MCP tool reference

The tools below are callable from any MCP-compatible client (Claude, Cursor, etc.). Parameter names match the MCP server's tool schema exactly — a wrong key (e.g. passing domain instead of host to ssl) is rejected.

MCP tools take no node list — the server picks one node, runs the probe, and returns that node's result. For multi-node comparison use the REST probe API or the online tools.
