goldenmatch
MCP serverDev toolsLets your agent find duplicate records across your data without setup.
Available today. Use it from your connected AI after setup.
Needs your own goldenmatch account. You sign in to it and approve access when you connect.
Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.
Then ask your AI: use goldenmatch
About this server
Find duplicate records in 30 seconds. Zero-config entity resolution, 97.2% F1 out of the box.
Install goldenmatch
The server’s own address, for the clients that take one directly. Or connect ahel onceand every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.
Claude Code
claude mcp add --transport http --scope user goldenmatch 'https://goldenmatch-mcp-production.up.railway.app/mcp/'Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://goldenmatch-mcp-production.up.railway.app/mcp/Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=goldenmatch&config=eyJ1cmwiOiJodHRwczovL2dvbGRlbm1hdGNoLW1jcC1wcm9kdWN0aW9uLnVwLnJhaWx3YXkuYXBwL21jcC8ifQ==Open the link and Cursor adds the server at that address.
ChatGPT
https://goldenmatch-mcp-production.up.railway.app/mcp/In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add goldenmatch --url 'https://goldenmatch-mcp-production.up.railway.app/mcp/'Run it once, then sign in with codex mcp login goldenmatch if the server asks for an account.
From the project's README
As published by benseverndev-oss/goldenmatch in README.md. This repository publishes several servers, so only the opening is shown here.
Your customer data lives in a CRM, a billing system, and three spreadsheets nobody owns. Some records are duplicates. Some are the same company spelled four different ways. Nobody can answer how many customers do we actually have, and every dashboard built on top inherits the doubt.
Splink-beating entity resolution, Arrow-native and Rust-fast with zero tuning, feeding a durable identity layer so messy records from every source become stable golden entities with whole-record, Customer-360 provenance.
Zero-config matching that beats expert-tuned Splink head-to-head on messy customer records, in an Arrow-native, Rust-authoritative engine verified from a laptop CSV to a 250M-row dedupe in 11.2 minutes. The identities it produces live in a transaction-native control plane carrying stable entity_ids, per-field provenance, merge/split, and a tamper-evident audit log, all one call away as a Customer 360. It even owns its primitives: byte-identical, faster-than-rapidfuzz / jellyfish / FAISS Rust kernels, not rented dependencies.
