GoldenMatch

Overview

GoldenMatch is an MCP server that identifies duplicate records in seconds using zero-config entity resolution with 97.2% F1 accuracy out of the box. It integrates directly into AI assistants as callable tools, letting Claude, Cursor, VS Code, and other clients invoke deduplication logic on your data in real time.

Run GoldenMatch two ways: connect to the hosted endpoint at https://goldenmatch-mcp-production.up.railway.app/mcp/ without any local setup, or install the Python package locally via uvx goldenmatch. Version v3.13.0 is available now under the MIT license; source code and 130 stars live at benseverndev-oss/goldenmatch on GitHub.

GoldenMatch appears in the Development category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any MCP-compatible client. If you maintain this project, claim your listing to verify ownership and keep information accurate.
