCP server:

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",
      "args": ["gladekit-mcp"]
    }
  }
}

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",
      "args": ["gladekit-mcp"]
    }
  }
}

Open Cline's MCP settings file (auto-created on first MCP use):

• Mac: ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
• Windows: %APPDATA%\Code\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json
• Linux: ~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json

Add:

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",
      "args": ["gladekit-mcp"]
    }
  }
}

In Windsurf, open Windsurf Settings → MCP Servers → Open MCP Registry, then click the settings (gear) icon to open mcp_config.json. Add the snippet below (or edit ~/.codeium/windsurf/mcp_config.json directly):

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",
      "args": ["gladekit-mcp"]
    }
  }
}

Unity's built-in AI Assistant can connect to GladeKit via MCP. This gives you GladeKit's 275 tools directly inside the Unity Editor - no external AI client needed.

Requires: Unity 6000.3+ with AI Gateway package ([email protected])

1. In Unity, go to Edit > Project Settings > AI > MCP Servers
2. Click Open Config File and paste (or use Window > GladeKit MCP > Copy Unity AI Gateway Config):

{
  "enabled": true,
  "path": "",
  "mcpServers": {
    "gladekit-mcp": {
      "type": "stdio",
      "command": "uvx",
      "args": ["gladekit-mcp"]
    }
  }
}

3. Under Path Configuration, paste your terminal's PATH into User Path so Unity can find uvx. To get your PATH:
   • Mac/Linux: echo $PATH
   • Windows: echo %PATH%
4. Click Refresh Config File and Reload Servers
5. Verify the server shows StartedSuccessfully in the Servers section

Tip: If uvx isn't found, add the directory containing it to the path field in the config (e.g., "/opt/homebrew/bin" on Mac or "C:\\Users\\<you>\\.local\\bin" on Windows). Alternatively, use pip install gladekit-mcp and set "command": "python" with "args": ["-m", "gladekit_mcp"].

Troubleshooting: If the server shows FailedToStart, click Inspect for error details. The most common cause is PATH - Unity's PATH differs from your terminal's PATH. See the Troubleshooting section below.

Paid tier (GLADEKIT_API_KEY): To enable RAG knowledge base and cross-session memory on any client, add the key to the env field of your config. See Cloud intelligence below.

Add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "gladekit-mcp": {
      "type": "stdio",
      "command": "uvx",
      "args": ["gladekit-mcp"]
    }
  }
}

Why GladeKit?

All core features are free and local. The cloud intelligence layer is optional and requires a GLADEKIT_API_KEY.

Features

Unity (20 categories): Scene • GameObjects • Scripts • Prefabs • Materials • Lighting • VFX & Audio • Animation • IK • Physics (3D & 2D) • Tilemaps • Camera • UI • Input System • Terrain & NavMesh • Profiler • Gameplay scaffolders • Runtime & diagnostics • Build • Asset pipeline

All 275 tools are dispatchable. Claude Code sees ~90 curated core tools by default (Claude Code has a practical 128-tool limit; Unity AI Gateway has a cloud token budget). Use get_relevant_tools to discover extended tools for specialized work (blend trees, NavMesh, IK, Cinemachine, etc.).

5 meta-tools: get_relevant_tools (task-based tool discovery + RAG context), remember_for_session (store facts), recall_session_memories (retrieve facts), batch_execute (multi-step tool dispatch), search_project_scripts (semantic code search, Unity only). The first four work on both engines.

9 MCP resources (Unity): bridge health, project context, project info, scene hierarchy, project scripts, current selection, GLADE.md, session memory, and batch-discipline telemetry.

Godot (17 categories): all 115 tools are exposed directly (no core filtering needed), plus the four engine-agnostic meta-tools. Read-only tools carry the MCP readOnlyHint annotation so clients can auto-approve them.

Vetted, self-wiring templates that write known-good scripts verbatim and assemble the scene around them - carrying the game-feel details a from-scratch script tends to drop (coyote time, jump buffering, variable jump height, normalized diagonals). Re-running one reuses what already exists instead of duplicating it.

