MCP server that gives AI agents accurate Unreal Engine C++ API documentation. Saves tokens, context, and time. Prevents hallucinated signatures, wrong `#include` paths, and deprecated API usage.
Works with Claude Code, Cursor, Windsurf, or any MCP-compatible AI tool. No Unreal Engine installation required. Check the supported versions. New versions are detected and built automatically every week.
Quick Start
Add to your MCP config (.mcp.json, mcp.json, or your tool's MCP settings), setting UNREAL_VERSION to match your project:
{
"mcpServers": {
"unreal-api": {
"command": "uvx",
"args": ["unreal-api-mcp"],
"env": {
"UNREAL_VERSION": "5.5"
}
}
}
}Set this to match your project's UE version. See [supported versions](https://github.com/Codet

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control.

Questions
What is the Unreal API MCP server?
Instant, accurate Unreal Engine API lookups instead of expensive source file reads, saving your agent tokens, context, and hallucinations.
What tools does Unreal API expose?
5 in total: 5 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Unreal API safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Unreal API need?
No credential environment variables were found in its source, so it appears to need none.
How does Unreal API run?
It speaks stdio, so it runs as a local process your client starts. It is published on PyPI as unreal-api-mcp.
How current is this page?
The grade is for one exact copy of the source (925c3c1f6fbb), read on 2026-10-07. The repository is watched and re-audited when it changes.
