+# MCP for Unity — Editor Plugin Guide
+
+Use this guide to configure and run MCP for Unity inside the Unity Editor. Installation is covered elsewhere; this document focuses on the Editor window, client configuration, and troubleshooting.
+
+## Open the window
+- Unity menu: Window > MCP for Unity
+
+The window has four areas: Server Status, Unity Bridge, MCP Client Configuration, and Script Validation.
+
+---
+
+## Quick start
+1. Open Window > MCP for Unity.
+2. Click “Auto-Setup”.
+3. If prompted:
+   - Select the packaged server folder (`Server`) if you want to run the bundled implementation.
+   - Install Python and/or uv/uvx if missing so the server can be managed locally.
+   - For Claude Code, ensure the `claude` CLI is installed.
+4. Click “Start Bridge” if the Unity Bridge shows “Stopped”.
+5. Use your MCP client (Cursor, VS Code, Windsurf, Claude Code) to connect.
+
+---
+
+## Server Status
+- Status dot and label:
+  - Installed / Installed (Embedded) / Not Installed.
+- Mode and ports:
+  - Mode: Auto or Standard.
+  - Ports: Unity (varies; shown in UI), MCP 6500.
+- Actions:
+  - Auto-Setup: Registers/updates your selected MCP client(s), ensures bridge connectivity. Shows “Connected ✓” after success.
+  - Rebuild MCP Server: Rebuilds the Python based MCP server
+  - Select server folder…: Choose the local `Server` folder (dev only; usually not needed when using uvx).
+  - Verify again: Re-checks server presence.
+  - If Python isn’t detected, use “Open Install Instructions”.
+- HTTP Server Command foldout:
+  - Expands to display the exact `uvx` command Unity will run.
+  - Includes a copy button and the “Start Local HTTP Server” action so you can launch or reuse the command elsewhere.
+
+---
+
+## Unity Bridge
+- Shows Running or Stopped with a status dot.
+- Start/Stop Bridge button toggles the Unity bridge process used by MCP clients to talk to Unity.
+- Tip: After Auto-Setup, the bridge may auto-start in Auto mode.
+
+---
+
+## MCP Client Configuration
+- Select Client: Choose your target MCP client (e.g., Cursor, VS Code, Windsurf, Claude Code).
+- Per-client actions:
+  - Cursor / VS Code / Windsurf:
+    - Auto Configure: Writes/updates your config to launch the server via `uvx` with the current package version:
+      - Command: uvx (or your overridden path)
+      - Args: --from <git-url> mcp-for-unity
+    - Manual Setup: Opens a window with a pre-filled JSON snippet to copy/paste into your client config.
+    - Choose UV Install Location: If uv/uvx isn’t on PATH, select the executable.
+    - A compact “Config:” line shows the resolved config file name once uv/server are detected.
+  - Claude Code:
+    - Register with Claude Code / Unregister MCP for Unity with Claude Code.
+    - If the CLI isn’t found, click “Choose Claude Install Location”.
+    - The window displays the resolved Claude CLI path when detected.
+
+Notes:
+- The UI shows a status dot and a short status text (e.g., “Configured”, “uv Not Found”, “Claude Not Found”).
+- Use “Auto Configure” for one-click setup; use “Manual Setup” when you prefer to review/copy config.
+
+---
+
+## Script Validation
+- Validation Level options:
+  - Basic — Only syntax checks
+  - Standard — Syntax + Unity practices
+  - Comprehensive — All checks + semantic analysis
+  - Strict — Full semantic validation (requires Roslyn)
+- Pick a level based on your project’s needs. A description is shown under the dropdown.
+

+
+## Tips
+- Use Cmd+Shift+M (macOS) / Ctrl+Shift+M (Windows, Linux) to toggle the MCP for Unity window.
+- Enable “Show Debug Logs” in the header for more details in the Console when diagnosing issues.
