Questions

How do you decide which servers are security servers?
By the categories each server's own repository declares, mapped onto this job by a hand-kept table. A server can belong to more than one job, and one whose repository declares no matching category is not listed here.
Which security MCP servers rank highest on trust?
Agentic Radar (splx-ai/agentic-radar), Kali Connector (wh0am123/mcp-kali-server) and Security Hub (fuzzinglabs/mcp-security-hub), by trust score and then stars. Ranking never uses popularity to change a verdict.
How many security servers only read?
35 of the 119 declare tools that all only read; 26 expose at least one destructive tool.
