Paper for ChatGPT and Codex

Paper connects your designs, agents, code, and data on a single canvas built on web standards. This plugin connects ChatGPT (and Codex) to Paper's hosted MCP server at https://mcp.paper.design, so your agent can read and write your design files after you sign in with your Paper account.

No desktop install is required: everything runs through the remote server.

Features

  • Read designs: Inspect artboard structure, screenshots, computed styles, JSX output, and text content.
  • Write to the canvas: Create artboards, add or replace HTML nodes, update styles, set text, and duplicate elements from a prompt.
  • Export: Export artboards as images or PDFs.
  • Design systems: Read and write design tokens.

Install

  • ChatGPT / Codex: search for "Paper" in the Plugin Directory and install it, then sign in with your Paper account when prompted. Before it is listed: Plugins, the plus button, Add custom MCP server, URL https://mcp.paper.design, OAuth authentication.
  • Cursor / Grok Bot: install Paper from the Cursor Marketplace or Connect Apps. In the Cursor IDE with Paper Desktop installed, prefer the Paper Desktop plugin instead; it is faster and acts on the file you have open.

Package layout

This folder is a portable Agent Plugins package:

  • plugin.json: identity and listing metadata (OpenAI-specific fields under extensions.com.openai).
  • mcp.json: the remote MCP server, strictly per the Agent Plugins schema. OAuth is not declared here: Codex's parser rejects servers with extra keys, and clients discover the authorization server from the MCP endpoint itself (401 + resource_metadata). Pick OAuth in the portal's Connect panel when submitting.
  • assets/: listing icon.

Run bun run pack:chatgpt from the repository root to produce the ZIP uploaded to the OpenAI plugin submission portal. The ZIP contains only plugin.json, mcp.json, and the referenced icons; this README is for the repo, not the listing.
