AI agents call diagnostic to retrieve information from Sl Test without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and reports diagnostic/environmental information without modifying any state. It queries configuration and dependency status, making it a Read operation. Low severity as it only exposes system metadata, though there is a minor concern that environment details could reveal sensitive configuration information.
From the tool's definition 'Provides comprehensive information about the MCP server environment, available dependencies, and configuration status'
Attacks that exploit this kind of access
Provides comprehensive information about the MCP server environment, available dependencies, and configuration status. It is categorised as a Read tool in the Sl Test MCP Server, which means it retrieves data without modifying state.
Register the Sl Test MCP server in PolicyLayer and add a rule for diagnostic: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Sl Test. Nothing to install.
diagnostic is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the diagnostic rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for diagnostic. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
diagnostic is provided by the Sl Test MCP server (sampsonky/xcodebuildmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
