About
Lets any AI agent post to TikTok, Instagram, YouTube, X, LinkedIn, Bluesky, Telegram, Mastodon and Discord through a single post_to_social tool. Connect an account once, then publish everywhere.
README
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?utm_source=github&utm_medium=readme&utm_campaign=quickstart 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.
