Why is the plugin named Posty?

Posty is Postemi's sister brand in Hungary, on the same platform. Postemi has no own listing in the Claude directory yet. You sign in with your Postemi account.

Which Postemi plans work with Cowork?

MCP, the CLI and the REST API are part of the Pro, Creator and Team plans. Every plan starts with a 7-day free trial.

Does Postemi write the posts, or does Cowork?

Cowork writes them. Postemi has no built-in AI writer, on purpose: it connects your accounts, schedules and publishes.

Can Cowork publish without asking me?

It can, if you tell it to post now. Ask for drafts or scheduled posts instead, and check them in the Postemi calendar, where you can edit, move or delete them before they go out.

What it can do

What can Claude Cowork do with Postemi?

Claude Cowork gets the same Postemi tools in every workspace it connects to. It writes; Postemi schedules and publishes.

Draft, schedule or publish

Claude Cowork creates a post as a draft, schedules it for a time you name, or publishes it right away. Ask for a draft when you want to check it first.

Preview per account

Before it creates anything, Claude Cowork can show what would go out on each account: the text, the media and the character count.

Reads your calendar

Claude Cowork sees what is already scheduled, in your time zone, so it can find a free slot or move a post.

Knows each platform's rules

Postemi tells Claude Cowork the character limit and the options of every connected account before it writes.

The MCP server

What is the Postemi MCP?

MCP (Model Context Protocol) is an open standard that lets an AI agent use outside tools. Postemi runs a hosted MCP server at https://mcp.postemi.com/mcp. Claude Cowork connects to it, and from then on it can list your channels, read your calendar and create posts in your Postemi account.

The server runs on Postemi's side, so there is nothing to install for it. You sign in to Postemi in the browser, or use an MCP key, and that decides the workspace Claude Cowork works in. Your social accounts stay connected in Postemi itself: Claude Cowork never sees their passwords.

Postemi has no built-in AI writer, on purpose. Claude Cowork writes the posts, Postemi schedules and publishes them.

How Claude Cowork uses Postemi

Once Postemi is connected, Claude Cowork finds the tools by itself and calls them when you ask for a post.

Reads your connected accounts and each one's rules
Checks the calendar and your time zone before it picks a time
Can show a preview per account before it creates a post
Saves a draft, schedules, or publishes now, as you asked
Adds images and video from a link, or from an upload link you open
