What is the best MCP server for social media posting?

It depends on what you need posted. If the post needs a video or image made first, Siren makes it in your brand and posts it from the same MCP server. If you already have the content, a posting-first server with more networks, like Blotato or Post Bridge, is the better fit, and for text threads Typefully's MCP server is built around writing.

Siren makes launch videos, ad creatives and captions in your brand from one prompt, and posts them to X, LinkedIn and YouTube (TikTok with your OK on each post). One video is $9.99; plans are Spark $19, Pro $49 and Scale $149 a month, and Siren works inside Claude, Cursor and ChatGPT over MCP. Updated 3 Oct 2026.

Make a video for $9.99

Step by step

  1. List what you post. Text, images, videos? If it is mostly video of your product, you need a server that can make video, not only schedule it.
  2. List where you post. Count the networks. Posting-first servers cover the most networks; Siren covers X, LinkedIn and YouTube, and TikTok with your OK on each post.
  3. Check how it signs in. Prefer OAuth over pasting API keys into your agent's config.
  4. Check what it shows you before posting. A good server lets the agent show you the post before it goes out.
  5. Try one real post. Connect it, ask for one post, and see what comes out.
