Devutils MCP Server

An MCP server that gives your AI assistant 17 developer utilities - base64, UUID, JWT decode, cron, timestamps, JSON, regex. No API keys, no external services, just npx. Its 17 documented tools cover cron, timestamp, json, base64.

People who work with cron, timestamp and json and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Devutils

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add ofershap-mcp-server-devutils -- npx -y mcp-server-devutils

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ofershap-mcp-server-devutils": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-devutils"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package mcp-server-devutils - unscoped; check the name against the project README before installing

registry namespace io.github.ofershap is GitHub-verified and matches the repo owner

03 · What Devutils can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can generate one or more UUIDs (v4), generate a ULID, validate a cron expression, and get current time in multiple formats.
