Connect Claude Code to Unity

nanora-unity-mcp writes the Claude Code configuration for you.

1. Open the project in Unity and wait until Window > Unity MCP Server shows Running.
2. Start claude in the project folder. The server has already written .mcp.json there.
3. Run /mcp. nanora-unity-mcp should be listed as connected.

.mcp.json (written by the server)

{
  "mcpServers": {
    "nanora-unity-mcp": { "type": "sse", "url": "http://localhost:<PORT>/sse" }
  }
}

.mcp.json holds an address for this machine, so keep it out of Git (Add to .gitignore in the Setup Wizard).

Skills

When the Claude Code connection is configured, the bundled skills are copied to <Project>/.claude/skills/ — for example /unity-verify-applied, which makes the AI check saved files, the running state and the visible result before it says “done”. See Bundled skills.

If it does not appear

• Start Unity first, then restart claude in the folder that contains .mcp.json.
• curl http://127.0.0.1:<PORT>/health should answer with your projectPath.
