7 Best Social Media MCP Servers for Claude and ChatGPT (2026)

Most people still copy a caption from Claude, open five tabs and paste it into each network by hand.

That workflow is over.

A social media MCP server lets Claude or ChatGPT publish, schedule and read analytics on your accounts directly. You write one prompt and the post goes out on LinkedIn, Instagram, TikTok and YouTube.

If you're:

• a founder posting every day,
• an agency managing dozens of client accounts,
• or a developer building an AI agent that needs to post,

you need to pick the right server. They are not all the same.

Quick answer: Blotato is the best social media MCP server if you want AI content creation and publishing in one place. Zernio is the best if your agent also has to answer comments and DMs, and its free tier covers 2 accounts. Buffer is the easiest free start.

What a social media MCP server actually does

MCP (Model Context Protocol) is the standard that lets an AI assistant call external tools. A social media MCP server exposes tools like create_post, schedule_post or get_analytics to Claude, ChatGPT, Cursor or any MCP client.

The difference between servers is not the protocol. It's four things:

• Publish or only read. Some servers only pull analytics. All 7 in this list publish.
• Hosted or local. Hosted servers give you a URL and an OAuth login. Local ones run with npx on your machine.
• Reads beyond posts. Analytics, comments and DMs. This is what lets an agent actually manage an account, not just push content.
• Pricing unit. Per account, per channel or per "profile" (a group of accounts). This changes the bill a lot once you pass 5 accounts.

If you need the raw REST APIs instead of MCP, I compared those in Top 5 Social Media APIs for Developers in 2026.

Best MCP server by network

LinkedIn MCP

LinkedIn has no official MCP server. All 7 servers here publish to LinkedIn through LinkedIn's official API, which is safer than the open-source scrapers that log in with your session. Blotato publishes to LinkedIn but doesn't return LinkedIn analytics.

Instagram MCP

All 7 publish to Instagram Business and Creator accounts. For comments and DMs, use Zernio, Vista Social, Ayrshare, Upload-Post or Blotato. PostFast handles comments but not DMs.

TikTok MCP

All 7 publish to TikTok. On Upload-Post, TikTok needs a paid plan. For TikTok comments, look at Zernio or PostFast.

YouTube MCP

All 7 upload to YouTube. Zernio, Ayrshare and Upload-Post can also read YouTube comments.

Reddit MCP

Only Ayrshare, Upload-Post and Vista Social publish to Reddit today. Zernio lists Reddit as temporarily unavailable.

X (Twitter) MCP

All 7 post to X. Watch the extra cost: Vista Social charges a $29/mo add-on and Zernio passes through X's API rates.

How to connect a social media MCP server to Claude

In the Claude app, open Settings → Connectors, search for the server in the directory (Blotato, Upload-Post and PostFast are listed) or click Add custom connector and paste the server URL. Then sign in with OAuth.

In Claude Code, add a hosted server with one line:

claude mcp add --transport http zernio https://mcp.zernio.com/mcp
claude mcp add --transport http buffer https://mcp.buffer.com/mcp

In ChatGPT, add it as a custom connector (developer mode) with the same URL.

Then test with a prompt like: "Schedule this LinkedIn post for tomorrow at 9:00 and show me last week's analytics."
