| Tool | post_v1_marketing_sequences_id_enrollments_eid_cancel |
| Door | https://api.hanzo.ai/v1/mcp |
| Method | tools/call (JSON-RPC 2.0) |
| Arguments | 2, 2 required |
| Operation | POST /v1/marketing/sequences/{id}/enrollments/{eid}/cancel |
| Product | marketing |
Arguments
| Field | Type | Required | Default | Values | Description |
|---|---|---|---|---|---|
eid | string | yes | — | — | EID is the enrollment id from the path, as returned by a single-address enroll. |
id | string | yes | — | — | ID is the sequence 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/marketing/sequences/{id}/enrollments/{eid}/cancel, 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 '{

"arguments": {

}
}'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.
