How does the tool decide which contact is the primary record?

The `select_primary_record` tool picks the record with the highest completeness (most non-empty fields). If there is a tie, it selects the record with the alphabetically first ID.

What fields can I use to match contacts?

You can match contacts using email, phone, or a normalized version of their name via the `analyze_contact_duplicates` tool.

Can I check for specific field inconsistencies?

Yes, use `detect_field_conflicts` and provide a list of field names you want to inspect for discrepancies within your merge groups.

This MCP server provides tools to clean and unify contact datasets. Use analyze_contact_duplicates to group identical contacts by email, phone, or normalized name. Once groups are identified, use detect_field_conflicts to find data discrepancies and select_primary_record to deterministically pick the most complete master record for each identity.
