66993e9121Implements icon support based on the Model Context Protocol specification, allowing servers to specify display icons with optional size, MIME type, and theme variants. ## Changes - Add `Icon` type to `pkg/model/types.go` with struct tags for automatic API validation - Add `icons` field to `ServerJSON` in `pkg/api/v0/types.go` - Add icon validation in `internal/validators/validators.go`: - Only HTTPS URLs allowed (no HTTP or data URIs) - Maximum URL length of 255 characters - Validates absolute URLs with proper scheme - Update JSON schema and OpenAPI documentation with Icon definitions - Add comprehensive test cases for icon validation - Add example icon to seed.json (Airtable server) - Change `websiteUrl` validation to HTTPS-only for consistency ## Implementation Details The implementation uses a two-layer validation architecture: 1. **Huma framework** validates struct tags (`required`, `maxLength`, `enum`, `pattern`) and returns 422 for violations 2. **Custom validators** handle business logic (HTTPS scheme requirement, absolute URL requirement) and return 400 for violations This approach leverages Huma's automatic validation while keeping business-specific rules in the validator layer. ## Icon Field Specification - `src` (required): HTTPS URL to icon resource, max 255 characters - `mimeType` (optional): One of `image/png`, `image/jpeg`, `image/jpg`, `image/svg+xml`, `image/webp` - `sizes` (optional): Array of size strings in "WxH" format or "any" for scalable formats - `theme` (optional): Either "light" or "dark" to indicate intended background Multiple icons can be provided (e.g., for different themes or sizes).
