MediumOpenSQ-SERVER-AUTH-NONE-WRITE

The remote server lists state-changing tools without requiring authentication.

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

Suggested fix: Require MCP authorization for servers that expose state-changing tools.

LowOpenSQ-REPO-MISSING

No source repository is linked in the registry entry.

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

Suggested fix: Add a repository to server.json.

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.
