How to use Polyblog with ChatGPT, Claude and other AI assistants

Polyblog has an official connector for AI assistants such as ChatGPT, Claude, Muse, Grok and Perplexity. Once it is connected, you can ask the assistant about your Polyblog account in your own words. It can read and preview your posts, check which languages are missing translations, list the pages in your sitemap and browse your saved topic ideas. After you approve, it can save, edit, publish or delete posts, draft a text-only post with AI, create a blog and refresh topic ideas.

Connector URL: https://mcp.polyblog.io/mcp

When you connect, a Polyblog window opens: sign in with your usual Polyblog email and password and approve the access. You don't need an API key or any technical setup.

What you can ask

  • "Which languages of my blog are missing posts?"
  • "Write a draft post about choosing booking software, but don't publish it."
  • "Show my latest drafts and publish the one about pricing."

Posts drafted through an AI assistant are text only: cover images and the autopilot are available in Polyblog itself. AI drafting uses your Polyblog AI usage, and a deleted post cannot be recovered.

Connect Polyblog to your AI assistant

You add Polyblog once, then the assistant can use it in any chat. AI apps rename these menus often: Plugins, Connectors and Apps all mean the same thing.

ChatGPT

  • From the plugin directory (most plans): if Polyblog is listed, open Plugins in the sidebar (or Settings → Plugins), search for Polyblog, select Install and Connect, and sign in.
  • Add it yourself (ChatGPT Pro, Business, Enterprise and Edu, on the web): open Plugins, select + and Add custom MCP server, enter Polyblog as the name and paste the connector URL, choose OAuth sign-in, confirm and select Create as a plugin. Then install it and type @Polyblog in a chat. On Business, only an admin can add it. On Pro, a server you add yourself can only read, not change anything.

If you don't see Add custom MCP server, your plan doesn't include it: use the directory instead.

Claude

On claude.ai or in the Claude desktop app, open Customize (called Plugins in newer versions) → Connectors, select + Add → Add custom connector, enter Polyblog and paste the connector URL, select Continue, keep the recommended sign-in options and select Add. Then select Connect and sign in to Polyblog. It also works in the Claude mobile app afterwards.

  • Free plans can add one custom connector.
  • On Team and Enterprise plans, an owner adds it first in Organization settings → Connectors; then each member connects with their own Polyblog account.
  • If Polyblog is in Claude's connector directory, you can also add it from there.

Muse (Meta)

Muse is available in the United States, Canada, Japan and Singapore. In a Muse chat, ask: "Create a custom connector for Polyblog with the URL https://mcp.polyblog.io/mcp". Muse guides you through it: sign in to Polyblog when the window opens and allow access. Muse asks for your permission the first time it uses the connector, and every time before a sensitive action.

Grok

On grok.com, open Connectors (grok.com/connectors), select New Connector → Custom, paste the connector URL and sign in to Polyblog. On Grok Business, an admin adds the connector first in the xAI console; then each member connects it.

Perplexity

On Perplexity Pro, Max and Enterprise: open Plugins (or Customize → Connectors), select Add custom → Add MCP connector → Remote, enter Polyblog and paste the connector URL, choose OAuth, accept and select Add. Then select the new card to sign in to Polyblog.

Mistral Vibe (Le Chat)

Open Connectors, select + Add Connector → Custom MCP Connector, enter Polyblog and paste the connector URL, then select Connect and sign in to Polyblog.

Gemini and Microsoft Copilot

Gemini and Microsoft Copilot can't connect to Polyblog yet. We will update this page when they can.

AI agents that work for you

  • OpenAI Dots use the plugins of your ChatGPT account. Install Polyblog in ChatGPT first (see above), then open your dot's profile → Customize → Plugins, choose Polyblog and connect it. Dots are available on ChatGPT Pro (outside the EEA, the UK and Switzerland) and Business Premium.
  • Claude Duet uses the apps you have already connected in Claude: connect Polyblog in Claude first (see above). Duet is available on Claude Pro, Max and Ultra in the United States, with a waitlist.
  • Grok Bot can add Polyblog by its URL: ask your Bot to add the MCP server https://mcp.polyblog.io/mcp, or open Connect apps, add it and select Authorize to sign in. Then mention it with @.

You choose which actions an agent may take without asking you first.

For developers

In Claude Code:

claude mcp add --transport http polyblog https://mcp.polyblog.io/mcp

Then run /mcp to sign in. In OpenAI Codex:

codex mcp add polyblog --url https://mcp.polyblog.io/mcp
codex mcp login polyblog

In Cursor, add it to ~/.cursor/mcp.json:

{ "mcpServers": { "polyblog": { "url": "https://mcp.polyblog.io/mcp" } } }

In VS Code, run MCP: Add Server from the Command Palette, choose HTTP and paste the connector URL. Any other app that supports remote MCP servers with OAuth sign-in can use the same URL.

Privacy and security

  • The assistant only sees what your own Polyblog account can see, and only after you approve the connection.
  • Polyblog never shares your password with the AI app.
  • You can disconnect Polyblog at any time in the assistant's settings. Changing your Polyblog password also disconnects every AI app.

If something does not work

  • You can't find Polyblog in the app's directory: add it as a custom connector with the URL above.
  • The assistant asks for an API key or a client ID: leave those fields empty. Polyblog uses a normal sign-in instead.
  • The sign-in window shows an error: write to us here with the name of your AI app and what you see, and we'll help.
  • The assistant can no longer reach Polyblog: connect it again. A connection unused for about 90 days, and every connection made before you changed your Polyblog password, needs a new sign-in.
  • The assistant says it can't do something: the connector can only do what is listed above. Do the rest in the Polyblog app.
