About unreal-api-mcp
Codeturion/unreal-api-mcp
Instant, accurate Unreal Engine API lookups instead of expensive source file reads, saving your agent tokens, context, and hallucinations.
Implements an MCP server with pre-built SQLite databases for each UE version (5.5+), enabling sub-millisecond exact lookups and sub-5ms full-text searches across 114K+ engine records without requiring local source installation. Covers all runtime, editor, and developer modules plus 158 Blueprint node types and editor graph internals, with automatic weekly updates and patch-version fallback. Integrates with Claude, Cursor, Windsurf, and any MCP-compatible IDE through environment-based version detection from `UNREAL_VERSION` or `.uproject` metadata.
About unreal-mcp
chongdashu/unreal-mcp
Enable AI assistant clients like Cursor, Windsurf and Claude Desktop to control Unreal Engine through natural language using the Model Context Protocol (MCP).
Implements a native C++ TCP server plugin paired with a Python MCP server using FastMCP, enabling comprehensive Unreal workflows including actor manipulation, Blueprint creation with node graph editing, and real-time viewport control. The architecture uses stdio transport between AI clients and the Python server, which communicates via TCP (port 55557) with the Unreal plugin to execute serialized commands and return responses.
