Get the current MQTT connection status.
AI agents call mqtt_status to retrieve information from MQTT MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool merely queries and returns the current connection status of an MQTT broker. It performs no operations that create, modify, delete, or execute external processes. Status checks are informational reads with no blast radius if misused by an AI agent.
From the tool's definition Tool name 'mqtt_status' and description 'Get the current MQTT connection status' indicate a query operation that retrieves status information without modifying state or triggering side effects.
Attacks that exploit this kind of access
Get the current MQTT connection status. It is categorised as a Read tool in the MQTT MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MQTT MCP Server MCP server in PolicyLayer and add a rule for mqtt_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 MQTT MCP Server. Nothing to install.
mqtt_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 mqtt_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 mqtt_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.
mqtt_status is provided by the MQTT MCP Server MCP server (sergiudanstan/mqtt-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
