Postpone exposes a Model Context Protocol (MCP) server that lets AI tools work directly with your Postpone account. Once connected, you can ask an AI agent to create posts, schedule content, browse your media library, and review analytics — all in natural language, without leaving the conversation.
What Is MCP?
Model Context Protocol (MCP) is an open standard that lets AI applications connect to external tools and data. Postpone runs a hosted MCP server, so any MCP-compatible client — Claude, ChatGPT, Gemini, Mistral Vibe, Perplexity, Grok, Muse, OpenClaw, Cursor, Zapier, n8n, Raycast, and more — can securely act on your behalf inside Postpone.
When you connect a client, the AI agent gains access to a set of Postpone tools it can call when you ask it to. You stay in control: the agent only acts when you ask it to, and changes appear in your Postpone account just as if you'd made them yourself.
What You Can Do
With Postpone connected to an AI agent, you can:
- List your connected social accounts and see which ones have posts scheduled.
- Create and schedule posts across all your supported platforms.
- Add posts to your queue — skip picking a time and let the post take the next open slot in the account's Account Schedule.
- Write posts from a source — point the agent at a blog post or article URL and have it draft posts for several platforms at once.
- Attach media from your Postpone content library, such as the last video you uploaded.
- Review your queue of scheduled and draft posts.
- Find your best posts — rank what you've published by likes, views, shares or any other metric a platform reports.
- Compare accounts and periods using totals and per-post averages over any date range.
- Track follower growth over time, across one account or all of them at once.
Example Prompts
These work in any connected client. Copy one to get started:
"List all my connected Postpone social accounts."
"Look at my recent posts on X to learn my usual topics and tone, then draft a new post and schedule it for tomorrow morning."
"Write a post for X about topic and add it to the next open slot in my queue."
"Fetch the blog post at URL, write a post for X, Threads, and Bluesky, and schedule all three in Postpone."
"Schedule a TikTok video using the last video I uploaded to my Postpone content library."
"Show me my scheduled posts for this week so I can review what's coming up."
"What was my top performing post on LinkedIn in the last 7 days?"
"How many followers did each of my accounts gain last month?"
"Compare my Instagram and TikTok engagement for August — totals and averages per post."
For more, open the Prompt Library in Postpone under Settings → AI Agents & MCP. It has ready-made prompts for planning, creating, repurposing, and analyzing posts, with fill-in fields and the platforms you've connected filled in.
How Connecting Works
You connect a client to Postpone in one of two ways, depending on what the client supports. Each setup guide tells you which method to use.
OAuth
Most clients (Claude, ChatGPT, Gemini, Mistral Vibe, Perplexity, Grok, Cursor, and others) use OAuth. You add Postpone as a custom connector using the MCP server URL, then sign in to Postpone and approve access in a pop-up window. No API key required.
The Postpone MCP server URL is:
https://api.postpone.app/mcp
API Key
Some developer and automation tools (Muse, n8n, and other API-key clients) authenticate with a Postpone API key sent as a Bearer token. You create a key in Postpone, then add it to the client's configuration alongside the server URL.
You can create and manage API keys on the API Settings page. API access requires a plan that includes it and a confirmed email address.
For API-key clients, the server configuration looks like this:
{
"mcpServers": {
"postpone": {
"url": "https://api.postpone.app/mcp",
"headers": {
"Authorization": "Bearer API_KEY"
}
}
}
}
Replace API_KEY with the key you created.
Before You Start
To use Agents & MCP you'll need:
- A Postpone account with at least one connected social account — the agent can only post to accounts you've already linked.
- A supported MCP client (see the setup guides below).
- For API-key clients, a plan that includes API access.
You can set up connectors from the Agents & MCP settings page in Postpone, which provides the same step-by-step instructions for each tool.
