AI agents call usg_connection_status to retrieve information from AF_MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and displays the connection configuration status of a USG6000F security device. The description explicitly notes that it does not display plaintext passwords, indicating it is a safe read operation with appropriate security controls. No side effects, modifications, or irreversible actions are performed. It fits the 'Read' category as a retrieval/query operation with minimal risk.

Register the AF_ MCP server in PolicyLayer and add a rule for usg_connection_status: 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 AF_MCP. Nothing to install.
usg_connection_status 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 usg_connection_status 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 usg_connection_status. 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.
usg_connection_status is provided by the AF_ MCP server (xiaqijun/af_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