• Players: create_third_person_controller (3D, both engines), create_platformer_controller / create_top_down_controller (Unity), create_2d_controller (Godot).
• Combat: create_projectile, create_health, create_health_bar, create_enemy (Unity) / create_enemy_2d + create_enemy_3d (Godot), create_hit_vfx.
• Game loop: create_game_manager (score, lives, win/lose), create_collectible, create_hazard, create_level_system, create_loot_drop, create_save_system.
• Flow and feel: create_main_menu, create_pause_menu, create_scene_transition, create_moving_platform, create_screen_shake, create_juice, create_particles_2d / _3d, create_sound_effects.

Batch layout tools (set_transform_batch, set_node_transform_batch, arrange_nodes, snap_to_ground) place dozens of objects in one call instead of one round-trip each.

• See it: look_at_game_view returns a screenshot of the rendered view so the model catches invisible, missing, or mispositioned objects that inspection alone cannot.
• Watch it run: start_runtime_observation / get_runtime_events stream a cursored, fingerprinted error feed from the play session; get_unity_console_logs / get_godot_console_logs for the raw log.
• Play-test it: start_playability_probe (Unity) and run_gameplay_probe (Godot) drive the player with input and report PASS/FAIL; Godot's run_project has a verify mode that runs, captures, and reports.
• Compile and ship it: compile_scripts (Unity); build_player + get_build_status (Unity) and create_export_preset + export_project (Godot, including Web).
• Diagnose stalls (Godot): an editor main-thread watchdog turns "timed out" into "editor wedged for 12s - dismiss the modal dialog" with possible_solutions.

get_script_content supports outline mode (a structural map of a large file) and line-ranged partial reads; modify_script applies anchor-based edits. find_references and rename_symbol use a lexical scanner (C# and GDScript) that matches whole identifiers only, so a rename shows its real blast radius before it happens. create_script / modify_script refuse to clobber existing project scripts unless asked.

Create a GLADE.md file in your Unity project root. The MCP server reads it and injects it into every request. Works as a permanent context layer: your game's design intent, conventions, and constraints are always in scope.

# My Game

Genre: 3D platformer
Player: CharacterController, double jump enabled
Art style: pixel art, 16x16 sprites
Naming: PascalCase for scripts, snake_case for folders

Set OPENAI_API_KEY in your MCP config's env field and the server ranks project scripts by semantic similarity to your query. Ask "how does the enemy spawn?" and the right script surfaces, even if it's not named EnemySpawner.

Everything needed ships with the package; no install flags or extras required. Get a key at platform.openai.com/api-keys (pay-as-you-go, pennies per search via text-embedding-3-small).

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",
      "args": ["gladekit-mcp"],
      "env": { "OPENAI_API_KEY": "sk-..." }
    }
  }
}

Without the key, search_project_scripts still returns scripts - just unranked. Keys are never sent anywhere except OpenAI's embedding endpoint.

The server tracks vocabulary across your messages and detects whether you're a Unity beginner or expert. Beginners get plain-language explanations and encouraging framing. Experts get terse, technical responses. Calibration persists to .gladekit/skill_level.json in your project.

Three tools for finding and importing free, commercially-usable assets directly from your AI client, on both engines. All assets are CC0 (public domain, no attribution required). v1 ships Kenney.nl packs (catalog refreshed weekly); additional providers (Freesound, Quaternius, AI generation) are on the roadmap.

Example workflow (Cursor, Claude Code, Windsurf use the same pattern):

You: I'm prototyping a 2D platformer and need placeholder character + tile art. Find me something free.

