Why Velkin ships a live MCP server for UI agents

AI coding agents are already writing a large share of product UI. When the library is copy-paste source or a headless primitive set with no live schema, the agent invents props, misses slots, and ships markup that fails accessibility checks.

Velkin exposes a public MCP endpoint at https://mcp.velkinui.com/mcp so tools like Cursor and Claude can read real component docs, slot names, and theme tokens before they generate code. The endpoint is rate-limited and read-only — schemas and documentation only, not customer data.

That is the product claim in one line: accessible Lit components with typed React and Vue wrappers, plus an agent-facing contract so humans and AI share the same source of truth.
