Grounding an agent on a knowledge graph
Vector search finds similar text; a graph encodes relationships. Agents that reason about your business need both, and this is how you wire them up.
An agent that only does similarity search can answer “what does our refund policy say?” but not “which customers are exposed to the delayed supplier?” The second is a relationship question — it needs a graph.
Grounding an agent on a knowledge graph gives it structured context: entities, their attributes, and the edges between them. The agent can traverse from a supplier to affected products to the customers who ordered them, and cite every hop. Expose that graph as a tool over the Model Context Protocol and any compliant agent can use it under your access controls.
The result is an agent whose answers are explainable and auditable — because they are grounded in governed relationships, not statistical guesses.
