Check auth freshness and endpoint connectivity. Reports token persistence state:
AI agents call health_status to retrieve information from PropProfessor MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports system health and authentication metadata without modifying, executing, or deleting anything. It is a read-only diagnostic utility suitable for monitoring and troubleshooting. The low severity reflects that misuse by an AI agent would only result in information disclosure about the system state, not harm to data or operations.
From the tool's definition Tool description states it 'Check[s] auth freshness and endpoint connectivity' and 'Reports token persistence state' — purely observational/diagnostic operations with no side effects.
Attacks that exploit this kind of access
Check auth freshness and endpoint connectivity. Reports token persistence state:. It is categorised as a Read tool in the PropProfessor MCP MCP Server, which means it retrieves data without modifying state.
Register the PropProfessor MCP server in PolicyLayer and add a rule for health_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 PropProfessor MCP. Nothing to install.
health_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 health_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 health_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.
health_status is provided by the PropProfessor MCP server (j17drake/propprofessor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
