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.
Compressed Knowledge Graphs (pre-structured dependency DAGs) as MCP context — agents traverse declared edges instead of inferring from text. Open CKG Benchmark (64 domains, 10,838 queries): 3.8× RAG's F1 at 11× fewer tokens, 42× RDS, 0 fabricated edges by construction. 97 domains, 4 tools, no DB/embeddings. pip install ckg-mcp
Organizational knowledge base for AI agents. Vault-scoped Markdown docs, structured PostgreSQL tables, and files unified by a URI graph. Hybrid semantic + BM25 search, Git-backed version history, multi-tenant ACL with public-share links. Works with Claude Code, Cursor, Windsurf via npx akb-mcp.
