"A tool to evaluate the suitability of semantic search queries" matching MCP connectors:

Query 90 days of honeypot probe data: IP reputation, scanners, CVE probing, TLS/SSH fingerprints.

Scans MCP servers for tool poisoning, prompt injection and supply chain risks.

A skeptical senior-engineer code reviewer over MCP: risk-scans unified diffs, flags AI-generated-code tells, reports complexity hotspots, scans for leaked secrets, and runs an OWASP security pass — real analyzers, no external APIs. Free tier, no signup.

Free lockfile malware check plus paid pre-install scan of any skill, tool, or package.

Check if an MCP server tool changed or hides injection patterns before you trust it.

Scan a website for vulnerabilities: OWASP Top 10, CVEs, SSL, headers - with plain-English fixes

Detect malicious or vulnerable npm packages: registry search, OSV.dev and GitHub advisory lookups

Scan any website or MCP server for agent-trust-readiness; returns a signed, verifiable scorecard.
