unity-api-mcp

MCP server that gives AI agents accurate Unity API documentation. Prevents hallucinated signatures, wrong namespaces, and deprecated API usage.

Supports Unity 2022 LTS, 2023, and Unity 6 with separate databases for each version. Works with Claude Code, Cursor, Windsurf, or any MCP-compatible AI tool. No Unity installation required.

Quick Start

Add to your MCP config (.mcp.json, mcp.json, or your tool's MCP settings), setting UNITY_VERSION to match your project:

{
  "mcpServers": {
    "unity-api": {
      "command": "uvx",
      "args": ["unity-api-mcp"],
      "env": {
        "UNITY_VERSION": "2022"
      }
    }
  }
}

Valid values: "2022", "2023", or "6".

On first run the server downloads the correct database (~18-24 MB) to ~/.unity-api-mcp/.

How It Works

Version detection. The server figures out which Unity version to serve:

Priority	Source	Example
1	`UNITY_VERSION` env var	`"2022"`, `"6"`, or `"6000.3.8f1"`
2	`UNITY_PROJECT_PATH`	Reads `ProjectSettings/ProjectVersion.txt`, maps `2022.3.62f1` to `"2022"`
3	Default	`"6"`

Database download. If the database for that version isn't cached locally, it downloads from GitHub (one time).
Serve. All tool calls query the version-specific SQLite database. Every query returns in <15ms.

Each version has its own database with the correct signatures, deprecation warnings, and member lists for that release.

Tools

Tool	Purpose	Example
`search_unity_api`	Find APIs by keyword	"Tilemap SetTile", "async load scene"
`get_method_signature`	Exact signatures with all overloads	`UnityEngine.Physics.Raycast`
`get_namespace`	Resolve `using` directives	"SceneManager" -> `using UnityEngine.SceneManagement;`
`get_class_reference`	Full class reference card	"InputAction" -> all methods/fields/properties
`get_deprecation_warnings`	Check if an API is obsolete	"WWW" -> Use UnityWebRequest instead

Coverage

All UnityEngine and UnityEditor modules, plus packages parsed from C# source: Input System, Addressables, uGUI, TextMeshPro, AI Navigation, and Netcode.

Version	Records	Deprecated	Modules	Size
Unity 2022 LTS	32,000	442	86 XML + packages	18 MB
Unity 2023	31,387	436	92 XML	18 MB
Unity 6	42,223	516	139 XML + packages	24 MB

Does not cover third-party assets (DOTween, VContainer, Newtonsoft.Json). For those, rely on project source.

Benchmarks

In a 10-step research workflow, MCP uses 4x fewer tokens than a skilled agent and 11x fewer than a naive agent:

The gap holds across every question type. MCP wins on simple lookups and complex multi-part research alike:
