- MCP over streamable HTTP (Railway) or local stdio via PyPI `goldenmatch` with `uvx`
- Server version 1.30.0 in catalog manifest

What problem does it solve?
Imported spreadsheets and API dumps hide duplicate contacts and SKUs until they corrupt analytics or billing.
Who is it for?
Solo builders merging leads, users, or catalog rows from CSV exports and shallow integrations without a data team.
Skip if: Teams that need legally audited master-data governance, custom blocking indexes, or petabyte-scale Spark jobs.
What do I get? / Deliverables
Your agent returns duplicate clusters quickly so you can merge or drop rows before they reach production tables.
- Duplicate record groups or match scores your agent can act on
- Faster clean datasets before database import
- Repeatable dedup tool calls from the agent session

How it compares
