Bring Sketch into your AI assistant — in Claude, ChatGPT, or your browser it can make on-brand content, plan campaigns and audit sites for you, directly. Same account, same brands.
First, grab an API key
Claude & ChatGPT authenticate with a Sketch key (starts with sk_). Create one in Developers.
Fastest — the Claude Code plugin
One-click install, your API key baked in — no copy-paste, no setup.
Or add it manually
Add Sketch as an MCP server with the Claude CLI (or add it under Settings → Connectors in the Claude app).
claude mcp add sketch https://sketch.protaige.com/api/mcp \ --header "Authorization: Bearer sk_your_key_here"
Ask Claude to “list my Sketch brands” or “make a LinkedIn post for <brand>”. It calls Sketch directly.
In ChatGPT, open Settings → Connectors → Add and paste the Sketch MCP URL:
https://sketch.protaige.com/api/mcp
Set the authorization header to Bearer sk_your_key_here, then enable the Sketch connector in a chat.
No setup. When you’re signed in, every Sketch page exposes its tools to an in-browser AI agent via navigator.modelContext — a WebMCP-aware browser or extension can operate Sketch in your own session, no key. See exactly which tools a page exposes and try one:
