Severity: CriticalStatus: OpenSQ-TOOL-CROSS-TOOL-REFERENCE
Gives instructions about other tools
Model-facing text gives the AI model instructions about tools that this server does not provide (tool shadowing).

Findings
Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: .
Severity: Critical6 findings
Suggested fix: Describe only this server's own tools.
Severity: CriticalStatus: OpenSQ-TOOL-SHELL-PAYLOAD
Shell command patterns in model-facing text
Model-facing text contains shell command patterns such as piping downloads into a shell or recursive deletion.
First seen · Last seen
Suggested fix: Remove shell commands from descriptions.
Severity: CriticalStatus: OpenSQ-TOOL-EXFIL-DIRECTIVE
Asks the AI model to pass conversation data or secrets
Model-facing text instructs the AI model to place conversation content, prompts, tool history or secrets into tool arguments or external destinations.
First seen · Last seen
Suggested fix: Do not ask the model to include conversation, prompt or credential content in arguments.
Severity: CriticalStatus: OpenSQ-TOOL-INJECTION-INSTRUCTIONS
Instructions addressed to the AI model
Model-facing text contains instructions addressed to the AI model rather than a description of the tool (for example to override prior instructions, to act before using tools, or to react to trigger phrases).
First seen · Last seen
Suggested fix: Describe what the tool does and its parameters. Do not include instructions to the model about other tools, the user or the conversation.
Severity: CriticalStatus: OpenSQ-TOOL-PREFERENCE-MANIPULATION
Pressures the AI model to prefer this tool
Model-facing text pressures the AI model to always choose this tool or avoid others.
First seen · Last seen
Suggested fix: Describe the tool's function neutrally.
Severity: CriticalStatus: OpenSQ-TOOL-SENSITIVE-PATH-REFERENCE
References credential or key locations
Model-facing text references credential, key or configuration file locations unrelated to the tool's stated purpose.
First seen · Last seen
Suggested fix: Remove references to credential files, key stores and client configuration files.
Severity: High4 findings
Severity: HighStatus: OpenSQ-SERVER-AUTH-NONE-WRITE
State-changing tools available without authentication
The remote server lists state-changing tools without requiring authentication.
First seen · Last seen
Suggested fix: Require MCP authorization for servers that expose state-changing tools.
Severity: HighStatus: OpenSQ-SERVER-INSTRUCTIONS-INJECTION
Server instructions contain directives to the AI model
The server's instructions field contains directives addressed to the AI model beyond describing how to use the server.
First seen · Last seen
Suggested fix: Limit server instructions to usage guidance for this server's own tools.
Severity: HighStatus: OpenSQ-TOOL-EXFIL-DIRECTIVE

Severity: Medium5 findings
Severity: MediumStatus: OpenSQ-TOOL-CREDENTIAL-ARGUMENT
Asks the AI model to supply credentials as arguments
A tool parameter asks the AI model to supply a password, token, key or similar credential, which the model can see and repeat.
First seen · Last seen
Suggested fix: Obtain credentials through server-side configuration or MCP authorization instead of tool arguments.

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.
