AI agents use a context graph to find connected, sourced company facts before they act, so each step rests on who owns what, what changed and why it changed.
An AI agent plans and carries out multi-step tasks: it updates records, sends messages and opens tickets. Each step depends on facts about the company. A context graph gives the agent those facts as connected nodes with sources, so it can check before it acts.
This article is about how agents use a graph. For what a context graph is and how it differs from a knowledge graph, read What Is a Context Graph?
Vector search finds text that looks like the question. That works for a single answer from a single document. Agents often need multi-hop facts: the owner of the account behind this ticket, or the decision that replaced last quarter's plan. A graph answers these by following links, and it returns facts with their sources, so the agent's output can be traced.
An agent should see only what the person it works for may see. A context graph that keeps each source's permissions enforces this on every query. Sources and dates on each fact also let a reviewer check why the agent acted. This is a direct way of reducing AI hallucinations.
