Tools (6)
| Name | Description | Schema |
|---|---|---|
convert_color | Converts a color into code for 12 formats: HEX, HEX8, rgba(), hsla(), closest CSS named color, closest Tailwind class, SwiftUI Color, UIColor, Jetpack Compose, Android XML, Flutter, and React Native. | typed |
check_contrast | Computes the exact WCAG 2.1 contrast ratio between a foreground and background color (relative-luminance formula) and reports AA/AAA pass-fail for normal text (4.5 / 7), large text (3 / 4.5), and UI c | typed |
swiftui_color | Generates every SwiftUI Color initializer for a color: Color(red:green:blue:), opacity variant, Color(.sRGB), Color(.displayP3), HSB, hex-extension call, #colorLiteral, UIColor/NSColor bridges — plus | typed |
generate_uuid | Generates cryptographically random UUIDs: v4 (random), v7 (RFC 9562 time-ordered; batches stay strictly ordered), or NIL. Supports uppercase, hyphen-less, and braced formatting. 1–100 per call. | typed |
hash_text | Computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests of a UTF-8 string, or HMAC variants when a key is given (HMAC-MD5 unsupported). Stateless; input is not stored. | typed |
convert_timestamp | Converts between Unix epoch timestamps and human-readable dates. Accepts epoch seconds / milliseconds / microseconds (auto-detected by magnitude), ISO 8601 / RFC 2822 strings, or "now". Returns second | typed |
