CNPJ

mcp-dir/cnpj-mcp

Connects Claude and other MCP clients to Brazil's Federal Revenue public CNPJ registry and the national court diary (DJEN). Two tools: cnpj_consultar pulls company registration data including legal name, status, tax classification, and the full shareholder list (QSA), while cnpj_processos discovers lawsuits by resolving the CNPJ to names and searching the court diary. No authentication required, read-only operations on public data. Useful for due diligence workflows when you need to verify a Brazilian company's registration or find litigation history for both the entity and its partners. Works well alongside DataJud for enriching case numbers with full docket details.
