Dun & Bradstreet brings its Commercial Graph to ChatGPT and Codex

Dun & Bradstreet announced on June 3, 2026 a collaboration with OpenAI that lets users access the D&B Commercial Graph in ChatGPT and Codex through Model Context Protocol servers. The company says the plugins let finance professionals bring verified business identity, ownership, relationship, credit and risk data into their workspace for due diligence, financial reporting, validation, guidance and credit origination. Customers connect D&B-hosted MCP servers to ChatGPT and Codex and work through natural language prompts and custom agents. D&B's Finance Analytics tools are also available through MCP for automated business credit decisions using a rules-based engine.

The details

• The Commercial Graph is anchored by the D-U-N-S Number and combines public and proprietary commercial signals with directly contributed business information.
• D&B says the graph covers business identity, ownership, supplier relationships, financials and risk indicators.
• The company cites more than 100 billion verifications, tests and checks each month.
• Finance Analytics through MCP supports portfolio-level risk management in what D&B calls a headless AI architecture.
• The announcement names enterprises and small and mid-sized businesses as target users, with a quote from Scott Spencer, General Manager, Finance and Credit.
