Connect Karou to Claude, ChatGPT and Cursor

Karou is an MCP server. You add it once to the AI you use, and from then on “make me a carousel” comes back as finished slides in the chat. This guide walks through each app.

Claude.ai, desktop and mobile

Claude signs in to your Karou account; there is no key to paste.

1. Create a free account at karou.si and set your password from the welcome email.
2. In Claude, open Settings → Connectors and choose Add custom connector.
3. Name it Karou and paste https://karou.si/mcp as the URL.
4. Click Connect, sign in to Karou and choose Allow.

The connector follows your account, so it works in the desktop and mobile apps too.

ChatGPT

1. Open Settings → Connectors (on some plans, developer mode has to be on).
2. Add a custom MCP server named Karou with the URL https://karou.si/mcp and authentication set to OAuth.
3. Sign in to Karou and choose Allow.

Claude Code

Create a key on the Connect page, then run once:

claude mcp add --transport http karou https://karou.si/mcp --header "Authorization: Bearer kru_live_…"

Cursor and VS Code

Add this to ~/.cursor/mcp.json (Cursor) or .vscode/mcp.json (VS Code), with the key from the Connect page:

{ "mcpServers": { "karou": { "url": "https://karou.si/mcp", "headers": { "Authorization": "Bearer kru_live_…" } } } }

The first prompt

Start a new chat and ask:

Make me an Instagram carousel with Karou: 5 slides on the three pricing mistakes I made with my first ebook. Use the bold template.

The AI writes a hook slide, one idea per slide and a closing slide, calls Karou, and shows you the thumbnails with a ZIP of PNGs and a PDF. Want a change? Say “make slide 3 shorter” and it re-renders the same carousel.

Every carousel is kept in your account under Carousels, and every call shows up under Usage.
