postwire-mcp

Let your AI agent post to social media. An MCP server for PostWire — give Claude, Cursor, or any agent the ability to publish to TikTok, Instagram, YouTube, X, LinkedIn, Bluesky, Telegram, Mastodon & Discord with one tool call.

Quick start

Get a free API key at https://postwire.io/dashboard.html and connect your accounts.
Add to your MCP client (e.g. Claude Desktop / Cursor):

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

Now your agent has two tools:

`post_to_social` — { platforms: ["x","tiktok"], text, video_url?, photo_url? }
`list_platforms` — list supported networks.

Why PostWire

One API + a real MCP server to post everywhere. Flat per-brand pricing (50 brands for $99 — vs Ayrshare's ~$779). Free tier, no card.
