Check the live HTTP status of any URL, optionally verify against an expected code. Useful for uptime monitoring, redirect validation, and link checking
AI agents call http_status_checker to retrieve information from APIMesh MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs HTTP HEAD/GET requests to retrieve status codes and headers from remote URLs. It queries external systems but does not create, modify, delete, or execute arbitrary code. The only side effect is a network request to fetch metadata, which is non-destructive and read-only.
From the tool's definition Tool description states 'Check the live HTTP status of any URL' and lists use cases as 'uptime monitoring, redirect validation, and link checking' — all read-only operations that retrieve status information without modifying data.
Attacks that exploit this kind of access
Check the live HTTP status of any URL, optionally verify against an expected code. Useful for uptime monitoring, redirect validation, and link checking. It is categorised as a Read tool in the APIMesh MCP Server MCP Server, which means it retrieves data without modifying state.
Register the APIMesh MCP Server MCP server in PolicyLayer and add a rule for http_status_checker: 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 APIMesh MCP Server. Nothing to install.
http_status_checker 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 http_status_checker 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 http_status_checker. 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.
http_status_checker is provided by the APIMesh MCP Server MCP server (mbeato/apimesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
