Findings
Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: .
Severity: High2 findings
Suggested fix: Require MCP authorization for servers that expose state-changing tools.
Severity: HighStatus: OpenSQ-TOOL-SENSITIVE-PATH-REFERENCE
References credential or key locations
Model-facing text references credential, key or configuration file locations unrelated to the tool's stated purpose.
First seen · Last seen
Suggested fix: Remove references to credential files, key stores and client configuration files.
Severity: Medium3 findings
Severity: MediumStatus: OpenSQ-TOOL-ANNOTATION-UNDERCLAIM
Annotations understate what the tool does
The tool declares itself read-only, but its name or description indicates it changes, deletes or runs something. Clients that auto-approve read-only tools would run it without confirmation.
First seen · Last seen
Suggested fix: Set readOnlyHint to false and destructiveHint to reflect the tool's behavior.

Severity: MediumStatus: OpenSQ-TOOL-PRIVILEGE-PARAM
Parameter requests elevated privileges
A tool parameter requests elevated privileges, impersonation or bypassing of checks.

Suggested fix: Remove privilege-escalation switches from model-controlled arguments.
Severity: Low2 findings
Severity: LowStatus: OpenSQ-REPO-MISSING
No source repository linked
No source repository is linked in the registry entry.

Suggested fix: Add a repository to server.json.
Severity: LowStatus: OpenSQ-CONFORMANCE-MODERN-FAILURE
Protocol conformance checks failed
The server failed one or more MCP protocol conformance checks.
First seen · Last seen
Suggested fix: Review the failed checks against the MCP specification.
Severity: Info3 findings
Severity: InfoStatus: OpenSQ-TOOL-EXFIL-SHAPED-PARAM
Free-text parameter commonly used to collect conversation data
A free-text parameter has a name commonly abused to collect conversation, prompt or environment data.
First seen · Last seen
Suggested fix: Constrain the parameter (enum, maxLength) or rename it to reflect its purpose; never ask the model to fill it with conversation content.

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.
