Changes

• Default Unreal Engine version is now 5.8 (auto-detection unchanged: UNREAL_VERSION env var > .uproject EngineAssociation > default)
• License changed from PolyForm Noncommercial 1.0.0 to MIT
• UE 5.8 / 5.8.0 databases available (auto-built by the weekly detect workflow)

What's New

• Full UE 5.x coverage: Databases for every version from 5.0 to 5.7, including all patch releases (35 databases total)
• Patch version support: Users on e.g. UE 5.7.3 get an exact patch database, with fallback to 5.7 if unavailable
• Auto-update check: Server checks for database updates on startup (via HEAD request, silent on failure)
• CI automation: Weekly detection of new UE releases with automatic database builds
• Rebuild All workflow: One-click rebuild of all databases (for parser improvements)

Supported Versions

First public release of unreal-api-mcp.

5 MCP tools for accurate Unreal Engine C++ API documentation:

• get_function_signature — exact signatures with parameters and return types
• get_include_path — resolve #include for any type
• get_class_reference — full class member listing
• get_deprecation_warnings — check if an API is obsolete

Coverage: UE 5.5 (99k records), UE 5.6 (109k records), UE 5.7 (114k records). All Engine Runtime, Editor, Developer modules, plus built-in plugins.

Databases download automatically on first run (~43-50 MB).

Supported Versions

39 databases covering every UE 5.x release. Updated automatically via CI.
