Tools

52 tools
color_contrast
Computes the WCAG 2.1 contrast ratio between two hex colors. Alpha, if present, is composited over white first.
Input schema 
{'type': 'object', 'required': ['colorA', 'colorB'], 'properties': {'colorA': {'type': 'string'}, 'colorB': {'type': 'string'}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['ratio', 'formula'], 'properties': {'ratio': {'type': 'number'}, 'formula': {'type': 'string'}}, 'additionalProperties': False}
color_convert
Converts a color between hex, rgb, hsl, and hsv. value's shape depends on from/to: a string for hex, an object ({r,g,b,a?} etc.) otherwise.
Input schema 
{'type': 'object', 'required': ['from', 'to', 'value'], 'properties': {'to': {'type': 'string', 'description': 'hex, rgb, hsl, or hsv'}, 'from': {'type': 'string', 'description': 'hex, rgb, hsl, or hsv'}, 'value': {'description': 'a hex string, or an {r,g,b,a?}/{h,s,l,a?}/{h,s,v,a?} object per from'}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['value'], 'properties': {'value': True}, 'additionalProperties': False}
csv_from_json
Converts JSON records to CSV text. columns is the explicit, ordered header — JSON object key order can't be relied on to infer it.
Input schema 
{'type': 'object', 'required': ['columns', 'records'], 'properties': {'columns': {'type': ['null', 'array'], 'items': {'type': 'string'}}, 'records': {'type': ['null', 'array'], 'items': {'type': 'object', 'additionalProperties': {'type': 'string'}}}, 'delimiter': {'type': 'string'}}, 'additionalProperties': False}
Output schema 
{'type': 'string'}
csv_parse
Parses CSV text into rows of string fields (no type guessing). Ragged rows are tolerated — use csv_validate to detect them.
Input schema 
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string'}, 'delimiter': {'type': 'string', 'description': "a single character, default ','"}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['rows'], 'properties': {'rows': {'type': ['null', 'array'], 'items': {'type': ['null', 'array'], 'items': {'type': 'string'}}}}, 'additionalProperties': False}

Input schema 
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string'}, 'delimiter': {'type': 'string'}}, 'additionalProperties': False}

{'type': 'object', 'required': ['rowCount', 'columnCount', 'columns'], 'properties': {'columns': {'type': ['null', 'array'], 'items': {'type': 'object', 'required': ['name', 'nonEmpty', 'empty'], 'properties': {'name': {'type': 'string'}, 'empty': {'type': 'integer'}, 'nonEmpty': {'type': 'integer'}}, 'additionalProperties': False}}, 'rowCount': {'type': 'integer'}, 'columnCount': {'type': 'integer'}}, 'additionalProperties': False}
csv_to_json

Input schema 
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string'}, 'header': {'type': 'boolean', 'description': 'default true'}, 'delimiter': {'type': 'string'}}, 'additionalProperties': False}

Input schema 
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string'}, 'delimiter': {'type': 'string'}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['valid'], 'properties': {'error': {'type': 'string'}, 'valid': {'type': 'boolean'}, 'rowCount': {'type': 'integer'}, 'fieldCount': {'type': 'integer'}}, 'additionalProperties': False}
datemath_add
Adds years/months/days to date. years/months are applied together with end-of-month clamping — e.g. 2026-01-31 + 1 month = 2026-02-28, not an overflowed 2026-03-03. days is then applied as plain calendar-day arithmetic.
Input schema

Output schema 
{'type': 'string'}
hash_hmac
Computes an HMAC of input (decoded per encoding) using algo: md5, sha1, sha256, or sha512 (crc32 isn't offered — it's a checksum, not a cryptographic primitive HMAC composes with). key is used as its raw UTF-8 bytes, not decoded per encoding. Returns the MAC as lowercase hex.

Input schema 
{'type': 'object', 'required': ['value'], 'properties': {'value': {'type': 'string', 'description': 'digits-only identifier to validate (no spaces or dashes)'}}, 'additionalProperties': False}

Output schema 
{'type': 'string'}
units_convert_temperature
Converts a temperature value (decimal string) between C, F, and K. Offset-aware, not a bare multiplier.
Input schema 
{'type': 'object', 'required': ['value', 'from', 'to'], 'properties': {'to': {'type': 'string', 'description': 'C, F, or K'}, 'from': {'type': 'string', 'description': 'C, F, or K'}, 'value': {'type': 'string', 'description': 'decimal string'}}, 'additionalProperties': False}
Output schema 
{'type': 'string'}
url_validate
Checks value is a well-formed absolute URL (has both a scheme and a host) — syntax only, not a reachability check.
Input schema 
{'type': 'object', 'required': ['value'], 'properties': {'value': {'type': 'string', 'description': 'identifier or value to check'}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['valid'], 'properties': {'valid': {'type': 'boolean'}, 'reason': {'type': 'string'}}, 'additionalProperties': False}
uuid_generate
Generates count (default 1, max 1000) random version-4 UUIDs from crypto/rand-backed entropy.
Input schema 
{'type': 'object', 'properties': {'count': {'type': 'integer', 'description': 'default 1, max 1000'}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['values'], 'properties': {'values': {'type': ['null', 'array'], 'items': {'type': 'string'}}}, 'additionalProperties': False}
uuid_validate
Parses value as a UUID and reports its version/variant if well-formed.
Input schema 
{'type': 'object', 'required': ['value'], 'properties': {'value': {'type': 'string', 'description': 'digits-only identifier to validate (no spaces or dashes)'}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['value', 'valid'], 'properties': {'valid': {'type': 'boolean'}, 'value': {'type': 'string'}, 'variant': {'type': 'string'}, 'version': {'type': 'integer'}}, 'additionalProperties': False}
vateu_validate
Format validation only (no VIES lookup) for an EU VAT number: checks the 2-letter member-state prefix (EL for Greece, XI for Northern Ireland) against that country's digit/letter pattern. A format-valid result does not mean the number is actually registered.
Input schema 
{'type': 'object', 'required': ['value'], 'properties': {'value': {'type': 'string', 'description': 'identifier or value to check'}}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'required': ['valid'], 'properties': {'valid': {'type': 'boolean'}, 'reason': {'type': 'string'}}, 'additionalProperties': False}
