Unity API MCP
Supports UIby codeturion
Instant, accurate Unity API documentation for AI agents to prevent hallucinations and reduce token waste.
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 correctusingdirective 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a full reference card for a Unity class including all members.get_deprecation_warnings: Check if a specific API is obsolete and find the recommended replacement.
