PostPublish for Le Chat

Add PostPublish as a custom connector in Le Chat. Ask in plain words and it writes, checks and schedules posts to Facebook Pages, Instagram, Threads, X, LinkedIn and Telegram.

Set up Le Chat

  1. 1

    In Le Chat, open Intelligence, then Connectors.

  2. 2

    Choose to add a custom MCP connector.

  3. 3

    Enter https://postpublish.pro/api/mcp, then sign in to PostPublish.

Custom connectors may be limited to certain Le Chat plans.

Server URL: https://postpublish.pro/api/mcp. OAuth is recommended. If your client cannot do OAuth, create an API key in PostPublish (Settings, then API keys) and send it as a Bearer token; if it only runs local servers, use the stdio bridge with npx mcp-remote.

Example prompts

  • “Draft three posts about our spring menu and schedule them to Facebook, Instagram, LinkedIn and X for this week at 9:00.”
  • “Check this caption against Threads limits and tell me what to trim before scheduling.”
  • “Show everything scheduled for next week and flag days with no post.”
  • “Move tomorrow's Instagram post to Friday at 17:30.”

Troubleshooting

The connector or server does not show up.

Check that the URL is exactly https://postpublish.pro/api/mcp and that your version of Le Chat supports remote MCP servers. If it only supports local servers, use the stdio bridge (npx mcp-remote).

Sign-in loops or fails.

Make sure you can sign in to app.postpublish.pro in the same browser, and that your workspace's trial or plan is active. If it still fails, remove the connection and add it again.

A post is rejected.

Each network has limits (Threads 500 characters, Instagram 2,200, plus media rules). Ask the agent to preview first; it reports warnings before anything is created.

The agent cannot see my accounts.

Connect your Facebook Pages, Instagram, Threads, X, LinkedIn or Telegram accounts in the PostPublish app first, and check that your role or key can read and write posts.

Revoke access

  • Remove the PostPublish connection in Le Chat's MCP or connectors settings.
  • In the PostPublish app, open Settings, then AI agents, and revoke any key you created for this client. A revoked key stops working immediately.
  • To end an OAuth sign-in, remove the connector in the client. Leaving the workspace ends all access for that user.
