Draft, schedule and publish X (Twitter) and LinkedIn posts in your own voice.
From the repo.
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 |
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.
/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 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"
Open Customize > Connectors, click +, choose Add custom connector, enter https://www.postel.app/api/mcp and sign in to Postel when asked.
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.
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.
