Suggested fix: Remove any wording that asks the model to act silently or withhold information from the user.

Severity: HighStatus: OpenSQ-TOOL-SENSITIVE-PATH-REFERENCE

References credential or key locations

Severity: HighStatus: OpenSQ-SERVER-INSTRUCTIONS-INJECTION

Server instructions contain directives to the AI model

The server's instructions field contains directives addressed to the AI model beyond describing how to use the server.

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.
