Best knowledge MCP servers

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. 1982 published MCP servers match this ranking. The highest trust scores right now are Matrix at 55, Sezzlee PDF at 55, picomcp docs 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.
