The best social media MCP servers (2026), compared with prices

What makes an MCP social server "good"?

• It actually posts — a working MCP server with a publish tool the model can call.
• Connect once, post everywhere — one tool call fans out to many networks.
• Handles OAuth & platform approvals — the hard part (TikTok audit, Meta review, Google verification) is managed for you.
• Sane pricing — a price you can predict as you add networks and clients.
• A free tier — so an agent builder can try it without a card.
• Native per-platform writing — turns one prompt into the right post for each network, not the same text everywhere (which algorithms penalize).

PostWire vs the alternatives

The MCP ecosystem moved fast in 2026 and several good options exist — Buffer, Metricool, Hootsuite, Blotato, Typefully, Postiz and Upload-Post also have MCP servers that publish. PostWire pairs per-brand pricing and a free tier with server-side writing: as of Sept 2026, we couldn't find another hosted API that writes a different native post per network from one prompt, in one call. It ships Smart Distribute (generate_posts): from one prompt it writes the best native post per platform — SEO title/tags for YouTube, hook-first captions for TikTok, link-in-comment for LinkedIn — rather than blasting identical text everywhere.

Social media MCP servers compared: sign-in, free plan and price (Nov 3, 2026)

Each row read on the vendor's own MCP and pricing pages on Nov 3, 2026. Prices are monthly, billed monthly.

Where PostWire is ahead in this table: a free plan with no time limit that includes the MCP server and the AI writer; one flat price per business ($19 for 3 businesses, $29 for 10), so ten clients cost $29 instead of a fee per channel; sign-in with no key to copy, from both Claude's and ChatGPT's directories; and generate_posts, which writes each network's own version on the server.

How to use the PostWire MCP server

Add it to any MCP client (Claude Desktop, Cursor, an agent framework):

{
  "mcpServers": {
    "postwire": {
      "command": "npx",
      "args": ["-y", "postwire-mcp"],
      "env": { "POSTWIRE_API_KEY": "pw_live_xxx" }
    }
  }
}

Then the agent just calls the tool:

{
  "name": "post_to_social",
  "arguments": { "platforms": ["bluesky","telegram"], "text": "Shipping today 🚀" }
}
