Using the MCP Tools

Creating Posts

The create_post tool lets you create and post content to social media platforms using natural language instructions:

{
  "instruction": "Post about the latest AI developments in healthcare",
  "platforms": ["twitter", "mastodon", "linkedin"],
  "postImmediately": false
}

This tool will:

Process your natural language instruction
Research relevant information if needed
Generate appropriate content for each platform
Either post immediately or return drafts for your approval

Researching Topics

Use the research_topic tool to gather information before creating posts:

{
  "topic": "artificial intelligence ethics",
  "includeHashtags": true,
  "includeFacts": true,
  "includeTrends": true,
  "includeNews": true
}

This will return relevant information about your topic, including popular hashtags, key facts, trending discussions, and recent news.

Getting Trending Topics

The get_trending_topics tool helps you stay current with what's popular on social media:

{
  "platform": "twitter",
  "category": "technology",
  "count": 5
}

This returns the top trending topics from your specified platform and category, which you can use to inform your content strategy.

Features and Capabilities

The Social Media MCP Server offers:

Multi-platform Publishing: Post to Twitter/X, Mastodon, and LinkedIn with platform-specific formatting
AI-Powered Content: Generate engaging content using multiple AI models
Research Integration: Automatically research hashtags, trends, facts, and news
Rate Limit Management: Handle API rate limits with queuing and fallbacks

When creating posts, the server intelligently formats content for each platform, ensuring optimal presentation whether you're posting to Twitter's character-limited environment or LinkedIn's professional audience.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "social-media-mcp" '{"command":"node","args":["path/to/social-media-mcp/build/index.js"],"env":{"TWITTER_API_KEY":"your_api_key","TWITTER_API_SECRET":"your_api_secret","TWITTER_BEARER_TOKEN":"your_bearer_token","TWITTER_ACCESS_TOKEN":"your_access_token","TWITTER_ACCESS_SECRET":"your_access_secret","TWITTER_OAUTH_CLIENT":"your_oauth_client","TWITTER_CLIENT_SECRET":"your_client_secret","MASTODON_CLIENT_SECRET":"your_client_secret","MASTODON_CLIENT_KEY":"your_client_key","MASTODON_ACCESS_TOKEN":"your_access_token","LINKEDIN_CLIENT_ID":"your_client_id","LINKEDIN_CLIENT_SECRET":"your_client_secret","LINKEDIN_ACCESS_TOKEN":"your_access_token","ANTHROPIC_API_KEY":"your_anthropic_key","OPENAI_API_KEY":"your_openai_key","BRAVE_API_KEY":"your_brave_key"},"disabled":false,"autoApprove":[]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "social-media-mcp": {
            "command": "node",
            "args": [
                "path/to/social-media-mcp/build/index.js"
            ],
            "env": {
                "TWITTER_API_KEY": "your_api_key",
                "TWITTER_API_SECRET": "your_api_secret",
                "TWITTER_BEARER_TOKEN": "your_bearer_token",
                "TWITTER_ACCESS_TOKEN": "your_access_token",
                "TWITTER_ACCESS_SECRET": "your_access_secret",
                "TWITTER_OAUTH_CLIENT": "your_oauth_client",
                "TWITTER_CLIENT_SECRET": "your_client_secret",
                "MASTODON_CLIENT_SECRET": "your_client_secret",
                "MASTODON_CLIENT_KEY": "your_client_key",
                "MASTODON_ACCESS_TOKEN": "your_access_token",
                "LINKEDIN_CLIENT_ID": "your_client_id",
                "LINKEDIN_CLIENT_SECRET": "your_client_secret",
                "LINKEDIN_ACCESS_TOKEN": "your_access_token",
                "ANTHROPIC_API_KEY": "your_anthropic_key",
                "OPENAI_API_KEY": "your_openai_key",
                "BRAVE_API_KEY": "your_brave_key"
            },
            "disabled": false,
            "autoApprove": []
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
