MCP

Post to Bluesky from your AI assistant

Connect PostNext to Claude, ChatGPT, Codex or Cursor and your assistant can draft, schedule and publish to Bluesky through the official API, with every post…

Connect PostNext

How it works

  1. Connect Bluesky to PostNext

    Sign in to PostNext and connect your Bluesky account once. PostNext holds the connection, so no token ever reaches your assistant.

  2. Add PostNext to your assistant

    Add https://mcp.postnext.io/api as an MCP server in Claude, ChatGPT, Codex or Cursor, then approve the sign-in screen once.

    {
  "mcpServers": {
    "postnext": {
      "url": "https://mcp.postnext.io/api",
      "transport": "http"
    }
  }
}

  3. Ask for the post

    Describe what you want in plain language. The assistant drafts it and schedules it through PostNext, and you can review it in the calendar before it publishes.

What you can ask

  • Draft three Bluesky posts about our launch and schedule them for Tuesday morning.
  • What is the best time to post on Bluesky for this account?
  • Show me how last week's Bluesky posts performed.

What the assistant can do on Bluesky

  • Generate a one-time link to authorise a new social channel.
  • Draft a new post (won't auto-publish).
  • Move a draft into the publish queue at a future time.
  • Read your queued posts before they go out.
  • Fetch likes, comments, shares and impressions for a published post across every connected platform.
  • Recommend the best (dayOfWeek, hour) slots for the next post on a given platform, ranked by engagement over the past 90 days.

Frequently asked questions

Do I need a paid plan?

No. The free plan gives you read access and draft creation. Only get_account_health (the 30-day analytics summary) requires a paid plan: Basic, Pro, Teams or Business.

How do I revoke access?

Disconnect from your AI client's settings, or open your account page on PostNext and remove the client. Tokens also auto-expire after 30 days of inactivity.
