Tools

• generate-avatar ~232 tokens
  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 ~176 tokens
  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 synthetic, not issued credentials.
• generate-color ~293 tokens
  Generate a palette from a base color and harmony scheme. Use for design prototypes; defaults: random base, triadic scheme, five hex colors. Returns {base, scheme, colors, textOnBase}; text color is heuristic, not a WCAG contrast check.
• generate-dataset ~256 tokens
  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 eight records without accessing a database.
• generate-fake-data ~207 tokens
  Create fictional users, companies, addresses or rows. Use to seed demos with preset records; use generate-dataset for custom fields. Synthetic values are not verified identities.
• generate-hash ~174 tokens
  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 for password storage or key derivation.
• generate-lorem ~190 tokens
  Generate lorem ipsum placeholder copy. Use for mock layouts needing filler words, sentences or paragraphs. Returns synthetic copy, not sourced editorial content.
• generate-password ~196 tokens
  Generate random or seeded test passwords. Use for demo login fields; use generate-token for identifiers. Seeded values are predictable and visible to MCP clients; not a secure credential vault.
• generate-phone-number ~266 tokens
  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 array of fictional (AAA) 555-01XX numbers; no subscriber lookup.
• generate-prompt ~289 tokens
  Fill a prompt template with supplied variables. Use {name} placeholders with matching vars.name; missing variables become empty text. Returns a prompt string without invoking a model; code/image modes can add framing.
• generate-slug ~161 tokens
  Convert a title into a Unicode-aware URL slug. Use when forming new path segments from headings. Inspect output before publishing permanent URLs.
• generate-ssn ~242 tokens
  Generate fictional US SSN-style test identifiers. Use for SSN test fields; use generate-fake-data for mixed-record fixtures. Returns a string for count=1, otherwise an array; structural validity does not confirm issuance.
• generate-token ~214 tokens
  Generate token strings or UUIDs. Use for test identifiers; use generate-password for password fixtures. Seeded output is predictable and unsuitable for authentication credentials.
• is-card-safe ~146 tokens
  Check payment-card brand, length and Luhn checksum. Use with synthetic card numbers in payment-form tests. Returns {ok, normalized?, brand?, last4?, issues}; not a payment authorization or fraud check.
• is-email-safe ~140 tokens
  Check conservative ASCII email address syntax. Use to reject malformed addresses in forms and test fixtures. Returns true or false; does not check mailbox existence or deliverability.
• is-iban-safe ~150 tokens
  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}; does not verify account ownership or transferability.
• is-ip-safe ~129 tokens
  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, 6 or null.
• is-iso-date-safe ~132 tokens
  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, otherwise false.
• is-json-safe ~155 tokens
  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, issues, bytes, depth, keys, value?}; parsed value is included only when valid.
• is-password-safe ~147 tokens
  Evaluate password strength using local heuristics. Use only with dummy passwords when testing password policies. Returns {ok, score, entropyBits, length, sets, reasons, suggestions}; no breach-database lookup.
• is-phone-e164 ~153 tokens
  Check phone number syntax against E.164 after local normalization. Use to test international number formats, including spaces or 00 prefixes. Returns true or false, not the normalized number; no subscriber or reachability check.
• is-url-safe ~131 tokens
  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 ~145 tokens
  Check synthetic US EIN, SSN or ITIN number formats. Use with tax-ID input fixtures, never real personal identifiers. Returns {ok, normalized?, type, issues}; does not verify IRS issuance or identity.
• is-uuid-safe ~174 tokens
  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 uniqueness or resource existence.
• is-vat-safe ~132 tokens
  Check country-specific VAT number patterns. Use to screen VAT fixtures before form submission. Returns {ok, country?, normalized?, issues}; no VIES lookup or active-registration check.
• minify-css ~122 tokens
  Reduce whitespace in CSS snippets. Use for basic stylesheet cleanup rather than production minification. Not a full CSS parser; visually test the result.
• minify-html ~147 tokens
  Remove comments and compact whitespace in HTML fragments. Use for small, controlled HTML snippets, not full document compilation. Returns an HTML string; preserves pre, textarea, script and style contents. Regression-test rendered output.
• minify-js ~137 tokens
  Compact small JavaScript snippets. Use for basic source cleanup, not AST-aware production minification. Returns JavaScript text, sometimes unchanged for complex syntax; regression-test its behavior.
• minify-prompt ~141 tokens
  Normalize prompt whitespace and line breaks. Use to compact formatting before calling a model; filler phrases are not removed. Returns trimmed text with normalized spacing; review prompts where whitespace carries meaning.
• optimize-dataset ~187 tokens
  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; trims strings, deduplicates rows and may drop mostly empty columns.
• optimize-google-tag ~159 tokens
  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 loading and a config call, or original input if no G- ID exists. Review lost settings and consent.
• strip-ansi ~127 tokens
  Strip terminal ANSI escape codes from text. Use to make colorized logs readable for indexing or display. Returns plain text without interpreting log entries.
