Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: Nov 14, 2026, 06:26 UTC.

Severity: Critical2 findings

CriticalOpenSQ-TOOL-CONCEALMENT

Text asks the AI model to hide actions from the user

Model-facing text instructs the AI model to hide actions or information from the user.

First seen Oct 15, 2026 · Last seen Nov 14, 2026

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

CriticalOpenSQ-TOOL-INJECTION-INSTRUCTIONS

Instructions addressed to the AI model

Model-facing text contains instructions addressed to the AI model rather than a description of the tool (for example to override prior instructions, to act before using tools, or to react to trigger phrases).

First seen Oct 15, 2026 · Last seen Nov 14, 2026

Suggested fix: Describe what the tool does and its parameters. Do not include instructions to the model about other tools, the user or the conversation.

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.
