Use OpenRegistry from Haystack

Use OpenRegistry as a Haystack tool inside any Pipeline or Agent built with deepset Haystack.

Haystack ships first-class MCP support via the MCPToolset component. Wire any OpenRegistry tool into a Haystack Pipeline, or expose the full set to a Haystack Agent for autonomous KYC / due-diligence workflows.

Install

pip install haystack-ai mcp-haystack
