MCP Server
Use Stil MCP as the design-system-aware layer between your AI agent, Figma, and your repository
What Stil MCP does
Stil MCP sits above raw execution tools. It answers design-system questions such as what a node should map to, which variant or binding is valid, whether a change is safe, and what execution bundle should be handed to Figma MCP or repo tools.
Core tools
The main entry points are get_ds_context for spec access, check_change_safety for Gate classification, get_impact_report for blast radius, and Figma execution planning tools when AI needs DS-aware guidance before writing to canvas.
Authentication
The hosted server currently uses project-scoped API key auth. OAuth discovery is intentionally disabled for v1.0 and returns 503 until the browser authorization flow is ready for production.
