Brazilian Dev Mcp
Validate and generate Brazil-specific identifiers and fixtures (CPF, CNPJ, CEP, phone, currency) while building apps for the Brazilian market.
Overview
Brazilian Dev MCP is an MCP server for the Build phase that gives agents Brazil-specific validation, formatting, and fake data utilities for CPF, CNPJ, CEP, and related fields.
What is this MCP server?
- Brazil-focused dev utilities: CPF, CNPJ, CEP, phone, and currency helpers
- Fake data generation for local testing without leaking real PII
- npm stdio package brazilian-dev-mcp (version 1.1.0)
- stdio transport for Claude Code and Cursor MCP workflows
- Reduces bespoke regex and validator code for common BR formats
- Catalog server version 1.1.0
- npm package brazilian-dev-mcp version 1.1.0 (stdio only)
What problem does it solve?
Shipping for Brazil means reimplementing CPF, CNPJ, CEP, and phone rules repeatedly while agents lack structured tools to generate safe test fixtures.
Who is it for?
Indie builders and small teams targeting the Brazilian market who want MCP-native helpers during backend and form development.
Skip if: Products outside Brazil or teams that need certified identity verification and regulated KYC without their own compliance stack.
What do I get? / Deliverables
After registration, your agent can generate and validate Brazilian identifiers and local test data through MCP instead of scattered snippets in chat.
- Locally running Brazilian Dev MCP via stdio
- Agent-accessible tools for BR identifiers, addresses, phones, and currency
- Consistent test fixtures for Brazilian user and company records
Recommended MCP Servers
Journey fit
Brazil-facing products need correct local formats during build when forms, APIs, and test data are implemented—not as an afterthought at launch. Backend and integration work is where CPF/CNPJ checks, address lookup patterns, and realistic fake data belong in the solo-builder workflow.
How it compares
Locale-specific developer MCP utilities, not a government data API or a general testing framework skill.
