unreal-tools-mcp

unreal-tools-mcp is a cursor rule for Cursor from Stramp/Lost-Mines-Phandelver. It costs 9 tokens per session (1,307 once invoked), scanned A, original, MIT.

A collection of tools and Model Context Protocol (MCP) connections for Unreal Engine 5.7 development. They include controls for the Unreal Editor, project files, documentation, and Git.

In plain words
What is it for?
Creating 3D environments such as cities, mansions, and mazes; searching Unreal Engine references and code examples; managing project files; and handling Git commits, branches, merges, history, and diffs.
Why use it?
It reduces the need to switch between the game engine, documentation, file browser, and version-control commands. Natural-language control can help with some world-building tasks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

unreal-tools-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
