Make your design system readable for coding agents
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.
- Timeline
- 4 weeks
- Investment
- €12–18k
- Package
- Design System MCP
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
- Inventory the components, tokens and rules agents need to know.
- Write machine-readable contracts for the components in scope.
- Ship an MCP server and connect it to the editors and agents the team uses.
- 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
Final scope depends on the number of components, repositories and agent tools included.
