Advances a device sign-in. Terminal outcomes are DATA, not errors (verifyConn {active:false} discipline) — the status set is closed: pending|connected|denied|expired. pollSlow collapses to "pending" on the wire; the raised cadence rides interval.

Arguments

FieldTypeRequiredDefaultValuesDescription
flowstringyesFlow is the id deviceStartOut returned. Expired or another user's flow is indistinguishable from an unknown one: 404.
providerstringyesProvider is the user-scoped provider's registry id, from the path.

tools/list declares a type and a description for each field and nothing further. The Required column is taken from POST /v1/connectors/{provider}/device/{flow}/poll, the operation this tool dispatches to — the same declaration the REST API validates against. A means neither the door nor that operation constrains the field.

Call it

A tools/call carries every argument in one flat object — nothing binds to a path or a query string. This call carries exactly the arguments the operation requires, so it is the smallest one that can run.

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": "post_v1_connectors_provider_device_flow_poll",
         "arguments": {
           "flow": "<flow>",
           "provider": "<provider>"
         }
       }
     }'

Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. 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.
