Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Drive the Unreal Engine 5.7 editor from any MCP client over a local TCP socket — 105 editor-automation tools (72 native C++ + 33 bridge-side). Native C++ plugin + thin Python bridge, 50ms round-trips. 498 tests, MIT.
Deterministic D&D 5e (SRD 5.2.1) rules verdicts for agents: cited legality checks for whole turns, legal-action enumeration, advantage math, and hash-stamped game-state lineage. Refuses what the rules don't decide (exit 2), quotes the rule text on every verdict, zero dependencies.
