What it does
Regle is a headless, model-based form validation library for Vue 3. The MCP server packages Regle's validation rules, API, and type definitions so Claude and other AI coding assistants can generate accurate form validation code, provide real-time autocomplete for Regle patterns, and retrieve documentation about async validators, custom rules, and type-safe schemas.
Who it's for
Vue 3 developers using AI coding assistants (Claude, Cursor) who want to implement form validation. Particularly useful for teams relying on AI code generation and autocomplete to speed up building validated forms without manual documentation lookups.
Common use cases
- Generate form validation schemas from natural language prompts
- Query Regle API documentation in real-time while coding
- Implement type-safe validation with TypeScript and Regle
- Set up async validators for server-side validation checks
- Configure custom validation rules and error messages
Setup pitfalls
- Requires Node.js/npm; install via
npx @regle/mcp-server - One secret detected in the repository — verify sensitive data is not exposed
- Configuration path differs by editor:
.cursor/mcp.json(Cursor),.mcp.json(other tools) - CI is not currently passing — test compatibility with your Node and Vue 3 versions
