Unreal Engine API Documentation MCP Server

Accurate UE5 C++ API docs for AI agents. Prevents hallucinated signatures and includes. Its README documents 5 tools, including search_unreal_api, get_function_signature, get_include_path. It runs locally over stdio via the published package.

People connecting documentation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Unreal Engine API Documentation

before you install - you'll need

Set UNREAL_VERSION, UNREAL_PROJECT_PATH before connecting.

Claude Code

claude mcp add codeturion-unreal-api-mcp -- uvx unreal-api-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "codeturion-unreal-api-mcp": {
      "command": "uvx",
      "args": [
        "unreal-api-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package unreal-api-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.Codeturion is GitHub-verified and matches the repo owner

03 · What Unreal Engine API Documentation can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can resolve include for a type, and check if an API is obsolete.

The 5 tools it gives your agent

get_function_signature: - Exact signature with parameters and return type
get_include_path: - Resolve #include for a type
get_class_reference: - Full class reference card
get_deprecation_warnings: - Check if an API is obsolete
