How we verify
- Sources: every item is checked against a public source we cite (Epic’s forums and docs, the maker’s own site, or GitHub). We never scrape marketplaces.
- What we show: only verified facts. Prices, ratings and engine versions appear only when we could confirm them. Summaries are written by us.
- Order: currently free items first, then items that are useful to the most projects (built-in and always-free tools rank high), then the rest.
- Updates: the “Updated” date changes only when this list’s content changes.
- Editorial independence: this list is not for sale. Sponsors cannot buy, influence or remove a placement here, and no sponsored items appear on best-of pages. Sponsorships appear only in clearly labeled spots elsewhere on the site.
FAQ
What is an Unreal MCP server?
A bridge that exposes editor actions through the Model Context Protocol, so AI clients like Cursor or Claude can call them.
Is it safe to let AI edit my project?
Use version control and back up first. Prefer tools with undoable, journaled edits.
Which one is free?
Monolith is MIT-licensed on GitHub. Check the others’ sites for pricing; we do not show unverified prices.
Why are there fewer than 8 picks?
We only list tools we could verify from their own public pages. We will add more as we verify them.
