Unity API Documentation

codeturion/unity-api-mcp

Gives Claude direct access to Unity's API documentation for 2022 LTS, 2023, and Unity 6 through a local SQLite database. You can search by keyword, pull exact method signatures with all overloads, resolve namespaces, check deprecation status, or get full class references. It covers all UnityEngine and UnityEditor modules plus common packages like Input System and Addressables. The server downloads version-specific databases on first run and queries return in under 15ms. Useful when you're tired of Claude hallucinating method signatures or suggesting deprecated APIs. Set UNITY_VERSION in your config or point it at a project path to auto-detect from ProjectVersion.txt.
