Build the Graph in the Background

In this challenge, you make the agent build a knowledge graphA representation of real-world entities and their relationships, stored according to organizing principles, typically in a graph database. from what your MCP tools return, without making you wait for it.

The built-in tools already have a mapper, a plain function that turns an email into Email and Person nodesA vertex in a graph. In a property graph it can carry labels and properties.. You cannot write one for every tool you connect, and you do not know the shape of what an MCP server returns. For these tools, a model reads the output and extracts the entities, using the ontology you defined in the last lesson.
