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.
AI-powered paper annotation MCP server. Reads papers, highlights key findings with semantic color coding, explains formulas, and writes structured reading notes — all saved back to Zotero. Features two-phase workflow for large PDFs (63–80% context savings) and batch annotations.
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.
