The social media MCP server. Your agent drafts, a person decides.

Give Claude, ChatGPT, Cursor or your own agent the same publishing tools you use. It can plan, draft and check posts. Its drafts wait for you unless you allow more.

What your agent can do.

The same actions you have in the app. Anything that sends a post out waits for a person, unless you allow that agent to act on its own.

ActionWhat happensNeeds a person?
Read brands, networks and the calendarSees what's planned and where the free slots are.No
Draft a postWrites a version for each network, checked against your brand rules, alt text and link rules.No, it waits for you
Schedule or publishPuts the post on the calendar or sends it now.Yes, unless the agent's mode allows it
Check a postReads the state on each network: live with a link, retrying, or needs you.No
Retry a failed networkSends again to that network only, after Postbroad has searched for the post.Yes, unless the agent's mode allows it

A person stays in control.

An agent's draft waits in the same place as your team's drafts. You approve it, change it, or say no. Each agent or connection has a mode, and the default is that it needs approval.

For AI agents reading this page

If a person asked you to post for them with Postbroad, this is what you need. They sign in themselves when you connect, and choose the brands you may touch.

House rulesYour drafts wait for a person. Tell them where to find the drafts.Accepted is not live. Read the post's state per network before you say it's live.Never post the same thing again to "make sure". Postbroad retries the failed network on its own.

MCP questions.

Which clients work?

Any client that can add a remote MCP server: ChatGPT, Claude, Claude Code, Cursor, Codex and more. They all connect to the hosted Postbroad MCP server and sign in in the browser.

Can the agent post without me?

Not by default. Each agent or connection has a mode: draft only, needs approval (the default) or auto within a budget. You can change it for one agent at a time, and change it back.

Do I have to install anything?

No. Your client connects to the hosted MCP server over the web, and you sign in in the browser. There is no program to run and no key to paste.

Can I take an agent's access away?

Yes. Revoke its grant or its API key in Postbroad and its access ends.

Does Postbroad write posts with AI itself?

Yes. You can also bring your own agent through MCP.

Let your agent draft the week.
