Handshake ping to verify the plugin listener is responsive.
AI agents call check_plugin_status to retrieve information from PyNet Bridge 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 the plugin listener without modifying, executing, or deleting anything. It is a read-only health check operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool performs a 'handshake ping to verify the plugin listener is responsive' — a diagnostic query with no side effects.
Attacks that exploit this kind of access
Handshake ping to verify the plugin listener is responsive. It is categorised as a Read tool in the PyNet Bridge MCP Server, which means it retrieves data without modifying state.
Register the PyNet Bridge MCP server in PolicyLayer and add a rule for check_plugin_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 PyNet Bridge. Nothing to install.
check_plugin_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_plugin_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_plugin_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_plugin_status is provided by the PyNet Bridge MCP server (rafael-nunezdearenas/pynetbridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
