What it does

Unity API MCP provides AI agents with direct access to accurate Unity API documentation. It replaces expensive and error-prone source file reads with high-speed SQLite queries, ensuring the agent uses correct signatures, namespaces, and avoids deprecated APIs for Unity 2022, 2023, and Unity 6.

Tools

search_unity_api: Find APIs by keyword (e.g., "async load scene").
get_method_signature: Get exact signatures with all overloads for a specific method.
get_namespace: Resolve the correct using directive for a given type.
get_class_reference: Retrieve a full reference card for a Unity class including all members.
get_deprecation_warnings: Check if a specific API is obsolete and find the recommended replacement.

Installation

Use uvx to run the server. Add the following to your MCP config:

{
  "mcpServers": {
    "unity-api": {
      "command": "uvx",
      "args": ["unity-api-mcp"],
      "env": { "UNITY_VERSION": "6" }
    }
  }
}
