GCNA in your AI assistant

GCNA · 2026-11-12 · Deutsch

Add GCNA's MCP server to your AI assistant, and it can answer questions about Phone System for Nextcloud and Odoo, powered by Vodia, from GCNA's own data: what the apps do, what the Vodia PBX adds next to Nextcloud Talk, current plans and prices, and how to buy.

The server

• Server URL: https://gcn-alliance.com/mcp (Streamable HTTP). No sign-in.
• Four read-only tools: find the integration for Nextcloud or Odoo, list plans, plan a purchase for a team size, and get the link to create a GCNA account.
• It never asks for passwords or payment details. You buy inside the Nextcloud or Odoo app: confirm your e-mail with a code, then pay on Stripe's page.
• It keeps no logs of your requests. Privacy notice.
