}Call posts.fill_step
Write what a post is built from, its name and its own copy — ‘here’s what this post should say’, ‘this post is built from Tuesday’s episode’, ‘rename this post’. Its copy is what every destination’s version is shaped from, so write it before each destination’s version. It saves the draft only; nothing is published or sent. Not for one destination’s own version — that is posts.save_variants.
Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with workspace_ambiguous and lists the choices — offer them, never pick one.

}Authorizations
An API key minted at Settings › API & MCP. Send it as Authorization: Bearer <key>. A key carries its holder's own permissions, resolved on every call — revoking a membership closes the key's reach immediately. Keep it in an environment variable (GOOSY_API_KEY), never in a committed file.
Headers
Your key for this write: send the same key when you retry and the first result comes back instead of a second action. Keys are honoured for at least 24 hours. 1–200 visible ASCII characters. Replaces the idempotency_key body field, which still works until 2026-12-31; this action needs a key on one of the two, and the header is the one to send.
200Body
Response
The call was admitted and dispatched. ok says whether the tool succeeded — a refusal the tool itself produced is still a 200, exactly as it is a successful JSON-RPC result over MCP.
- Option 1
- Option 2
The tool ran and answered.
