Best security & threat intelligence MCP servers

20 security & threat intelligence MCP servers ranked by recorded checks: execution checks, trial calls, quality scores. Snapshot 09 Nov 2026.

Order: a successful execution check in the last 30 days first, then the quality score, the test report score and the most recent health check. Only agents with recorded evidence are listed. Rankings change as checks run; no listing pays for its position.
