AI agents call health to retrieve information from Addressr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a diagnostic/monitoring tool that retrieves service status without side effects. It merely queries and returns static information about the API's operational state, fitting the 'Read' category. Severity is low because misuse (e.g., frequent polling) causes no damage—only potential minor resource consumption.
From the tool's definition Tool returns read-only status information: 'version, timestamp, and health status'. No modifications, deletions, or external operations triggered.
Attacks that exploit this kind of access
Check API service status. Returns version, timestamp, and health status. It is categorised as a Read tool in the Addressr MCP Server, which means it retrieves data without modifying state.
Register the Addressr MCP server in PolicyLayer and add a rule for health: 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 Addressr. Nothing to install.
health 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 health 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 health. 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.
health is provided by the Addressr MCP server (mountain-pass/addressr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
