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.
About UnityMCP
isuzu-shiranui/UnityMCP
Unity Editor integration with Model Context Protocol (MCP) enabling AI assistants like Claude to interact with Unity projects. Features a TypeScript MCP server and C# Unity plugin with extensible command handler architecture, TCP/IP communication, and dynamic plugin discovery.
Supports all three MCP handler types (commands, resources, and prompts) with automatic discovery on both C# and TypeScript sides, enabling bidirectional AI-Unity workflows. The framework uses a scalable plugin architecture where custom handlers implement well-defined interfaces and are automatically registered via reflection, with communication serialized as JSON over TCP/IP between the Unity Editor and Claude Desktop. Includes built-in installer tooling for integrating the TypeScript MCP server with Claude Desktop configuration, plus sample handlers demonstrating code execution capabilities.
