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.
Semantic code index that extracts domain concepts, naming conventions, and behavioral similarity from codebases. One tool call instead of 19, 20x fewer tokens for codebase understanding queries.
C++26 paper reference MCP (cpp26-ref) backing a Claude Code plugin: lookuppaper, fuzzy search, compilerstatus over a 216-paper ISO/IEC 14882:2026 corpus. The plugin's skill + reviewer subagent use these tools to bias Claude toward reflection, contracts, std::execution senders, embed, expansion statements — even when the local compiler lags. 95% on a held 39-task eval gate.
