  Does this MCP require an internet connection to federal databases?

  No. It uses internal checksum algorithms and mapping rules to validate numbers without external dependencies.

• 02

  Can I validate multiple CNPJs at the same time?

  Yes. You can use the batch validation capability to process a list of identifiers in one go.

• 03

  What information can the AI extract from a CNPJ?

  The AI can deconstruct the ID into its root, branch, and check digits, and it can also infer the state of registration.

• 04

  Which AI clients can use this MCP?

  Any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code can use this capability.

• 05

  Is this for checking if a company is active?

  This MCP checks the mathematical and structural validity of the number. It does not check the current active status in federal registries.

• 06

  Does this capability require an internet connection to the Brazilian Federal Revenue?

  No. The validate_cnpj_format and other capabilities use a local checksum algorithm (weighted summation) to verify the mathematical validity of the CNPJ without making external API calls to federal databases.

• 07

  Can I validate multiple CNPJs at once?

  Yes, you can use the batch_validate_cnpjs capability to process an array of CNPJ strings in a single operation and receive summary statistics.

• 08

  What information is returned when analyzing a CNPJ?

  By using analyze_cnpj_structure, you will receive the root identifier, branch identifier, check digits, and the inferred Brazilian state (UF) based on regional mapping rules.
