Is co.promptguard/security safe to use?

co.promptguard/security has not been scored against the OWASP MCP Top 10 yet, so this page shows no grade. Most MCP servers are credential-gated — a scan has to actually connect, and we will not guess a number we did not measure. Unknown is not unsafe. Point the open-source scanner at it yourself with `npx mcpr scan`.

How grades are assigned, the ten checks behind it, and the point maths are all on how we score MCP server trust.

What is the co.promptguard/security trust score based on?

Ten checks derived from the OWASP MCP Top 10, run against the live server by the open-source MCP Vouch scanner. Applicable checks are summed and scaled to 0–100; checks that do not apply to the server's transport are skipped and leave the denominator entirely.

How do I install co.promptguard/security?

co.promptguard/security is installed like any other MCP server — add it to your client's MCP configuration. Cross-client one-click install is coming to MCP Registry; until then, the repository and homepage links on this page carry the maintainer's own instructions.
