DevUtils MCP server

This is a small helper that gives your AI assistant a set of everyday developer utilities. You paste in a token, a cron schedule, or a messy chunk of JSON, and the AI works it out for you. It is handy for anyone who deals with technical bits and pieces but does not want to open a separate tool for each one.

What this MCP server does

You ask your AI something like "what does this cron expression mean" or "decode this token". The AI passes your request to this helper program running on your own computer. The helper does the actual work, like converting a timestamp or hashing a string. Then the AI shows you the result right in the chat, in plain words.

What you can do with it

• Decode a JWT token and see its header, payload, and whether it has expired
• Generate one or more UUIDs or a ULID
• Hash a string with md5, sha1, sha256, sha384, or sha512
• Explain a cron expression in plain English and list its next run times
• Convert between Unix timestamps and readable dates
• Pretty-print, shrink, or check a chunk of JSON
• Test a regex pattern against a piece of text

Try asking your AI

• “Decode this JWT token: eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...”
• “What does the cron expression 0 9 * * 1-5 mean?”
• “Generate 5 UUIDs for me”
• “Hash this string with SHA-256: hello world”
• “Format this JSON: {"a":1,"b":2}”

What it gives back to you

You get the answer back in the chat, usually as a short block of text or a small list. For example, a decoded token comes back as a header and payload, a cron question comes back as a plain sentence, and a JSON request comes back as neatly indented text. Nothing is saved anywhere, it just shows up in the conversation.

Who it's for

Anyone who works with tokens, timestamps, cron schedules, or JSON and wants quick answers without opening a separate tool.
