Most MCP demos use toy data. For KYB workflows the hard part is registries: 27 jurisdictions all different. OpenRegistry exposes 27 government company registries via one MCP endpoint so an agent can pull filings/UBO data live instead of scraped mirrors.

Many MCP demos stop at toy tools. The harder problem is provenance. If an agent fetches a company profile or officers list, you need the raw registry record plus a source link. Our MCP server queries 27 national company registries live (no mirrors). https://github.com/sophymarine/openregistry
