Database MCP for Claude to pull targeted lead lists

April 2, 2026Nick Abraham

Nick Abraham describes building an MCP on their database and having Claude extract 7,500 valid emails with targeting guardrails, but the output quality was disappointing despite a well-built connector.

We built an MCP on our database and told Claude to pull 7,500 valid emails from it.
The results were disappointing.
For context, we gave it some guard rails around targeting and which job titles to pull based on company size.
