Integration

Goose runs on your machine. Windcraft gives it your design language.

Goose is an open agent built around MCP — it was one of the first public MCP clients, and it extends through MCP servers. Windcraft is one of those extensions: it hands Goose your tokens and contracts so generated UI is on-system, not improvised.

Why an extensible agent still needs design values

Goose can do a lot through its extensions — read files, run commands, hit APIs — but none of that tells it your brand color or spacing scale. Left to its own priors, it reaches for generic values, and across a session of autonomous work those choices accumulate into drift. The extensibility is the answer: add the extension that supplies your design language.

How Windcraft plugs into Goose

Goose loads MCP servers as extensions. Add Windcraft as a stdio extension and Goose can call the design tools — tokens, contracts, patterns — while it works, reading your values instead of guessing.

  1. Run npx windcraft init in your repo to generate the config.
  2. Add Windcraft as a Goose extension (via goose configure or your config.yaml).
  3. Goose calls get_design_tokens / get_component_contract / get_page_pattern as it builds.
  4. Run npx windcraft check to flag any drift before you commit.

Goose extension config (~/.config/goose/config.yaml)

extensions:
  windcraft:
    type: stdio
    cmd: npx
    args: ["windcraft", "mcp"]
    enabled: true

FAQ

Is Windcraft a Goose extension?
Effectively, yes — Goose consumes MCP servers as extensions, and Windcraft runs as one. Add it the way you add any Goose extension and the design tools become available to the agent.
Do I configure it with goose configure?
You can. goose configure walks you through adding a stdio extension, or you can add the block to your config.yaml directly. Either way it runs npx windcraft mcp locally.
Does my source code leave my machine?
No. Goose runs on your machine and so does Windcraft’s server and analyzer. Only metadata — tokens, contracts, rule violations — is synced to the cloud.
