Coresignal
B2B data and web scraping API for large-scale market intelligence.
EnrichAPI

API & MCP Analysis
For AI-native operators choosing between Coresignal and EnrichAPI, the decision comes down to API accessibility and how easily your agent can interface with each tool.
Coresignal has the edge here with an official MCP server, letting you connect it directly to Claude or Cursor. EnrichAPI requires a REST API integration, which means your agent needs the API docs to build the connection.
"Claude, use Coresignal MCP to find all employees who left [Company] in the last 6 months."
"Claude, use EnrichAPI to research this company URL and generate a personalized outreach angle based on their tech stack and pain points."
