Findings
Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: .
Severity: Medium1 finding
Suggested fix: Require MCP authorization for servers that expose state-changing tools.
Severity: Low4 findings
Severity: LowStatus: OpenSQ-REPO-MISSING
No source repository linked
No source repository is linked in the registry entry.

Severity: LowStatus: 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.

Suggested fix: Set readOnlyHint to false and destructiveHint to reflect the tool's behavior.
Severity: LowStatus: OpenSQ-CONFORMANCE-MODERN-FAILURE
Protocol conformance checks failed
The server failed one or more MCP protocol conformance checks.

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.
