Rider AI Assistant¶

Prerequisite: complete the Unity package installation.

Configure¶

Rider uses its Settings UI rather than a generated project file. The current JetBrains AI Assistant expects an mcpServers JSON object:

1. Open MCP > Setup Wizard in Unity.
2. Select Rider AI Assistant to confirm the prerequisite.
3. In Rider, open Settings > Tools > AI Assistant > Model Context Protocol (MCP).
4. Select +, choose the STDIO JSON configuration, and paste:

{
  "mcpServers": {
    "unity-biome-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/german-krasnikov/unity-biome-mcp.git#subdirectory=server",
        "unity-biome-mcp"
      ]
    }
  }
}

1. Select OK, then Apply. Rider starts the server and shows its status.

Keep the Unity project open while using the server. The configuration is owned by Rider; Unity Biome MCP does not generate a Rider JSON or TOML file.

See the JetBrains MCP configuration guide for Rider-specific controls and logs.
