Real-time B2B data API for people and company enrichment with native MCP.
API & MCP Analysis
For AI-native operators choosing between Clearbit (Breeze) and Crustdata, the decision comes down to API accessibility and how easily your agent can interface with each tool.
Crustdata has the edge here with an official MCP server, letting you connect it directly to Claude or Cursor. Clearbit (Breeze) requires a REST API integration, which means your agent needs the API docs to build the connection.
"Claude, use Clearbit API to enrich this list of domains with their employee count and industry."
"Claude, use Crustdata to find 20 Series A SaaS companies in Austin with headcount growth over 20% and enrich their CEO's contact info."
