AtriumKit

AtriumKit MCP server

AtriumKit makes interactive product demos, step-by-step guides and videos from one recording. Its hosted MCP server lets an AI assistant work on your demos for you: "rewrite the tooltips for a CFO", "translate it into German and publish", "which step loses the most viewers?".

This repository is documentation only. The server is hosted by AtriumKit, so there is nothing to install or run.

Full setup guide with screenshots: Connect Claude, ChatGPT or Cursor to AtriumKit.

Connect

Claude

Works in claude.ai, Claude Desktop and the Claude mobile apps.

1. Open Customize → Connectors and choose Add custom connector. On Claude Team and Enterprise, an Owner adds it under Organization settings → Connectors, then each member clicks Connect.
2. Paste https://app.atriumkit.com/mcp. Leave the OAuth client fields empty.
3. Click Add, then Connect.
4. On the AtriumKit page that opens, sign in, pick the workspace and what Claude may do, then click Allow access.

Claude Code

claude mcp add --transport http atriumkit https://app.atriumkit.com/mcp

Then run /mcp in Claude Code, pick atriumkit and choose Authenticate.

ChatGPT

Custom MCP servers need developer mode, which is available on some ChatGPT plans.

1. In ChatGPT settings, open Apps → Advanced settings and turn on Developer mode.
2. Add a custom MCP server named AtriumKit, paste the server URL and choose OAuth. Leave the client ID and secret empty.
3. Sign in to AtriumKit, pick the workspace and what ChatGPT may do, then click Allow access.

Cursor

Add this to ~/.cursor/mcp.json (every project) or .cursor/mcp.json (one project). Cursor asks you to sign in the first time it connects.

{ "mcpServers": { "atriumkit": { "url": "https://app.atriumkit.com/mcp" } } }

Other clients

Point any MCP client that supports Streamable HTTP at https://app.atriumkit.com/mcp. Clients that support OAuth discover the authorization server from https://app.atriumkit.com/.well-known/oauth-protected-resource/mcp. For a client or script that can only send a fixed token, create a personal access token in AtriumKit under Settings → AI assistants & MCP → Access tokens and send it as Authorization: Bearer . Tokens work only on the MCP server, never to sign in, and AtriumKit emails you when one is created.

Permissions

You choose these when you connect an app or create a token. Your workspace role still applies: a viewer's assistant can't edit, whatever was ticked.

What an assistant can do

List and read demos and screens; edit copy and steps; add choices; link navigation in clickable demos; rewrite copy with AI; translate; generate voiceovers; publish and unpublish; read analytics and leads; create personalized links; add demos to collections; read published guides; and search the knowledge base.

Plan limits apply as in the app: translations, voiceovers, personalized links and the knowledge base need Pro or Team, and AI rewrites and translations use the workspace's AI credits.

Every change an assistant makes shows in the demo's version history, marked like "Edits by Ana (via Claude)", and can be restored. Assistants see screens the way viewers do: blurred areas, redacted text and personal data on screenshots never go out.

Limits

• Each connection or token works in one workspace. Connect again to use another.
• Up to 120 requests a minute per connection or token.
• Up to 25 active tokens per workspace.

Disconnect

In AtriumKit, open Settings → AI assistants & MCP and click Disconnect next to an app or Revoke next to a token. It stops working right away.
