Short answer

How do I fix inconsistent country names and codes in my data?

Your AI uses the REST Countries MCP to look up official ISO names and codes based on the messy strings you provide. It maps your input to valid identifiers, giving you clean, uniform data.

The results.

Where your data lands.

The AI processes your raw input and sorts the results into these categories.

VALIDATED

Official ISO matches

The AI finds the exact ISO name and code for your input. You get clean, standardized strings for your database.

RECONCILED

Code to name mapping

The AI converts alpha-2 or alpha-3 codes into full official names. This fixes mismatches between different data sources.

AMBIGUOUS

Human review needed

If a name is too vague or matches multiple places, the AI flags it. You decide which specific country is correct.

MISSING

Unrecognized entries

When the AI can't find a match, it marks the entry as invalid. This helps you spot typos or fake data.

The workflow

What your AI does when the data arrives.

The AI acts as a bridge between your messy text and the official ISO database.

  1. Identify the country

    The AI takes a raw string from your sheet or file and tries to find a match in the global database.

    search_by_name

  2. Resolve codes

    If you provide ISO codes, the AI pulls the corresponding official country details.

    search_by_codesearch_by_codes

  3. Verify details

    The AI checks the retrieved data against your original input to ensure the mapping is correct.

    search_by_name

  4. Format output

    The AI structures the final ISO names and codes into the format you need for your project.

FAQ

How this task behaves.

  • 01

    Can the AI change my original files directly?

    No. The AI reads your data and provides the corrected values, but you must be the one to save those changes to your files.

  • 02

    What happens if the country name is misspelled?

    The AI uses search tools to find the closest official match. If it can't find a logical match, it will tell you it couldn't find the country.

  • 03

    Does the AI create new country entries?

    No. The AI only retrieves existing data from the official database. It cannot add new or custom countries.

  • 04

    Can I use this to find capital cities?

    Yes. Once the AI finds the country via its name or code, it can access the associated geographic details like capitals.

  • 05

    Will the AI delete any of my data?

    No. This MCP is read-only. It can only look up information and report it back to you.
