How to validate identifier formats with your AI

Connect this MCP to your AI client to run instant format checks on any string. It handles the heavy lifting of pattern matching so you don't have to.

Ask AI about this page

Short answer

Can my AI check if a string is a valid UUID or ULID?

Yes. Your AI uses the validate_identifier tool to confirm if a specific string follows the exact structure required for UUIDs or ULIDs. This ensures your data stays clean and consistent.

Where every result lands.

Validation outcomes

The AI processes your input and categorizes the results based on the identifier type.

VALID

Confirmed formats

The AI identifies a perfect match for a UUID or ULID. You get a clear confirmation that the string is safe to use.

INVALID

Format errors

The AI flags strings that fail to meet the required character or length standards. This prevents bad data from entering your system.

UNKNOWN

Unrecognized types

If a string doesn't fit either standard, the AI marks it as an unknown format. This helps you spot outliers that aren't UUIDs or ULIDs.

HUMAN

Manual review needed

When the AI finds a suspicious pattern that doesn't clearly pass or fail, it flags the item for you to inspect manually.

The workflow

What your AI does when a string arrives.

The AI acts as a gatekeeper for your data integrity.

  1. Pattern analysis

    Your AI examines the provided string to determine its length and character composition.

    validate_identifier

  2. Standard matching

    The AI compares the string against the strict rules for UUID and ULID structures.

    validate_identifier

  3. Integrity check

    The tool confirms if the identifier is technically sound and ready for database insertion.

    validate_identifier

  4. Error reporting

    The AI summarizes why a string failed validation so you can fix the source data.

  • Check if this UUID is valid: [insert string]

  • Is this ULID formatted correctly? [insert string]

  • Scan the IDs in this CSV file and tell me which ones are invalid.

  • Validate these three strings against UUID standards: [string 1], [string 2], [string 3]

FAQ

How the validation works

  • 01

    Can the AI fix a broken UUID for me?

    No. The AI only validates the format. If a string is broken, you have to fix the source data yourself.

  • 02

    Does the AI check for duplicate IDs?

    No. This tool only checks if the format is correct. It does not check your database to see if the ID already exists.

  • 03

    What happens if I provide a random string?

    The AI will run the validation and tell you that the string does not match the UUID or ULID format.

  • 04

    Can I use this to validate custom ID formats?

    No. The tool is specifically built for UUID and ULID standards only.

  • 05

    Will the AI change my data?

    No. The AI only reads the strings you provide to perform the check. It cannot modify your files or databases.
