Medium MCP API Server
A Model Context Protocol (MCP) server that integrates with Medium's API to enable seamless content publishing and user account management from external applications. The Model Context Protocol provides a standardized way for AI models to interact with external services and APIs, allowing this server to serve as a bridge between AI assistants and the Medium publishing platform.

🔄 Integrating with the MCP Server
Example: Publishing a post with Node.js
const axios = require('axios');
const API_URL = 'http://your-domain.com';
const TOKEN = 'your_jwt_token';
async function publishPost() {
try {
// Create a draft post
const post = await axios.post(`${API_URL}/api/posts`, {
title: 'My Awesome Article',
content: '# Hello Medium\n\nThis is my first post published via the MCP API.',
contentFormat: 'markdown',
tags: ['api', 'medium', 'tutorial'],
publishStatus: 'draft'
}, {
headers: {
'Authorization': `Bearer ${TOKEN}`
}
});
// Publish the post to Medium
const published = await axios.post(`${API_URL}/api/posts/${post.data._id}/publish`, {}, {
headers: {
'Authorization': `Bearer ${TOKEN}`
}
});
console.log('Post published successfully!', published.data);
} catch (error) {
console.error('Error publishing post:', error.response?.data || error.message);
}
}
publishPost();
📅 Scheduled Publishing
The server supports scheduling posts for future publication. When creating or updating a post, include a scheduledAt field with an ISO timestamp:
{
"title": "Scheduled Post",
"content": "This will be published automatically.",
"scheduledAt": "2025-03-20T12:00:00.000Z"
}
The server will automatically publish the post at the specified time if Redis is configured.
🛡️ Security Considerations
- Always use HTTPS in production
- Rotate your JWT secret regularly
- Set up proper monitoring and logging
- Store sensitive data in environment variables or a secure vault
- Implement proper CORS policies
