Your agent, your knowledge: using Nexbid from Claude, ChatGPT or your own agent

Nexbid can be used from Claude, ChatGPT or your own agent: public tools without a key, bookings with an API key. How to set up the connection and why your own knowledge stays with your agent.

What this is about Many teams already work with an AI assistant: the agency with Claude in the browser, the developer with Claude Code in the terminal, the in-house team with its own agent built on internal documents. The question is rarely whether an agent helps, but where it gets its facts from and what it is allowed to do. This article shows how to plug Nexbid into such an agent as a tool.

The MCP server is in production and offers 19 tools. They fall into two groups. Without a key: search and look up Seven tools are public. They only read and change nothing.
