**Connect MCP clients directly to a live Godot editor** via the [Model Context Protocol](https://modelcontextprotocol.io/introduction). Over **120 ops across ~39 MCP tools** ([full list](docs/TOOLS.md)) let AI assistants (Claude Code, Codex, Antigravity, etc.) build scenes, edit nodes and scripts, wire signals, and configure UI, materials, animations, particles, cameras, and environments.

> 🎉 **Now on the [Godot Asset Library](https://godotengine.org/asset-library/asset/5050) and the [new Godot Asset Store](https://store.godotengine.org/asset/dlight/godot-ai/)** — one-click install from Godot's **AssetLib** tab. You'll still need [uv](https://docs.astral.sh/uv/) for the Python server (see [Quick Start](#quick-start)).

</p>

---

## Quick Start

### Prerequisites

- Godot `4.3+` (`4.4+` recommended)
- [uv](https://docs.astral.sh/uv/) (for the Python server):
  - **macOS / Linux:** `curl -LsSf https://astral.sh/uv/install.sh | sh`
  - **Windows (PowerShell):** `powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"`
  - Other options: [uv install docs](https://docs.astral.sh/uv/getting-started/installation/)
- An MCP client ([Claude Code](https://docs.anthropic.com/en/docs/claude-code) | [Codex](https://openai.com/index/codex/) | [Antigravity](https://www.antigravity.dev/))

### 1. Install the plugin

**Recommended — install from source** (always the latest):

```bash
git clone https://github.com/hi-godot/godot-ai.git
cp -r godot-ai/plugin/addons/godot_ai your-project/addons/
```

Or [download the latest release ZIP](https://github.com/hi-godot/godot-ai/releases/latest) and extract `addons/godot_ai` into your project's `addons/` folder.

<details>
<summary>Or via the Godot Asset Library</summary>

In Godot, open the **AssetLib** tab, search for **Godot AI**, click **Download**, then **Install**. Note: Asset Library updates lag behind GitHub, so this version may not be the most recent.

> 🚨 **If installing from the Asset Library**, most issues can be resolved by disabling and re-enabling the plugin in **Project > Project Settings > Plugins**.

</details>

### 2. Enable the plugin

In Godot: **Project > Project Settings > Plugins** — enable **Godot AI**.

The plugin will automatically start the MCP server, connect over WebSocket, and show status in the **Godot AI** dock.

<p align="center"><img src="docs/images/dock.png" alt="Godot AI dock — Clients & Tools button highlighted" width="350"></p>

### 3. Connect your MCP client

The dock lists every supported client with a status dot and per-row
**Configure** / **Remove** buttons, or press **Configure all**. Auto-configure
covers:

- **Claude Code**, **Claude Desktop**, **Antigravity**

<details>
<summary><strong>…and 15+ more clients</strong></summary>

Codex, Cursor, Windsurf, VS Code, VS Code Insiders, Zed, Gemini CLI, Cline,
Kilo Code, Roo Code, Kiro, Trae, Cherry Studio, OpenCode, Qwen Code.

</details>

Server URL is always `http://127.0.0.1:8000/mcp`. If auto-configure can't find
a CLI, each dock row exposes a **Run this manually** panel with a copyable
snippet.

### 4. Try it

- *"Show me the current scene hierarchy."*
- *"Create a Camera3D named MainCamera under /Main."*
- *"Search the project for PackedScene files in ui/."*
- *"Run the scene test suite."*
- *"Build a voxel block-world game with a player, blocks to place and destroy, and save slots."*

**Tools and resources:** see [docs/TOOLS.md](docs/TOOLS.md) for the full list of 120+ MCP tools and resources, grouped by domain.

<details>
<summary><strong>Manual Client Configuration</strong></summary>

**Claude Code**

```bash
claude mcp add --scope user --transport http godot-ai http://127.0.0.1:8000/mcp
```

**Codex** (`~/.codex/config.toml`)

```toml
[mcp_servers."godot-ai"]
url = "http://127.0.0.1:8000/mcp"
enabled = true
```

**Antigravity** (`~/.gemini/antigravity/mcp_config.json`)

```json
{
  "mcpServers": {
    "godot-ai": {
      "serverUrl": "http://127.0.0.1:8000/mcp",
      "disabled": false
    }
  }
}
```

</details>

<details>
<summary><strong>How It Works</strong></summary>

```text
MCP Client
   | HTTP (/mcp)
   v
Python Server (FastMCP)      port 8000
   | WebSocket               port 9500
   v
Godot Editor Plugin
   | EditorInterface + SceneTree APIs
   v
Godot Editor
```

The plugin starts or reuses the Python server, connects over WebSocket, and exposes editor capabilities as MCP tools and resources over HTTP.

<details>
<summary><strong>Windows: <code>uvx mcp-proxy</code> won't start (<code>pywin32</code> install fails)</strong></summary>

Symptom (in your MCP client's server log):

```text
error: Failed to install: pywin32-311-cp313-cp313-win_amd64.whl (pywin32==311)
  Caused by: failed to remove directory `C:\Users\<you>\AppData\Local\uv\cache\builds-v0\.tmpXXXXXX\Lib\site-packages\pywin32-311.data`: ... os error 32
```

Cause: uv hard-links shared `.pyd` files (notably
`pydantic_core/_pydantic_core.cp313-win_amd64.pyd`) from `archive-v0\` into
each new `builds-v0\.tmpXXXXXX\` build venv. The running `godot-ai` Python
process has the same `.pyd` mapped via `LoadLibrary` — and because hard
links share the inode, Windows refuses to delete it under any path until
every process unmaps it. uv's post-install cleanup of the build venv then
dies on a stale lock; the misleading `pywin32` mention is just the last
package in the resolution order, not the actual lock holder.

**Mitigation in this plugin:**

1. `_stop_server` and `force_restart_server` both call
   `McpUvCacheCleanup.purge_stale_builds()` immediately after killing the
   server children, while the `.pyd` is briefly unmapped. See
   [`plugin/addons/godot_ai/utils/uv_cache_cleanup.gd`](plugin/addons/godot_ai/utils/uv_cache_cleanup.gd).
2. **Auto-configure now writes `UV_LINK_MODE=copy` into the bridged
   entry's `env` block** for every uvx-bridge client (Claude Desktop, Zed),
   telling uv to copy shared C extensions instead of hard-linking them.
   That removes the reverse race where an MCP client spawns `uvx mcp-proxy`
   *while* a server child still holds the `.pyd`. Existing entries written
   by older plugin versions surface in the dock as **drift (amber banner)**
   so a single Configure click rewrites them with the env pin.

The shape `client_configure` writes for Claude Desktop is now:

```json
{
  "mcpServers": {
    "godot-ai": {
      "command": "uvx",
      "args": ["mcp-proxy==0.11.0", "--transport", "streamablehttp", "http://127.0.0.1:8000/mcp"],
      "env": { "UV_LINK_MODE": "copy" }
    }
  }
}
```

If you've already hit the lock on an older config, click **Configure**
on the affected uvx-bridge client (Claude Desktop *or* Zed) in the
godot-ai dock to rewrite the entry with the env pin, then quit and
reopen that client. If the lock persists (rare — pre-existing orphans
the cache sweeper couldn't reach), kill stray `python.exe` children
whose command line contains `spawn_main(parent_pid=...)` and delete
`%LOCALAPPDATA%\uv\cache\builds-v0\.tmp*` manually before retrying.
