Codeturion/unity-api-mcp
Instant, accurate Unity API lookups instead of expensive source file reads, saving your agent tokens, context, and hallucinations
Implements an MCP server with version-specific SQLite databases (~18–24 MB each) for Unity 2022, 2023, and 6, parsed from official XML documentation and C# source. Provides five tools—search, method signatures, namespace resolution, class references, and deprecation checks—all returning results in <15ms with BM25-ranked search and tuned column weights. Integrates with Claude Code, Cursor, Windsurf, and any MCP client; auto-detects Unity version from `ProjectSettings/ProjectVersion.txt` or explicit environment variables.
