The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_text Analyze Text ~60
Exact counts for a text: characters, words, lines, sentences, paragraphs, bytes. Use this rather than estimating — counting long text is a classic model failure. Web version: https://buildutilities.com/word-counter
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | – |
No output schema declared.
No examples provided.
base64_decode Base64 Decode ~62
Decode Base64 (standard or URL-safe) back to text. Reports whether the input was valid rather than returning mojibake. Web version: https://buildutilities.com/base64-codec
| Name | Type | Req | Description |
|---|---|---|---|
| encoded | string | yes | Base64 or base64url input |
No output schema declared.
No examples provided.
base64_encode Base64 Encode ~65
Encode text to Base64. Set urlSafe for the URL/filename-safe alphabet (-_ instead of +/, no padding). Web version: https://buildutilities.com/base64-codec
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | Text to encode |
| urlSafe | boolean | – | – |
No output schema declared.
No examples provided.
check_color_contrast Check Colour Contrast ~99
Compute the exact WCAG 2.2 contrast ratio between two colours and report which AA/AAA thresholds it passes. This is a specific formula, not a judgement call — do not estimate it. Web version: https://buildutilities.com/color-contrast-checker
| Name | Type | Req | Description |
|---|---|---|---|
| background | string | yes | Hex colour, e.g. #ffffff |
| foreground | string | yes | Hex colour, e.g. #1a1a1a |
No output schema declared.
No examples provided.
convert_timestamp Convert Timestamp ~96
Convert between Unix epoch and human-readable time, in any IANA timezone. Auto-detects seconds vs milliseconds. Use this rather than doing the arithmetic in your head. Web version: https://buildutilities.com/timestamp-converter
| Name | Type | Req | Description |
|---|---|---|---|
| timeZone | string | – | IANA timezone, e.g. "America/New_York" |
| value | string | yes | Epoch seconds/ms, an ISO 8601 string, or "now" |
No output schema declared.
No examples provided.
cron_next_runs Cron Next Runs ~127
Parse a standard 5-field cron expression and list its next run times in a timezone. Handles the Vixie rule that day-of-month and day-of-week are OR'd when both are restricted — the case models most often get wrong. Rejects non-standard syntax (L, W, #) rather than guessing. Web version: https://buildutilities.com/cron-expression-generator
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | – |
| expression | string | yes | e.g. "*/15 9-17 * * mon-fri" or "@daily" |
| timeZone | string | – | – |
No output schema declared.
No examples provided.
decode_jwt Decode JWT ~93
Decode a JSON Web Token's header and payload and report expiry. This DECODES ONLY — it does not verify the signature, so never treat the contents as trusted on the strength of this output. Models asked to read a JWT tend to invent its claims; this reads them. Web version: https://buildutilities.com/jwt-decoder
| Name | Type | Req | Description |
|---|---|---|---|
| token | string | yes | The JWT, optionally prefixed with 'Bearer ' |
No output schema declared.
No examples provided.
diff_text Diff Text ~75
Line-by-line diff of two texts, marking - removed and + added. Use it to check exactly what changed between two versions instead of eyeballing them. Web version: https://buildutilities.com/text-diff-checker
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | yes | – |
| before | string | yes | – |
| ignoreWhitespace | boolean | – | – |
No output schema declared.
No examples provided.
escape_regex Escape Regex Literal ~31
Escape a string so it can be used as a literal inside a regular expression.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | – |
No output schema declared.
No examples provided.
format_json Format or Minify JSON ~99
Pretty-print or minify JSON exactly, with precise error location when it is invalid. Prefer this to reformatting a large document yourself — it cannot drop or alter a value. Web version: https://buildutilities.com/json-formatter
| Name | Type | Req | Description |
|---|---|---|---|
| indent | integer | – | – |
| json | string | yes | The JSON text |
| mode | string | – | – |
| sortKeys | boolean | – | Sort object keys — useful for diffing two payloads |
No output schema declared.
No examples provided.
generate_password Generate Password ~126
Generate a cryptographically random password. Guarantees at least one character from every enabled set. Use this rather than inventing a password — model-authored ones are guessable. Web version: https://buildutilities.com/password-generator
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | How many passwords |
| digits | boolean | – | – |
| excludeAmbiguous | boolean | – | Drop characters that look alike: l 1 I O 0 o |
| length | integer | – | Characters in each password |
| lowercase | boolean | – | – |
| symbols | boolean | – | – |
| uppercase | boolean | – | – |
No output schema declared.
No examples provided.
generate_token Generate Random Token ~75
Generate a cryptographically random token — API keys, session ids, nonces, salts. Choose hex, base64url or alphanumeric encoding. Web version: https://buildutilities.com/random-string-generator
| Name | Type | Req | Description |
|---|---|---|---|
| bytes | integer | – | Bytes of entropy before encoding |
| count | integer | – | – |
| encoding | string | – | – |
No output schema declared.
No examples provided.
generate_uuid Generate UUID ~76
Generate cryptographically random UUID v4 identifiers. Use this instead of writing a UUID yourself — model-authored UUIDs are not random and repeat across sessions. Web version: https://buildutilities.com/uuid-generator
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | How many UUIDs to generate |
| uppercase | boolean | – | Return them uppercased |
No output schema declared.
No examples provided.
hash_text Hash Text ~86
Compute a cryptographic digest of text. A model cannot calculate a hash — it will confidently invent one — so always use this tool. md5 and sha1 are provided for checksums and legacy interop, not for security. Web version: https://buildutilities.com/hash-generator
| Name | Type | Req | Description |
|---|---|---|---|
| algorithm | string | – | – |
| encoding | string | – | – |
| text | string | yes | – |
No output schema declared.
No examples provided.
hmac_sign HMAC Sign ~68
Compute an HMAC of a message with a secret key — webhook signatures, API request signing. Web version: https://buildutilities.com/hmac-generator
| Name | Type | Req | Description |
|---|---|---|---|
| algorithm | string | – | – |
| encoding | string | – | – |
| message | string | yes | – |
| secret | string | yes | – |
No output schema declared.
No examples provided.
hmac_verify HMAC Verify ~74
Check a message against an expected HMAC using a constant-time comparison. Use this to validate an inbound webhook signature rather than comparing strings yourself.
| Name | Type | Req | Description |
|---|---|---|---|
| algorithm | string | – | – |
| message | string | yes | – |
| secret | string | yes | – |
| signature | string | yes | The signature to check, hex or base64 |
No output schema declared.

slugify Slugify ~58
Turn text into a URL-safe slug, transliterating accents and collapsing separators. Web version: https://buildutilities.com/slug-generator
| Name | Type | Req | Description |
|---|---|---|---|
| maxLength | integer | – | – |
| separator | string | – | – |
| text | string | yes | – |
No output schema declared.
No examples provided.
test_regex Test Regular Expression ~110
Actually execute a regular expression against text and return every match with its index and capture groups. Use this instead of predicting what a pattern matches — reasoning about a regex is not the same as running it. Web version: https://buildutilities.com/regex-tester
| Name | Type | Req | Description |
|---|---|---|---|
| flags | string | – | Regex flags, e.g. gi, gm, gs |
| maxMatches | integer | – | – |
| pattern | string | yes | The pattern, without delimiters |
| text | string | yes | Text to search |
No output schema declared.

|---|---|---|---|
| mode | string | – | – |
| text | string | yes | – |
No output schema declared.
