Checks the status and connectivity of the HTTP listener service used for tool delegation.
AI agents call check_listener_status to retrieve information from Beep Boop MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves status information about an HTTP listener service. It is a diagnostic read-only operation that queries the state of a service component without side effects, modifications, or execution of user-provided logic. The blast radius of misuse is minimal—an agent could only obtain status information, which is typically non-sensitive in most contexts.
From the tool's definition Tool name is 'check_listener_status' and description states it 'Checks the status and connectivity' — these are query/monitoring operations with no data modification or execution of external commands.
Attacks that exploit this kind of access
Checks the status and connectivity of the HTTP listener service used for tool delegation. It is categorised as a Read tool in the Beep Boop MCP MCP Server, which means it retrieves data without modifying state.
Register the Beep Boop MCP server in PolicyLayer and add a rule for check_listener_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 Beep Boop MCP. Nothing to install.
check_listener_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 check_listener_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 check_listener_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.
check_listener_status is provided by the Beep Boop MCP server (thesammykins/beep_boop_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
