Sign-in and Permissions

The connector uses Streamable HTTP and OAuth 2.1 with PKCE and dynamic client registration. Sign in to invitas when prompted, then review the consent screen before authorising your assistant.

Terminal clients that support OAuth can use browser sign-in through the guides above. For clients that support bearer headers instead, create a personal access token in Mi cuenta, choose its permissions and send it in the Authorization: Bearer header. See Other MCP clients and terminal for connection details.

What the Assistant Sees, and How to Disconnect

Within the permissions you authorise, your assistant can access the event information you see in your dashboard, including guest contact details, invitation links, wall messages, tables and prepared reminders. When you connect and authorise access, that information can be shared with your assistant provider, such as Anthropic for Claude or OpenAI for ChatGPT. To end access immediately, open Mi cuenta, select Apps conectadas, then Desconectar; changes already made are kept. See Data and permissions for details.

Repository Development

This repository contains documentation and a generated tool catalogue; the hosted connector runs in the invitas application. With Node.js 22 installed, run npm run check to verify that generated catalogue files match their source. Run npm run catalog after editing docs/catalog.source.json to regenerate them. See CONTRIBUTING.md.

The docs/ directory contains the catalogue and client guides, examples/ contains conversations, and scripts/ contains the catalogue generator. Changes to this repository publish documentation through the repository; deploying the hosted connector is handled by the application repository.
