Coding agents already write a share of the UI. Without access to the design system they guess: hardcoded colours, duplicate components, props that do not exist. Design System MCP turns the system into contracts and an MCP server agents can query, then measures how well they use it.

## Use it when agents write UI that ignores the system

- Generated code hardcodes values the tokens already define
- Agents recreate components that already exist
- Component docs are written for people, not for tools
- Nobody can say whether agent output follows the system

## What Design System MCP covers

The components, tokens and usage rules your team already has. Each component gets a machine-readable contract. An MCP server exposes the contracts, tokens and guidance to coding agents in your editors and pipelines. An eval benchmark measures how often agents produce on-system UI, before and after.

## Not included

- Rebuilding the component library
- Choosing or licensing the coding agents
- Rolling the setup out across every repository at once

## How Design System MCP runs

1. Inventory the components, tokens and rules agents need to know.
2. Write machine-readable contracts for the components in scope.
3. Ship an MCP server and connect it to the editors and agents the team uses.
4. Benchmark agent output before and after, then hand over.

## What you receive

- Machine-readable contracts for the components in scope
- An MCP server for contracts, tokens and usage guidance
- Drift checks that flag where code and contracts disagree
- An eval benchmark with before and after results
- Documentation for keeping the contracts current

## How the price is set

4 weeks, fixed scope. Final scope depends on the number of components, repositories and agent tools included.

## About Design System MCP

**What is an MCP server?** A Model Context Protocol server lets AI tools look up information on demand. Here it answers questions about your components, tokens and usage rules.

**Which coding agents does it work with?** Any tool that supports the Model Context Protocol. The setup is tested with the editors and agents your team uses.

**Does the design system need to be in good shape first?** It helps. Gaps found while writing the contracts are listed. A UX Sprint/DS Audit can come first when the system needs work.

**How is success measured?** The eval benchmark runs the same UI tasks before and after and compares how often the output follows the system.
