Quick liveness check — is the proxy tunnel actually working?
AI agents call borrowip_health_check to retrieve information from BorrowIP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only diagnostic operation. It retrieves the current operational status of the proxy tunnel without modifying, executing external code, or destructively altering any state. Even in the context of a web scraping proxy service, a health check is purely informational and poses minimal risk if invoked by an AI agent. Low severity because the outcome is a boolean status report with no blast radius.
From the tool's definition Tool performs a 'Quick liveness check' to verify tunnel status. It queries state and returns results with no side effects—similar to a ping or health endpoint.
Attacks that exploit this kind of access
Quick liveness check — is the proxy tunnel actually working?. It is categorised as a Read tool in the BorrowIP MCP Server MCP Server, which means it retrieves data without modifying state.
Register the BorrowIP MCP Server MCP server in PolicyLayer and add a rule for borrowip_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 BorrowIP MCP Server. Nothing to install.
borrowip_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 borrowip_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 borrowip_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.
borrowip_health_check is provided by the BorrowIP MCP Server MCP server (wahyuzero/borrowip). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
