The tools this server listed when we connected to it, in its own words.
what_can_you_do — Describe a task in plain language (any language) and get back exactly which tools on this server do it, with ready-to-run example calls — inredact_text — Strip emails, phone numbers, ID numbers, API keys, private keys, JWTs, card numbers and IPs out of text, returning the redacted text plus a json_yaml — Converts JSON to YAML or YAML to JSON. It works out which one you gave it, so you do not have to say. A parse failure comes back with the pavalidate_json — Checks that text parses as JSON, and optionally that required keys are present with the right top-level types. Returns the specific violatiodiff_text — Returns which lines were added and which were removed, with line numbers — computed with a longest-common-subsequence, not guessed by a modejwt_decode — Decodes the header and payload of a JWT and reports issued-at / expiry as readable timestamps plus seconds remaining. The signature is NOT vregex_test — Runs a regular expression against sample text and returns every match with its position and capture groups (named groups included). Use befotranspile_sql — Convert a SQL statement from one dialect to another — mysql, postgres, sqlite, tsql, oracle, snowflake, bigquery, redshift, spark, hive, premake_qr — Any text or URL → a QR code PNG you can embed or download. Stateless URL form: https://ainetcafe.com/i/qr/<text>json_format — Validate and pretty-print JSON (2-space indent). Reports the error location if invalid.timezone_convert — Convert a time between time zones, or get current time in any zone. from/to = IANA zone (Asia/Shanghai), time = YYYY-MM-DDTHH:mm (default nounit_convert — Convert units: length, weight, temperature, area, volume, speed, data size. value + from + to (e.g. 100 km mi, 25 c f).sql_from_description — Plain-language request + table schema → ready-to-run .sql file with comments.screenshot_url — Full-page screenshot of any URL → PNG. The same job screenshot APIs charge $7-79/month for.Not tested by KitScout yet. When our harness runs it, pros, cons and the tasks we tried appear here, with the date and evidence.
