post_v1_auto_runs
Start begins one asynchronous run of a flow: the product dispatches the graph to its durable execution engine (the hanzo tasks plane) and answers immediately with the run record in status running.
Start begins one asynchronous run of a flow: the product dispatches the graph to its durable execution engine (the hanzo tasks plane) and answers immediately with the run record in status running. Poll the run until it reaches completed — its output then holds each node's result keyed by node id — or failed, with the error. A flow whose engine is unreachable answers the product's 503: dispatch is real or it is refused, never queued into the void.

Arguments
| Field | Type | Required | Default | Values | Description |
|---|---|---|---|---|---|
flow | string | — | — | — | Flow is the id of the flow to run. |
input | any | — | — | — | Input is the trigger payload handed to the run, verbatim JSON object. The run's state starts as {"trigger": input}. |
tools/list declares a type and a description for each field and nothing further. 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. Nothing above is required, so every declared argument is shown rather than a guess at which matter.
curl -X POST https://api.hanzo.ai/v1/mcp \
-H "Authorization: Bearer $HANZO_API_KEY" \
-H "Content-Type: application/json" \

}'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.
