Postel MCP server for X (Twitter) and LinkedIn

Draft, schedule and publish X (Twitter) and LinkedIn posts from Claude, Cursor and other MCP clients.

Postel is a writing and scheduling tool for people who post as themselves: founders, consultants and creators. Its hosted MCP server lets an AI assistant research high-performing X posts, draft posts and threads in your saved voice, and schedule or publish them to your X account and your personal LinkedIn profile once you approve.

This repository holds the public metadata for that server: the Claude plugin, the MCP Registry entry and setup instructions. The server itself is hosted by Postel; there is nothing to run locally.


Server URL	`https://www.postel.app/api/mcp`
Transport	Streamable HTTP
Authentication	OAuth 2.1 with dynamic client registration, or an API key as a bearer token
Registry name	`app.postel/postel`

Setup

Post research (search-viral-tweets) works without an account. For everything else you need a Postel account; connect your X account, your LinkedIn profile or both under Settings > Channels.

Claude Code plugin

/plugin marketplace add robinfaraj/postel-mcp
/plugin install postel@postel

Then run /mcp and sign in to Postel. The plugin adds the server and a postel-writing skill that teaches Claude the drafting and scheduling workflow.

Claude Code without the plugin

claude mcp add --transport http postel https://www.postel.app/api/mcp

Run /mcp to sign in. To use an API key instead:

claude mcp add --transport http postel https://www.postel.app/api/mcp --header "Authorization: Bearer pstl_YOUR_API_KEY"

Claude (web and desktop)

Open Customize > Connectors, click +, choose Add custom connector, enter https://www.postel.app/api/mcp and sign in to Postel when asked.

Cursor

Add this to your MCP settings (~/.cursor/mcp.json or .cursor/mcp.json in a project):

{
  "mcpServers": {
    "postel": {
      "url": "https://www.postel.app/api/mcp",
      "headers": {
        "Authorization": "Bearer pstl_YOUR_API_KEY"
      }
    }
  }
}

Create the key in Postel under Settings > API Keys. Keys start with pstl_ and are scoped to one workspace.

Other clients

Any client that supports remote MCP servers over Streamable HTTP works. Point it at the server URL above and either let it run the OAuth sign-in or send Authorization: Bearer pstl_YOUR_API_KEY.

What it does not do

It does not like, reply, follow, comment or send connection requests.
LinkedIn posts go to personal profiles only, not company pages.
Images, video, documents and LinkedIn first comments are added in the Postel editor, not through MCP.
Research searches Postel's indexed library of X posts, not live X.

Plans and limits

Research needs no account. Drafting and reading posts work on any plan, and AI generation counts against your monthly quota.
Scheduling and publishing need a paid plan or trial. See pricing.
API keys are limited to 60 requests per minute.
