Knowledge servers search wikis, notes, and documentation so answers cite your own pages. The integration token decides what the agent can read, so share only the spaces it needs. 1960 published MCP servers match this ranking. The highest trust scores right now are Carbone MCP at 71, Astria at 71, pdfnative MCP — PDF/A & PDF/X-4 generation, PAdES signing & introspection at 71. The order is the published trust score: registry record, license, maintenance, popularity, documentation, and security signals. Featured slots, when an editor sets them, are labeled and do not change the score. Best knowledge MCP servers is not a paid placement.
