Bernuncia for AI agents
Bernuncia protects the digital addresses of brands, projects and businesses. Your agent talks to it through an MCP server tied to your Bernuncia account: it checks a name on the domains and on the networks and looks after your brands: it saves them, renames them, records which addresses are yours, flags the ones you want and keeps watch. The result shows up in the Bernuncia panel, inside the conversation.

ChatGPT
In Settings, Apps and connectors, turn on developer mode in the advanced settings and create a connector with the URL https://mcp.bernuncia.com and OAuth authentication.
Sign in with your account
When you add the connector, Claude and ChatGPT open Bernuncia's connection page (OAuth 2.1 with PKCE): you sign in with your Bernuncia account, approve the access and return to the conversation.

- "Put the name Zunido on Bernuncia's waiting list with my e-mail."
