Manifest recorded 2026-10-26 from tools/list answered by the npm package ferrycat@0.3.3 (published to npm as ferrycat, listed in the official MCP registry as io.github.GuoBug/ferrycat 0.3.3), run in an isolated container with no network access and no credentials. The date changes only when the manifest does. Not verified by a maintainer.
Issues
These describe what this server's manifest declares. A product can provide controls that MCP has no
way to express — token revocation, an admin console, audit logs — and this page cannot see them. The absence of a
declaration is not evidence that a control is absent.
critical · irreversible-uncapped · 1 of 8 tools
1 tool is classified as irreversible and declares no limit.
critical · no-revocation · All 8 tools
8 of 8 tools declare no way for the customer to switch them off once granted. This applies to every tool because MCP has no field in which to declare a revocation mechanism; the product may provide one outside MCP that a manifest cannot show.
high · no-expiry · All 8 tools
8 of 8 tools declare no expiry. This applies to every tool because MCP has no field in which to declare an expiry; the product may provide one outside MCP that a manifest cannot show.
high · no-audit-trail · All 8 tools
8 of 8 tools declare no record of their actions that the customer can read. This applies to every tool because MCP has no field in which to declare an audit requirement; the product may provide one outside MCP that a manifest cannot show.
high · uncapped-write · 4 of 8 tools
4 tools can modify data and declare no limit.
low · uncapped-read · 3 of 8 tools
3 tools can read data and declare no limit.
