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	`base64_encode` , `base64_decode`
ID Generation	`uuid_generate` , `ulid_generate`
Hashing	`hash` (single algo), `hash_all` (all algos)
JWT	`jwt_decode` (header, payload, expiry check)
Cron	`cron_explain` , `cron_validate` , `cron_next`
Timestamps	`timestamp_to_iso` , `iso_to_timestamp` , `timestamp_now`
JSON	`json_format` , `json_minify` , `json_validate`
Regex	`regex_test`

Key Patterns

```
jwt_decode
```
shows header, payload, and checks if expired — does NOT verify signatures
```
hash
```
defaults to SHA-256;
```
hash_all
```
runs md5, sha1, sha256, sha384, sha512 at once
```
cron_next
```
shows the next N scheduled run times — useful for validating cron schedules
```
uuid_generate
```
can create multiple UUIDs in one call (pass
```
count
```
parameter)
```
json_validate
```
reports whether input is valid JSON and its root type (object, array, etc.)
