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. 1983 published MCP servers match this ranking. The highest trust scores right now are webcomponents-react-mcp-server at 55, Numerador de facturas at 55, NeuroDynamic Audio and LLM APIs at 55. 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.
