Developer Utilities via MCP
Use this skill for everyday developer utility tasks: encoding, hashing, JWT decoding, cron expressions, timestamps, JSON formatting, and regex testing. Zero auth required.
Available Tools
| Category | Tools |
|---|---|
| Encoding | base64encode, base64decode |
| ID Generation | uuidgenerate, ulidgenerate |
| Hashing | hash (single algo), hash_all (all algos) |
| JWT | jwt_decode (header, payload, expiry check) |
| Cron | cronexplain, cronvalidate, cron_next |
| Timestamps | timestamptoiso, isototimestamp, timestamp_now |
| JSON | jsonformat, jsonminify, json_validate |
| Regex | regex_test |
Key Patterns
jwt_decodeshows header, payload, and checks if expired — does NOT verify signatureshashdefaults to SHA-256;hash_allruns md5, sha1, sha256, sha384, sha512 at oncecron_nextshows the next N scheduled run times — useful for validating cron schedulesuuid_generatecan create multiple UUIDs in one call (passcountparameter)json_validatereports whether input is valid JSON and its root type (object, array, etc.)
