Cpfhub
Let your coding agent query and validate Brazilian CPF records via CPFHub.io while you build signup, billing, or compliance features.
Overview
CPFHub is a MCP server for the Build phase that lets agents query Brazilian CPF data through CPFHub.io using a stdio npm package and API key.
What is this MCP server?
- Stdio MCP package @cpfhub/mcp on npm at version 1.0.1
- Requires CPFHUB_API_KEY secret environment variable
- Purpose-built for Brazilian CPF lookups from AI agents
- Open-source repository cpfhub/cpfhub-mcp on GitHub
- Fits KYC, onboarding, and fraud-check automations in agent-assisted development
- Package version 1.0.1
- 1 stdio npm package: @cpfhub/mcp
- 1 required secret: CPFHUB_API_KEY
What problem does it solve?
Building Brazil-facing apps forces repetitive manual CPF API calls and fixture juggling while your agent codes onboarding or validation logic.
Who is it for?
Solo builders implementing Brazilian customer onboarding, billing identity checks, or back-office tools who want MCP-native access to CPFHub.
Skip if: Products outside Brazil, teams without a CPFHub account, or use cases that need bulk scraping without an approved data vendor.
What do I get? / Deliverables
With CPFHUB_API_KEY configured, your agent can call CPFHub tools during development to verify integration behavior against real API semantics.
- MCP tools wrapping CPFHub CPF query operations
- Faster agent-driven integration tests against Brazilian ID data
- Documented stdio server entry in your MCP config
Recommended MCP Servers
Journey fit
Identity and tax-ID lookups belong in Build when you wire third-party data APIs into your product backend and agent workflows. Integrations is the right shelf because the server is a thin MCP bridge to CPFHub’s HTTP API, not a monitoring or launch tool.
How it compares
Specialized Brazilian identity API MCP, not a general open-data or global KYC marketplace skill.
