MCP Tool

An MCP tool is a single action you let an AI assistant run for you.

Think of it as one button the assistant can press: "check availability," "book a demo," "look up pricing." The assistant reads the tool's schema, decides it fits the buyer's request, and calls it during the conversation.

A bundle of these tools, served together, is your MCP server.

Why it matters for the ChatGPT funnel

This is where the lead actually gets booked.

When a buyer asks ChatGPT a commercial question, the assistant doesn't just describe you. If you expose the right tool, it can act, pulling a calendar slot or capturing the lead without the buyer ever leaving the chat.

No tool means the assistant can only talk about you. A good tool means it can close for you. That is the gap between showing up in the answer and showing up in your pipeline.

How drio fits

You don't design tools or write schemas. drio defines the booking and lead-capture tools the assistant needs, tuned so it picks yours at the moment of intent. You just watch the meetings land.
