Address	`https://api.hanzo.ai/v1/marketing/calendar`
Method	`POST`
Operation	`post_marketing_calendar`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Adds a post to the content calendar. Channel and body are required. A scheduledAt in the future makes the post "scheduled" and the durable sweep publishes it when it comes due — claimed once, so a post publishes at most once; without one it stays a draft.

Request

10 fields, body application/json (required).

Field	In	Type	Required	Description
`body`	body	string	—	Body is the post text.
`channel`	body	string	—	Channel is the target network: x, facebook, instagram, linkedin, tiktok, youtube or threads.
`createdAt`	body	integer (int64)	—	CreatedAt is unix seconds when the post was added, server-assigned and never rewritten.
`error`	body	string	—	Error is the exact reason the last publish attempt failed — the honest record behind a "failed" status, never a faked success.
`id`	body	string	—	ID is the server-assigned post id ("cal_" + 128 random bits).
`publishedAt`	body	integer (int64)	—	PublishedAt is when the publish succeeded; 0 until it does.
`scheduledAt`	body	integer (int64)	—	ScheduledAt is the unix publish time; 0 leaves the post a draft, and any value makes it "scheduled" for the durable sweep to pick up.
`status`	body	string	—	Status is draft, scheduled, published, failed or canceled.
`title`	body	string	—	Title is the post's internal label, capped at 1024 bytes.
`updatedAt`	body	integer (int64)	—	UpdatedAt is unix seconds of the last write, server-assigned.

MCP reaches marketing through the marketing tool, which names its 35 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,

         "arguments": {
