AI agent identity: D&B rebuilt its 642M-company graph

Dun & Bradstreet rebuilt its Commercial Graph into a cloud-based knowledge graph covering 642 million companies.

It also added an MCP-based access layer so AI agents can query business data with low-latency responses.

A new registration model lets machines be authenticated and matched to verified entities before they act.

The move highlights how enterprise data systems designed for human users often need redesign for reliable AI workflows in credit, procurement, and risk.
