Suggested fix: Limit server instructions to usage guidance for this server's own tools.

Severity: Medium1 finding

Severity: MediumStatus: OpenSQ-TOOL-CROSS-TOOL-REFERENCE

What this scan does not cover

  • Squatch never calls a server's tools, so it cannot see what they actually do at run time.
  • It scans without credentials: tools behind authentication may not be visible.
  • It does not review source code, dependencies or the publisher's infrastructure.
  • A server can change behavior between scans; monitoring compares each scan with the last.
  • Classifications come from tool names, descriptions and schemas, which the publisher controls.
