AI agents call health_check to retrieve information from BrowserPilot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves diagnostic and status information from the MCP service, browser extension, native host, and browser access state. It performs only read operations to assess system health and readiness, with no capability to modify, execute, or destroy data. The low severity reflects minimal blast radius if misused: worst case is an agent reading redundant status information.
From the tool's definition Tool name 'health_check' and description indicating it 'returns structured diagnostic information' about status and 'check whether the browser automation bridge is ready' — purely informational queries with no side effects.

Register the BrowserPilot 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 BrowserPilot MCP. 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 BrowserPilot MCP server (sept-7-qi/browserpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
