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. 1522 published MCP servers match this ranking. The highest trust scores right now are npm Registry MCP Server at 71, osv-advisory-mcp-server at 71, Imf Portwatch at 70. 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.
