Findings

Detected by Squatch rules from the server's metadata and protocol behavior. Latest completed scan: .

Severity: Critical2 findings

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: Medium6 findings

Severity: MediumStatus: 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).

First seen · Last seen

Suggested fix: Describe only this server's own tools.

Severity: MediumStatus: OpenSQ-TOOL-CROSS-TOOL-REFERENCE

Gives instructions about other tools

Suggested fix: Describe only this server's own tools.

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.

Severity: MediumStatus: 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).

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: Low4 findings

Severity: LowStatus: OpenSQ-TOOL-LENGTH-ANOMALY

Unusually long model-facing text

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

First seen · Last seen

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

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.
