Short answer

How can I verify Mexican RFC and CURP data using AI?

Your AI uses Nubarium tools to check if RFC and CURP strings match official Mexican formats and records. This process flags invalid entries immediately so you can fix them. You'll see the specific validation results for every record you submit.

Validation outcomes

Where your data lands

What happens after your AI runs the checks.

VALID

Clean data records

The AI confirms the RFC or CURP is legitimate. You get a clear signal that the identity data is ready for use.

INVALID

Error flagging

The AI identifies malformed or non-existent tax and identity numbers. It highlights exactly what failed the check.

HUMAN

Manual review needed

If a record fails validation, the AI hands the discrepancy to you. You decide if the user needs to resubmit or if the data is truly fraudulent.

LOG

Compliance audit trail

Every check is logged through your AI client. You keep a record of which identities were verified and when.

The workflow

What your AI does when data arrives.

The AI takes raw strings and runs them through specific validation tools to ensure they meet Mexican regulatory standards.

  1. Identify data type

    Your agent looks at the input to determine if it's dealing with a tax ID or a personal identity number.

  2. Check tax IDs

    The AI runs the RFC string through the validation tool to confirm it is a valid Mexican tax identifier.

    validate_mex_rfc

  3. Check identity numbers

    The agent verifies the CURP to ensure the personal identity code is correctly formatted and recognized.

  4. Report results

    The AI summarizes the findings, telling you which records passed and which ones need your attention.

FAQ

How this task behaves

  • 01

    Can the AI fix a typo in an RFC automatically?

    No. The AI identifies that the RFC is invalid, but it won't guess the correct characters. You must provide the corrected data.

  • 02

    Does the AI update official government databases?

    No. This MCP only reads and validates data against existing standards. It cannot write to or change official Mexican tax records.

  • 03

    Can I validate multiple RFCs at once?

    Yes. You can provide a list or a file, and the AI will process the validation for each entry.

  • 04

    What happens if a CURP is valid but the person doesn't exist?

    The tool checks if the CURP follows the correct structure and logic. It is a validation of the data format and identity string.

  • 05

    Does the AI store my users' private data?

    No. The AI uses the data to perform the check and then passes the result to you. Vinkius manages the connection, not your sensitive data.