The AI calls find_asset:

{
  "description": "platformer character and tiles",
  "asset_type": "sprite_2d",
  "max_results": 5
}

Result (truncated):

{
  "success": true,
  "candidates": [
    {
      "id": "kenney/platformer-pack-redux",
      "name": "Platformer Pack Redux",
      "description": "360+ side-scrolling platformer sprites: characters, enemies, tiles, items, hazards.",
      "license": "CC0-1.0",
      "license_summary": "Public domain. No attribution required for any use, including commercial.",
      "official_page": "https://kenney.nl/assets/platformer-pack-redux",
      "approx_assets": 360,
      "score": 0.92
    },
    { "id": "kenney/pixel-platformer", "score": 0.71, ... },
    { "id": "kenney/tiny-town", "score": 0.45, ... }
  ],
  "count": 3
}

You: Let's go with Platformer Pack Redux. Import it to Assets/Sprites/Platformer/. I accept the CC0 license.

The AI calls import_asset:

{
  "candidateId": "kenney/platformer-pack-redux",
  "assetType": "sprite_2d",
  "licenseAcknowledged": true,
  "targetPath": "Assets/Sprites/Platformer/"
}

The MCP server resolves the download URL locally (catalog is bundled with the server, no cloud dependency), passes it to the Unity bridge, which downloads, extracts, configures TextureImporter for each sprite (Texture Type = Sprite, Filter Mode = Point, Uncompressed) and writes the license sidecar. Result:

{
  "success": true,
  "message": "Imported 360 file(s) from kenney/platformer-pack-redux to Assets/Sprites/Platformer/",
  "downloadedBytes": 1842340,
  "importedFileCount": 360,
  "configuredImportSettings": 354,
  "license": "CC0-1.0",
  "sidecarPath": "Assets/Sprites/Platformer/.gladekit-asset.json"
}

The sprites appear in the Unity Project window, ready to drop into a scene.

You: Before I ship, audit my imported assets. Anything that needs attribution?

The AI calls list_imported_assets:

{
  "success": true,
  "count": 1,
  "licenseCounts": { "CC0-1.0": 1 },
  "attributionRequiredCount": 0,
  "entries": [
    {
      "candidate_id": "kenney/platformer-pack-redux",
      "license": "CC0-1.0",
      "asset_type": "sprite_2d",
      "imported_at": "2026-05-10T09:37:42Z",
      "target_path": "Assets/Sprites/Platformer/",
      "imported_file_count": 360,
      "sidecar_path": "Assets/Sprites/Platformer/.gladekit-asset.json"
    }
  ]
}

CC0 needs no attribution; the audit report is empty for required attributions. If you imported a CC-BY asset later, it would surface here so you remember to credit it.

Security and license discipline:

• The LLM never sees download URLs. URL resolution happens cloud/MCP-side; the bridge tool refuses if the resolved fields are missing or LLM-injected.
• licenseAcknowledged: true is required on every import_asset call. The bridge refuses without it. Do not set it without explicit user confirmation.
• The bridge validates _resolvedUrl's host against a per-provider allowlist (AssetPipelineGuard.IsResolvedUrlHostAllowed) before downloading. Even a client bypassing both the cloud and MCP preprocessors cannot smuggle in an arbitrary download URL; unknown hosts fail closed. HTTPS only.
• Every imported asset bundle gets a .gladekit-asset.json sidecar recording the candidate id, provider, license, attribution string, source URL, and timestamp. list_imported_assets reads these for the audit report.
• Asset Pipeline tools are gated by AssetPipelineGuard on the bridge side. A misconfigured client cannot bypass it.

Disabling the pipeline (for studio / curated-asset workflows):

Set GLADEKIT_MCP_DISABLE_ASSET_PIPELINE=1 in the MCP server's environment to suppress the three tools entirely. They will not appear in the tool list and dispatch will refuse with a clear error. This is the recommended setting for projects that already have a managed asset workflow (Perforce-tracked libraries, internal asset stores) where AI-driven external downloads aren't appropriate.

