Findings
Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: .
Severity: Medium2 findings
Suggested fix: Require MCP authorization for servers that expose state-changing tools.
Severity: MediumStatus: OpenSQ-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 · Last seen
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.
Severity: Low8 findings
Severity: LowStatus: OpenSQ-TOOL-DESTRUCTIVE-NO-ANNOTATION
Destructive tool without annotations
A tool that appears to delete data, change permissions or run code declares no tool annotations.

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.
