What is the Snowfakery MCP server?

MCP server for authoring, analyzing, debugging, and running Snowfakery recipes. Exposed over MCP by the snowfakery mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

Snowfakery is a YAML-based tool for programmatically generating test data. This MCP server connects Snowfakery to AI assistants, letting you:

  • Snowfakery documentation and recipe examples
  • JSON schema for recipe validation
  • Run outputs and artifacts
  • Validate & analyze recipes (catch errors early)
  • Run recipes and capture output
  • List & retrieve example recipes

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

When to reach for it

This sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by composable-delivery; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the snowfakery mcp server does with a few real requests.

Configuration as documented by the project. Restart the client after saving.

Frequently asked questions

It connects Snowfakery to MCP-compatible AI assistants such as Claude and Cursor. Instead of copying data back and forth by hand, the assistant works with Snowfakery directly.