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",
      "args": ["gladekit-mcp"],
      "env": { "GLADEKIT_MCP_DISABLE_ASSET_PIPELINE": "1" }
    }
  }
}

The Unity bridge enforces the same gate via EditorPrefs (GladeAI.AssetPipelineEnabled, default true). Toggle it via POST http://localhost:8765/api/settings { "assetPipelineEnabled": false }.

• Reversible: scaffolds and batch edits register with the editor's Undo stack (Unity) or take pre-mutation backups in .gladekit-backups/ with node revert (Godot). create_script / modify_script refuse to overwrite real project scripts without an explicit flag.
• Loopback only: both bridges bind 127.0.0.1. The Godot bridge requires a per-session token (~/.gladekit/godot-bridge-<port>.token) on every request except health, closing the cross-site WebSocket drive-by. The Unity bridge enforces localhost access control and path-traversal guards on its file endpoints.
• Play-mode safety: editing tools refuse to run while the editor is playing; read-only tools run in either mode.
• Read-only sessions: GLADEKIT_GODOT_READ_ONLY=1 (or gladekit/read_only_mode in project settings) makes the Godot bridge refuse every mutating tool - for audits, reviews, and demos.

Set GLADEKIT_API_KEY in your MCP config's env field to unlock cloud-powered features:

• RAG knowledge base - get_relevant_tools queries a curated, engine-aware knowledge base (API corrections, error patterns) and injects results alongside tool recommendations. Godot sessions retrieve Godot docs, not Unity content.
• Cross-session persistent memory - facts stored with remember_for_session persist across sessions and are re-injected into the system prompt.
• Convention extraction - coding patterns (naming, architecture, preferences) are distilled from your accumulated memories and surfaced in future sessions.

All cloud features degrade gracefully: if the key is missing or the cloud is unreachable, everything works normally.

{
  "mcpServers": {
    "gladekit-mcp": {
      "command": "uvx",

    }
  }
}

GladeKit MCP supports two transports. stdio is the default and works with all MCP clients - every config above uses stdio. The server supports both MCP SDK 1.x and 2.x (mcp[cli]>=1.10,<3) and is tested at the floor, the newest 1.x, and the newest 2.x.

Streamable HTTP is for clients that prefer URL-based config (Claude Desktop URL mode, custom clients). Launch the server manually, then point your client at the URL:

# Defaults: host=127.0.0.1, port=8767, path=/mcp
gladekit-mcp --transport http

# Custom host/port/path
gladekit-mcp --transport http --host 127.0.0.1 --port 9000 --path /mcp

Endpoints:

• POST/GET/DELETE http://127.0.0.1:8767/mcp - MCP streamable-HTTP endpoint
• GET http://127.0.0.1:8767/health - liveness check

Security defaults:

• Binds loopback-only (127.0.0.1). Use --host 0.0.0.0 to expose on LAN - opt-in only.
• DNS-rebinding protection enabled for loopback binds: requests with a Host header other than 127.0.0.1:<port> or localhost:<port> are rejected with 421 Misdirected Request.
• Non-loopback binds disable rebinding protection (you've taken responsibility for the network) and print a warning on startup.

Client config example:

{
  "mcpServers": {
    "gladekit-mcp": {
      "url": "http://127.0.0.1:8767/mcp"
    }
  }
}

MCP server (set in your client config's env field):

Godot bridge (set in your shell before launching Godot):

Unity bridge not connecting

• Open Unity and wait for it to finish importing assets - the bridge starts automatically
• Check Window > GladeKit MCP in Unity - the Bridge and AI Client indicators show connection status; Restart rebinds the server and the Diagnostics panel shows recent bridge faults
• Verify nothing else is using port 8765: lsof -i :8765 (Mac/Linux) or netstat -ano | findstr 8765 (Windows)

Godot bridge not connecting

• Confirm the plugin is enabled and the Output panel shows the listening on ws://127.0.0.1:8766 line; a bind failure prints the GLADEKIT_GODOT_BRIDGE_PORT override instructions
• authentication failed in tool errors: the MCP server couldn't read ~/.gladekit/godot-bridge-8766.token. Restart Godot (it rewrites the token) or, for an older client, set GLADEKIT_GODOT_NO_AUTH=1 before launching Godot
• Tool calls time out while a dialog is open: the editor's main thread is blocked. Dismiss the dialog; the error names the stall duration

