Auto-discover validation rules from data — scan, profile, health-score. No rules to write.
GoldenCheck MCP server exists for a simple reason — assistants are far more useful when they can act on GoldenCheck directly instead of describing what you should do. Auto-discover validation rules from data — scan, profile, health-score. No rules to write.
Data validation that discovers rules from your data so you don't have to write them. Built by Ben Severn.
Once GoldenCheck is connected, these are the calls the assistant has available:
Flags — The Flags tool exposed by this serverSpeed — The Speed tool exposed by this serverTypeScript — // Scan records (edge-safe) const data = new TabularData(records); const { findings, profile } = scanData(data); for (const f of findings) {Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 4 environment variables: ERROR, OPENAI_API_KEY, ANTHROPIC_API_KEY, GOLDENCHECK_LLM_BUDGET. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. GoldenCheck's toolset — Flags, Speed, TypeScript — is a fair guide to whether it matches your workflow. It is maintained by benseverndev-oss; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against GoldenCheck's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
