MCP Security Index

Before you install an MCP server, see what it can do. AxioRank enumerates the tools each server declares (read-only, it never calls one) and grades the blast radius of what it can do: write, delete, execute, credential, and wildcard-scope capabilities. Scan a server not listed here.

How the grades work

A grade measures blast radius: how much a server could do if it were compromised or misinstructed, based on the capabilities it declares (write, delete, execute, credential access, wildcard scope). It is not a vulnerability assessment and not a judgment of the vendor. Lower is better: A is 0 to 19, up to F at 80 and above. The scan is read-only. It lists tools and never calls one.

Run a server? You can scan it yourself and embed your grade. See something off? Every server page links a re-scan.
