CPFHub.io

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; tools lookup_cpf, lookup_cpf_realtime and get_quota_info). Simple lookup (GET /cpf/{cpf}) returns name, gender and birth date in about 150 ms. Real-time lookup (POST /cpf/realtime, 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, with public OpenAPI docs. Free plan: 50 credits per month, no card required; paid plans start at about US$4 per month.
