Run a comprehensive health check verifying D-Tools API connectivity, configuration, webhook handler registration, and rate limiter status.
AI agents call health_check to retrieve information from D-Tools MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The health_check tool performs diagnostic queries to assess system state and connectivity. It retrieves status information without side effects, making it a Read operation. The blast radius of misuse is minimal—a malicious actor could only learn about system health and configuration status, which carries low severity risk.
From the tool's definition Tool description states it 'verifies' and checks status of API connectivity, configuration, webhook handler registration, and rate limiter status.
Attacks that exploit this kind of access
Run a comprehensive health check verifying D-Tools API connectivity, configuration, webhook handler registration, and rate limiter status. It is categorised as a Read tool in the D-Tools MCP Server MCP Server, which means it retrieves data without modifying state.
Register the D-Tools MCP Server MCP server in PolicyLayer and add a rule for health_check: 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 D-Tools MCP Server. Nothing to install.
health_check 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_check 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_check. 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_check is provided by the D-Tools MCP Server MCP server (saml1211/d-tools-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
