mcp-unity and unity-api-mcp
These are complements: the first provides IDE integration to connect Claude with a live Unity Editor instance, while the second provides an MCP server for efficient API documentation lookups, and both can be used together to give an AI coding agent both real-time project access and accurate API reference without hallucinations.
About mcp-unity
CoderGamester/mcp-unity
Model Context Protocol (MCP) plugin to connect with Unity Editor — designed for Cursor, Claude Code, Codex, Windsurf and other IDEs
Provides AI agents with 25+ tools for scene manipulation, asset management, and testing—including GameObject modification, prefab creation, scene loading, and script recompilation—via a Node.js MCP server that communicates with Unity Editor through stdio transport. Automatically surfaces Unity's PackedCache to IDE workspaces for improved code intelligence on engine dependencies, bridging the gap between AI coding assistants and real-time game development workflows.
About unity-api-mcp
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.
