status_summary — The rollup a status page shows: how many services are up, which are down, the slowest one and the overall state.
check_services — Up/down sweep of up to 10 services in one call, with status code and response time for each.
service_status — Detail for one service: HTTP status, response time, server, redirect chain and the first text on the page.
port_check — Check whether TCP ports on a host accept connections, with the service usually found on each port.
dns_propagation — Ask Cloudflare, Google and AdGuard for the same record and report whether they agree, plus the lowest TTL.
ssl_chain — The whole certificate chain from the live handshake: leaf, intermediates, expiry and whether the chain is trusted.

Setup

No setup. Every check runs live from the server itself, so there is no key or account.

Premium tools

These tools need a license key:

header_audit
cert_forecast

Buy a key at https://mcp-marketplace.io/server/io-github-mrfentmen-statping-mcp and set it in your MCP client config:

"env": { "MCP_LICENSE_KEY": "mcp_live_..." }

The key is checked against MCP Marketplace, cached for 24 hours, and keeps working offline once one check has succeeded. Every other tool on this server stays free.