AI client can't find uvx

• Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh (Mac/Linux) or pip install uv
• Or use pip install gladekit-mcp and change the config command from "uvx" to "python" with args ["-m", "gladekit_mcp"]

Tools not appearing in Claude Code

• Claude Code has a practical ~128-tool limit. GladeKit shows ~90 curated core tools by default - this is intentional. All 275 are dispatchable: use get_relevant_tools to find extended tools by task description.

GLADE.md not being picked up

• The file must be named exactly GLADE.md (case-sensitive on Mac/Linux) and placed in the Unity project root (same directory as Assets/, Packages/, ProjectSettings/)

Stderr warning: Unity bridge X.Y.Z is older than recommended

• Unity caches UPM git packages and never refetches, so an ?path=unity-bridge install drifts behind main over time. Update via Unity → Window > Package Manager > GladeKit MCP Bridge > Update, or pin the manifest entry to a specific tag so future updates are explicit:

  "com.gladekit.mcp-bridge": "https://github.com/Glade-tool/glade-mcp.git?path=unity-bridge#v0.7.23"
  

• The same warning also appears as a one-shot prefix on the next tool response so you see it in chat. To silence both: add "GLADEKIT_MCP_SUPPRESS_BRIDGE_WARNING": "1" to the env of your MCP client config. For Godot, replace the addon folder with the latest release zip.

Unity AI Gateway - server shows FailedToStart

• Click Inspect in the Servers section for the error message
• Most common cause: Unity can't find uvx. Under Path Configuration, paste your terminal's full PATH into User Path, then click Refresh Config File and Reload Servers
• On Windows: echo %PATH% in Command Prompt. On Mac/Linux: echo $PATH
• Alternative: use pip install gladekit-mcp and set the command to "python" with args ["-m", "gladekit_mcp"] - avoids the uvx PATH dependency
• Validate outside Unity first: run uvx gladekit-mcp in a terminal (you should see the gladekit-mcp v... banner on stderr)

Each bridge is the source of truth for its tools; the Python server mirrors the schema. CI (ruff + pytest + the eval harness, on three MCP SDK versions) runs on every change to mcp-server/, unity-bridge/, or godot-bridge/, and a schema↔bridge field-parity test fails if an argument exists on one side only. Adding a tool takes three changes.

Unity

1. C# implementation (unity-bridge/Editor/Tools/Implementations/<Category>/MyTool.cs):

public class MyTool : ITool
{
    public string Name => "my_tool";
    public string Execute(Dictionary<string, object> args)
    {
        // ... Unity Editor API calls ...
        return ToolUtils.CreateSuccessResponse("Done", extras);
    }
}

2. C# registration (unity-bridge/Editor/Tools/Registrars/<Category>Tools.cs): add Register(new MyTool());. Registration is explicit — an unregistered tool compiles fine but returns "Tool was blocked from executing or null." when dispatched.

3. Python schema (mcp-server/src/gladekit_mcp/tools/<category>.py): add an entry to the category's tool list following the existing format (OpenAI function-calling schema).

Godot

1. GDScript implementation (godot-bridge/addons/com.gladekit.mcp-bridge/tools/implementations/<category>/my_tool.gd) extending i_tool.gd; set tool_name and requires_edit_mode in _init() and return ToolUtils.success(...) / ToolUtils.error(...).

2. Registration in godot-bridge/addons/com.gladekit.mcp-bridge/bridge/tool_registry.gd (register_tool(MyTool.new())).

3. Python schema (mcp-server/src/gladekit_mcp/schemas/godot/<category>.py).

See godot-bridge/README.md for the wire protocol and GUT test setup, and mcp-server/CHANGELOG.md for release history.
