FeedHorizon

FeedHorizon MCP server

Let Cursor, Claude, ChatGPT and other AI assistants schedule and publish social media posts on X (Twitter), LinkedIn, Instagram, Bluesky, Pinterest and TikTok (TikTok in beta: private posts until TikTok's review).

FeedHorizon is a social media API and hosted MCP server. EU hosted (Frankfurt), the first 2 connected accounts are free.

• URL: https://feedhorizon.com/mcp (streamable HTTP)
• Sign-in: OAuth. Your assistant opens a FeedHorizon sign-in page the first time. An API key as Authorization: Bearer fh_… works too.
• Docs: https://feedhorizon.com/docs/guides/mcp
• Official MCP Registry: com.feedhorizon/mcp

What the assistant can do

• See your profiles and connected accounts
• Check a post against each network's rules (length, media, schedule) before it is saved
• Create drafts, schedule posts at a time, add them to your queue, publish now
• Read and set queue slots, duplicate, cancel and retry posts
• Import media from a URL or create an upload link
• Create a connect link so a client can connect their own account
• Search the FeedHorizon docs

The assistant can do nothing your account could not do through the REST API: same checks, limits and permissions.

Cursor

Add this to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "feedhorizon": {
      "url": "https://feedhorizon.com/mcp"
    }
  }
}

Cursor opens the FeedHorizon sign-in when you first use a tool. To use an API key instead, add "headers": { "Authorization": "Bearer fh_your_api_key" }.

Claude, ChatGPT and other clients

Add a custom connector / remote MCP server with the URL https://feedhorizon.com/mcp and sign in. Step-by-step guides for each client: https://feedhorizon.com/docs/guides/mcp
