The AI social media manager that posts for you.
Tell it what you want in plain English. Your agent writes the posts, tailors them for 7 social networks, and publishes them on schedule — while you and your team stay in charge.
Runs on an open-source social media MCP server — works with Claude, ChatGPT, Cursor and any Model Context Protocol client.
Announce our new feature that helps teams schedule posts smarter.
One prompt in. Seven networks out.
Up and running in three steps
No code. No configuration. Most people publish their first post in under five minutes.
- 1Step 01
Connect your accounts
Link X, LinkedIn, Instagram and the rest — one click each. We keep them safely connected so you never re-enter a password.
- 2Step 02
Tell your agent what you want
Type it in plain English — “announce our launch on Friday”. Your agent writes a polished post for every network: right tone, right length, right hashtags.
- 3Step 03
It posts and manages for you
Your agent schedules each post at the best time, publishes it automatically, and keeps the queue full — even while you sleep.
Your agent does the work. You keep control.
See your agent's plan at a glance
Everything your agent schedules lands on a visual calendar. Drag anything around, move a post, or clear a day — you always have the final say.
One idea, seven voices
The same news reads differently on LinkedIn and X. Your agent rewrites it for each network — character limits, line breaks, hashtags and tone — so you never sound copy-pasted.
Your brand, remembered
Teach your agent your tone, colours and go-to phrases once. Every post it writes comes out sounding like you.
Let your team manage it with you
Invite teammates into a shared workspace. They can draft, schedule and approve the agent's posts alongside you — one calendar for everyone, one bill.
It only posts what you allow
Accounts connect through each network's official sign-in — we never see or store a social password — and you can review every draft first. Disconnect any account with one click, anytime.
Connect the AI you already use — or build on the API yourself
One command connects ChatGPT, Claude or Cursor so they can post through PostMCP. Prefer to build it yourself? A REST API for all seven networks lets you wire publishing into your own product or automations. Neither is required — the built-in agent does everything on its own.
npx @postmcpai/server/v1/postsA social media MCP server for every AI assistant
PostMCP is an open-source social media MCP server — a Model Context Protocol server that turns social publishing into typed tools your AI assistant can call. One command gives Claude, ChatGPT, Cursor, VS Code or your own agent the ability to draft, schedule and publish to LinkedIn, X (Twitter), Facebook, Instagram, Threads, Bluesky and YouTube Shorts.
No scheduler tab, no API client, no per-assistant plugin. The tools are discovered at connect time, so the same server works across every MCP client — and the same posts show up in the calendar, the REST API and your team's queue.
16 typed publishing tools
Schedule, publish, retry, reschedule, read the queue, check token health, generate images — split into read-only and mutating so approval prompts stay meaningful.
stdio and streamable HTTP
One binary, two transports. Local desktop and IDE clients spawn it as a subprocess; remote connectors get a hosted URL with OAuth 2.0 discovery.
The model never holds a credential
Social OAuth tokens stay encrypted in the backend. Your API key lives in the server process. The model sees tool names, arguments and results — nothing else.

}Your agent’s social queue, in your pocket
The Companion app is the same workspace your MCP client publishes into — the queue, the calendar, the agent — built for the moments you are away from the keyboard. It is in a closed beta on TestFlight and Google Play: apply below, pick your platform, and the download links arrive by email once an admin approves you.
The whole queue, one thumb
Every scheduled post across your workspaces, by day. Drag one to a new slot, retry a failed one, or pause a network from the lock screen.
Push the moment it matters
Published, failed, token expiring, teammate needs an approval — a notification with the fix one tap away, not a dashboard you remember to check.
Compose and publish with media
Write once, attach photos or a Short from your camera roll, and publish to LinkedIn, X, Threads, Bluesky, Facebook, Instagram and YouTube Shorts.
Your agent, in chat form
“Announce the launch on Friday.” Read what it drafted, approve it, and watch it land in the calendar — the same agent your MCP client talks to.
- Same account as the web dashboard
- Face ID / fingerprint unlock
- No plan or checkout inside the app

Guides to running social media through an AI agent
What a social media MCP server is, how to wire one into Claude, ChatGPT or Cursor, and what to automate before it starts posting for the sake of posting.
How to automate social media posts with Claude
Every screen you will actually see, in order: the sign-in page, the channel connection, the MCP server URL, Claude’s custom connector dialog, and the first post going out. Roughly five minutes end to end, most of it waiting on OAuth.
What is an AI social media manager?
The phrase is used for everything from a caption generator to a fully autonomous account. Here is what a real AI social media manager does, where the line with a human sits, and what to check before you trust one with your accounts.
What is a social media MCP server?
Schedulers give people a calendar. APIs give programs an endpoint. An MCP server gives an AI assistant a set of typed tools it can decide to call — and that third thing is what changes how social publishing gets done.
Frequently asked questions
The things people ask before signing up — in plain English.
None. You tell your agent what you want in plain English and it does the rest — writing, scheduling and publishing. You can review every draft before it goes out, and nothing is posted without your say-so.
Yes. Give your agent one sentence, a link or a changelog and it writes a version for each network, checks the limits, schedules it and publishes to your real accounts. The only thing it never skips is your approval — every publish waits for a yes, so automatic never means unsupervised.
X (Twitter), LinkedIn, Instagram, Facebook, Threads, Bluesky and YouTube Shorts — all from one place, with one click. Your agent adapts each post to the network it is going to.
One credit = one published post. The free plan includes 20 every month, forever, with no card required. Your live balance and usage sit in your dashboard billing tab.
Yes. There are no contracts and no lock-in — cancel from your billing tab whenever you like, and the free plan never expires.
Channels are authorised through each platform's official OAuth 2.0 sign-in — we never see or store your social passwords. Access tokens are encrypted at rest, and you can revoke any channel instantly from your dashboard.
Both. One command connects ChatGPT, Claude, Cursor or any MCP-capable client so it can publish through PostMCP, and a REST API covering all seven networks lets you wire publishing into your own product or automations. Neither is required to use the app.
It is a Model Context Protocol server that exposes social publishing as typed tools an AI assistant can call — create a post, schedule it, publish it, retry a failure, read the queue, check which account tokens are expiring. The assistant discovers the tools automatically and picks the right ones from a plain-English instruction, so you describe the outcome instead of operating a scheduler. PostMCP ships 16 such tools across seven networks.
For Claude Desktop, Cursor and VS Code it is a five-line JSON block pointing at "npx -y @postmcpai/server" plus an API key from your dashboard — restart the client and the publishing tools appear. Claude.ai and ChatGPT are web clients, so they connect to a hosted copy of the same server over HTTPS, either as a remote MCP connector or as Custom GPT Actions built from its OpenAPI schema.
Not for the app, and not for local AI clients — npx fetches and runs the MCP server on demand, so there is nothing installed permanently. Hosting is only needed for browser-based clients like Claude.ai and ChatGPT, which cannot spawn a local process. The server is MIT licensed and published on npm as @postmcpai/server, so you can host it anywhere that runs Node.
