MCP Social Media Integration: The Complete Guide

Published 2026-03-20 by InfiniteApps

The Model Context Protocol (MCP) is transforming how AI assistants interact with external services. This guide covers everything you need to know about using MCP for social media publishing.

What is MCP?

MCP (Model Context Protocol) is an open standard created by Anthropic that allows AI assistants to connect to external tools and services. Instead of copying and pasting between apps, your AI assistant can directly take actions — like publishing a social media post.

How MCP Works for Social Media

When you install an MCP server like SendIt, your AI assistant gains access to 100+ tools:

Quick Start: Claude + SendIt MCP

The most common setup is Claude Desktop with the SendIt MCP server:

  • Create a free account at sendit.infiniteappsai.com
  • Get your API key from Settings > API Keys
  • Add to Claude Desktop's MCP config: command npx, args ["-y", "sendit-mcp"], env SENDIT_API_KEY=your_key
  • Restart Claude — you now have 100+ social media tools

    • 32 Supported Platforms

    SendIt's MCP server supports publishing to 32 platforms:

    Example Conversations

    Once set up, social media management becomes conversational:

    "Post to LinkedIn: Just shipped our v3.0 release with 32 platform support!"
    "Schedule a thread on X for tomorrow at 10am: Here are 5 lessons from building an AI-native product..."
    "What were my top 3 posts this week by engagement?"
    "Upload this image and post it to Instagram with relevant hashtags"

    If you prefer programmatic access over MCP, SendIt also offers a REST API available on all plans (including free). API documentation: OpenAPI spec.
