• is-card-safe Check payment-card brand, length and Luhn checksum. Use with synthetic card numbers in payment-form tests. Returns {ok, normalized?, brand?, last4?, issues}; no
• is-email-safe Check conservative ASCII email address syntax. Use to reject malformed addresses in forms and test fixtures. Returns true or false; does not check mailbox exist
• is-iban-safe Check IBAN country rules, length and checksum against a bundled registry. Use to screen public or synthetic IBANs in test data. Returns {ok, normalized?, issues
• is-iso-date-safe Check Gregorian YYYY-MM-DD calendar dates, including leap days. Use for date-only form fields, not timestamps or timezone offsets. Returns true for a valid date
• is-ip-safe Check IPv4 or IPv6 literal-address syntax. Use to screen candidate IP strings, not test reachability or geolocation. Returns {ok, version, issues}; version is 4
• is-json-safe Parse JSON with bounded depth, key counts and input size. Use to screen JSON without execution; use optimize-dataset for JSONL or CSV cleanup. Returns {ok, issu
• is-password-safe Evaluate password strength using local heuristics. Use only with dummy passwords when testing password policies. Returns {ok, score, entropyBits, length, sets,
• is-phone-e164 Check phone number syntax against E.164 after local normalization. Use to test international number formats, including spaces or 00 prefixes. Returns true or fa
• is-uuid-safe Check canonical UUID syntax and optional RFC variant/version. Use to validate UUIDs; use generate-token to create them. Returns true or false; does not check un
• is-url-safe Check absolute HTTP or HTTPS URL syntax. Use to screen links before display or storage. Returns true or false; does not visit or assess the site's safety.
• is-us-tin-safe Check synthetic US EIN, SSN or ITIN number formats. Use with tax-ID input fixtures, never real personal identifiers. Returns {ok, normalized?, type, issues}; do
• is-vat-safe Check country-specific VAT number patterns. Use to screen VAT fixtures before form submission. Returns {ok, country?, normalized?, issues}; no VIES lookup or ac
• optimize-dataset Clean and compact JSON, JSONL or CSV rows. Use for small datasets; use is-json-safe to check JSON syntax without changes. Returns text in the selected format; t
• optimize-google-tag Rebuild GA4 gtag.js markup from a G- measurement ID. Use on existing GA4 snippets, not GTM containers or consent setup. Returns replacement HTML with async load
• minify-html Remove comments and compact whitespace in HTML fragments. Use for small, controlled HTML snippets, not full document compilation. Returns an HTML string; preser
• minify-js Compact small JavaScript snippets. Use for basic source cleanup, not AST-aware production minification. Returns JavaScript text, sometimes unchanged for complex
• minify-css Reduce whitespace in CSS snippets. Use for basic stylesheet cleanup rather than production minification. Not a full CSS parser; visually test the result.
• minify-prompt Normalize prompt whitespace and line breaks. Use to compact formatting before calling a model; filler phrases are not removed. Returns trimmed text with normali
• strip-ansi Strip terminal ANSI escape codes from text. Use to make colorized logs readable for indexing or display. Returns plain text without interpreting log entries.
• generate-avatar Create an SVG placeholder profile icon. Use for synthetic avatars in demos and UI prototypes. Returns SVG markup, not a photorealistic likeness.
• generate-card-number Generate a synthetic payment-card fixture. Use for payment-form UI tests requiring a Luhn-valid card number. Returns {number, brand, expiry, cvc}; values are sy
• generate-color Generate a palette from a base color and harmony scheme. Use for design prototypes; defaults: random base, triadic scheme, five hex colors. Returns {base, schem
• generate-dataset Generate synthetic rows as JSON, JSONL or CSV. Use for data import/export tests; use generate-fake-data for preset people or company fixtures. Returns at most e
• generate-fake-data Create fictional users, companies, addresses or rows. Use to seed demos with preset records; use generate-dataset for custom fields. Synthetic values are not ve
• generate-hash Compute SHA-256 or legacy MD5 text digests. Use for non-secret content fingerprints; generate-token creates new IDs instead. Returns a hex digest; unsuitable fo
• generate-lorem Generate lorem ipsum placeholder copy. Use for mock layouts needing filler words, sentences or paragraphs. Returns synthetic copy, not sourced editorial content
• generate-password Generate random or seeded test passwords. Use for demo login fields; use generate-token for identifiers. Seeded values are predictable and visible to MCP client
• generate-phone-number Generate fictional US-format phone numbers. Use for US demo phone fields; when supplied, city selects a local area-code pool and must match state. Returns an ar
• generate-prompt Fill a prompt template with supplied variables. Use {name} placeholders with matching vars.name; missing variables become empty text. Returns a prompt string wi
• generate-slug Convert a title into a Unicode-aware URL slug. Use when forming new path segments from headings. Inspect output before publishing permanent URLs.
