🧵 (1/3) Most AI-generated code looks good until you try to merge it. Wrong props, odd states, subtle regressions.
Storybook MCP fixes that.
It turns your stories, docs & tests into machine-readable context so agents actually follow your patterns.

Better context > more context. Been running experiments on LLM cost:
- Vanilla prompt $0.71
- With Storybook MCP: $0.39
That’s 45% fewer tokens for the same job.

We cut @chromatic.com total accessibility violations by over 66% in the last 6 weeks. Here's how:
Over the years, we accrued a11y debt because it was everyone and no one's responsibility. Sure, we did VPATs but they were out of date the moment they were finished.

🫧 Cleaner, simpler codebase
⛓️💥 Reduced bugs from module duplication and aliasing
🧱 A more future-proof foundation for Storybook and its ecosystem

A11y lags behind because testing doesn’t match how we build software. Why?
- Audits live outside the dev workflow
- Page-level tests create noise
- CI/CD gets blocked by a ton of old issues

Testing components that depend on things like localStorage or authentication can be tricky. Storybook makes it easy with our new module mocking API built on top of @vitest.dev's excellent mocking tools.
