listMachines

Returns every machine the caller's org has — Visor's registry, the live DigitalOcean droplets and the DOKS worker nodes (deduped into one union), plus the BYO machines that dialed in via hanzo link (provider "byo").

A source Visor cannot answer for is logged and skipped, never an error: one wedged upstream must not hide the machines the other sources can see.

Arguments

This tool declares no arguments. Call it with an empty arguments object.

Call it

A tools/call carries its arguments in one flat object. This tool declares none, so the object is empty.

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "listMachines",
         "arguments": {}
       }
     }'

tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing. How to get a key →

The operation behind it

The same capability over plain HTTP is in the machines API reference, on https://api.hanzo.ai.
