About This Launch
CPFHub.io is a REST API for Brazilian CPF data with a remote MCP server so AI agents can call it as a tool (https://api.cpfhub.io/mcp). Simple lookup returns name, gender and birth date in about 150 ms, and real-time lookup (CPF plus birth date) checks registration status and death year directly at Receita Federal in about one second. Bulk jobs handle up to 10,000 CPFs. Free plan with 50 credits per month, no card required.
Why I Built This
Brazilian companies need to check CPF data during onboarding, but most options were slow, expensive or hard to integrate. We built a simple, fast API with a free plan, and added an MCP server so AI agents can use it directly.
