Hookpost MCP server, CLI and n8n node

Hookpost by Hookstep. A social media scheduler you can drive from Claude, Cursor, VS Code, Gemini CLI and other AI assistants. (Not related to the Shopify Flow app called HookPost.)

What it does

Hookpost runs a hosted MCP server. Connect your AI assistant to it once, and the assistant can:

• list the social channels connected to your Hookpost workspace
• read each network's rules: character limits, media rules and the settings a post needs
• save posts to your Hookpost calendar as drafts, as scheduled posts, or publish them now
• list what is scheduled between two dates, and change the network settings of a post that has not gone out yet
• import an image or video from a public URL into your media library

Posts from an assistant land in the same calendar as posts written in the app, with an MCP badge, and go through the same checks as the editor. If a post breaks a network's rules, the assistant gets the reason back. There is no delete tool: deleting, and editing the text or date of an existing post, stay in the app.

There is nothing to install for the MCP server. It is one URL:

https://hookpost.hookstep.in/api/mcp

Your workspace API key goes in an Authorization: Bearer header. Copy the key from Settings → Developers in Hookpost. For a client that cannot send headers, put the key in the path instead: https://hookpost.hookstep.in/api/mcp/YOUR_API_KEY.

Behind a gateway that keeps the Authorization header for itself, such as Smithery, send the key as x-hookpost-api-key: YOUR_API_KEY instead (the raw key; a Bearer prefix is also accepted). If a request carries both headers, Authorization wins.

Treat the key like a password. It gives full access to your workspace's channels and posts, so keep it out of shared configs and public repos.

Set it up in your assistant

Claude Code

claude mcp add --transport http hookpost https://hookpost.hookstep.in/api/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Check it with claude mcp list.

Or install the Hookpost plugin, which adds the server plus a skill that tells Claude to check each network's rules and save drafts first. Claude Code asks for your API key once and keeps it in your system's credential store:

/plugin marketplace add jatinder14/hookpost-mcp
/plugin install hookpost@hookpost

Claude (claude.ai and Claude Desktop)

Go to Customize → Connectors → + Add → Add custom connector, paste the URL with your key in the path, and choose no sign-in:

https://hookpost.hookstep.in/api/mcp/YOUR_API_KEY

Claude adds remote servers as connectors, not through claude_desktop_config.json. On Claude's free plan you get one custom connector. If Claude Desktop can't connect that way, use th
