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.
