Post to Instagram from an agent

PostWharf ships a Model Context Protocol server, so Claude and other MCP clients can draft, queue and check Instagram posts as tools rather than as scraped UI.

Connect it

claude mcp add --transport http \
  wharf https://mcp.postwharf.com/mcp \
  --header "Authorization: Bearer $POSTWHARF_KEY"

The key scopes every call to one workspace, so an agent can only ever act on the brand you hand it. Find it in the dashboard under API keys.

What Instagram accepts

2,200 characters, counting the caption. Up to 10 images or 10 videos per post — and the two can travel together.

Read from the table the API enforces, so a post over 2,200 is refused when you create it rather than truncated on the way to Instagram.

Asking for it in practice

# to Claude, with the connector attached
"Draft three Instagram posts about the new release,
 queue the best one for Tuesday morning,
 and tell me once it is live."

The agent drafts and queues; the delivery receipt tells you what actually published. Requires a Business or Creator account linked to a Facebook Page.
