Findings

Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: Nov 9, 2026, 23:20 UTC.

MediumOpenSQ-SERVER-AUTH-NONE-WRITE

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

First seen Oct 18, 2026 · Last seen Nov 9, 2026

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

LowOpenSQ-TOOL-LENGTH-ANOMALY

Model-facing text is unusually long, which consumes context and leaves room to hide content.

First seen Oct 25, 2026 · Last seen Nov 9, 2026

Suggested fix: Shorten descriptions; move long documentation out of model-facing fields.

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.
