Best security MCP servers

Security servers scan code and dependencies, look up threat intelligence, and query SIEM tools. Hold them to a higher bar: published source, pinned versions, and a clear tool list. 1524 published MCP servers match this ranking. The highest trust scores right now are Flood at 67, Gbif at 67, Genderize at 67. 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 security MCP servers is not a paid placement.
