dun-and-bradstreet-mcp.yml

Dun & Bradstreet ships production Model Context Protocol servers as part of the D&B.AI suite. Two distinct servers were confirmed. The D&B Risk Analytics server is a remote, OAuth-protected Streamable HTTP endpoint on a D&B-owned host and was probed live. The D&B Commercial Graph / Direct+ MCP server is distributed through enterprise marketplaces (Microsoft Power Platform, IBM watsonx Orchestrate, Databricks, Amazon QuickSight, Snowflake Cortex) and authenticates with a single Direct+ API key; D&B does not publish its endpoint URL on the open web — access is granted through a "Get Access" request form. A probe of the Direct+ gateway found /v1/mcp answering 401 while a control path (/v1/zzzznotreal) answers 404, which establishes that /v1/mcp is a real, auth-gated route rather than a guess.
