Tool changes

2026-10-19is-prompt-minifyremoved
Compress prompt whitespace and filler; semantic equivalence not guaranteed. Use to shorten prompt text before passing it to a model when token budget matters. Do not assume the rewritten prompt preserves all nuances. Transformation tool, not a boolean validator. Returns compacted prompt text that may change phrasing or meaning; compare results on representative tasks.
2026-10-19is-dataset-minifyremoved
Clean or minify JSON/JSONL/CSV data, max 4096 input characters. Use to compact small JSON, JSONL or CSV samples without discarding meaningful fields. For ordinary JSON validity checks, use is-json-safe. Transformation tool, not a boolean validator. Returns an optimized dataset representation; may normalize formatting, so inspect output before production use.
2026-10-19is-strip-ansiremoved
Strip ANSI escape sequences. Use when turning colorized terminal logs into clean text for indexing or display. For structured datasets, use is-dataset-minify instead. Transformation tool, not a boolean validator. Returns text with ANSI escape formatting removed; does not parse log entries.
2026-10-19is-minify-cssremoved
Conservative CSS minification, review results before production. Use for small CSS snippets where basic whitespace cleanup suffices. For JavaScript use is-minify-js; for complex stylesheets use a CSS-aware build tool. Transformation tool, not a boolean validator. Returns compacted CSS source text; not a full CSS parser, so visually regression-test output.
2026-10-19is-minify-jsremoved
Conservative JS minification. Not a parser. Regression-test minified code. Use for small JavaScript snippets where basic whitespace cleanup suffices. For CSS use is-minify-css; for safe production bundling use a real JavaScript parser/minifier. Transformation tool, not a boolean validator. Returns compacted JavaScript source text; not AST-aware, so regression-test behavior before deployment.
2026-10-19is-html-minifyremoved
Conservative HTML minification, review results before production. Use to reduce whitespace in a controlled HTML fragment before delivery. For CSS or JavaScript, use is-minify-css or is-minify-js. Transformation tool, not a boolean validator. Returns minified HTML text using a heuristic, not a standards-compliant HTML parser; regression-test output.
2026-10-19is-google-tagremoved
Rewrite existing Google Analytics tag snippet; review output before production. Use when transforming an already supplied Google Analytics tag snippet. It does not configure GA4 accounts, install tracking or verify consent. Transformation tool, not a boolean validator. Returns a rewritten Google Analytics snippet; check consent behavior and analytics tracking before deployment.
2026-10-19generate-tokenchangeddescriptionmeaning changed
before
Generate tokens/UUIDs with WebCrypto; never use deterministic seed for real secrets. Use for temporary development fixtures or unseeded random UUIDs. Do not use seeded output as authentication credentials; for file digests use generate-hash. Returns a generated value visible to the MCP client; no token is registered with any service.
after · 24% of words in common
Generate token strings or UUIDs. Use for test identifiers; use generate-password for password fixtures. Seeded output is predictable and unsuitable for authentication credentials.
2026-10-19generate-ssnchangeddescriptionmeaning changed
before
Generate synthetic US SSN-style fixtures only, up to 8. Use only to test formatting and field validation in demos. Never use a generated value as anyone's actual Social Security number. Returns synthetic identifiers and does not query Social Security records.
after · 23% of words in common
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.
2026-10-19generate-slugchangeddescriptionmeaning changed
before
Produce Unicode-aware slug from a title. Use when creating an SEO-friendly path segment from a title. To check an existing full URL, use is-url-safe instead. Transliterates/normalizes text locally; verify preferred slugs before publishing permanent URLs.
after · 33% of words in common
Convert a title into a Unicode-aware URL slug. Use when forming new path segments from headings. Inspect output before publishing permanent URLs.

Tools (32)

`generate-avatar`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	Generate lorem ipsum placeholder copy. Use for mock layouts needing filler words, sentences or paragraphs. Returns synthetic copy, not sourced editorial content.
`generate-password`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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.

`is-card-safe`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	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`read-only	Strip terminal ANSI escape codes from text. Use to make colorized logs readable for indexing or display. Returns plain text without interpreting log entries.
