Findings

Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: Nov 6, 2026, 19:00 UTC.

HighOpenSQ-SERVER-INSTRUCTIONS-INJECTION

The server's instructions field contains directives addressed to the AI model beyond describing how to use the server.

First seen Nov 6, 2026 · Last seen Nov 6, 2026

Suggested fix: Limit server instructions to usage guidance for this server's own tools.

MediumOpenSQ-SERVER-TOOLS-NONDETERMINISTIC

Two identical tools/list requests in the same scan returned different tool definitions.

First seen Nov 6, 2026 · Last seen Nov 6, 2026

Suggested fix: Return a deterministic tool list for identical requests.

LowOpenSQ-CONFORMANCE-MODERN-FAILURE

The server failed one or more MCP protocol conformance checks.

First seen Nov 6, 2026 · Last seen Nov 6, 2026

Suggested fix: Review the failed checks against the MCP specification.

LowOpenSQ-REPO-MISSING

No source repository is linked in the registry entry.

First seen Nov 6, 2026 · Last seen Nov 6, 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.
