    In ChatGPT, open Settings, then Plugins under Integrations. Press Add and choose Add MCP server.

  2. 2

    Fill in the form

    Set Name to polyscribe, keep Type on Streamable HTTP and set URL to https://api.polyscribe.io/mcp. Leave the bearer token and header fields empty, then press Save.

  3. 3

    Turn it on and sign in

    Back on the MCPs tab, switch polyscribe on. Your browser opens Polyscribe: sign in and press Connect. When the browser says authentication is complete, close it.

  4. 4

    Use it

    In a new chat, ask for a rewrite, for example: rewrite this in a casual style.

Claude Code

Add the server, then sign in from inside Claude Code:

claude mcp add --transport http polyscribe https://api.polyscribe.io/mcp

Run /mcp, pick polyscribe and choose Authenticate. Your browser opens the same sign-in as above.

Codex

One setup covers Codex CLI, the Codex IDE extension and the ChatGPT desktop app, which share a config. Add the server:

codex mcp add polyscribe --url https://api.polyscribe.io/mcp

Then sign in. Your browser opens the same sign-in as above:

codex mcp login polyscribe

What it can do

  • rewrite_text

    Rewrites text in one of your writing styles. Spends credits: one per 500 characters of input.

  • get_rewrite

    Collects a long rewrite that was still running when rewrite_text returned.

  • list_styles

    Lists the built-in styles and the ones you trained, and which your plan covers.

  • get_account

    Shows your plan and the credits you have left.

A rewrite is charged when it starts and returned in full if it fails. Every rewrite made through a connector appears in your history in the app.

Other MCP clients

Any client that supports remote MCP servers with OAuth sign-in can connect with the same URL. API keys are for the REST API and do not work here.

Disconnecting

Every app you approve is listed under Connected apps. Disconnect one there and its next request is refused.
