DataMerge MCP

Gives Claude access to a massive B2B database covering over 375 million companies worldwide. You can pull legal entity information, map out corporate hierarchies to understand parent-subsidiary relationships, and retrieve contact data for business outreach. Reach for this when you need to enrich CRM data, research potential clients, verify company details, or build lead lists without switching between multiple data providers. The streamable HTTP transport means you can integrate it directly into workflows where Claude needs to validate or supplement company information on the fly.
