Everyday DevTools MCP

17 tiny tools your AI assistant wishes it had — Base64, JSON, JWT, UUID, hashing, cron, regex, passwords, timestamps and more. One MCP server. Zero dependencies. No API keys. Works offline.

Works with Claude Code, Cursor, VS Code, Windsurf and any MCP client.

Install

pip install everyday-devtools-mcp

Related MCP server: mcp-devutils

Connect it

Claude Code

claude mcp add devtools -- everyday-devtools-mcp

Cursor / VS Code / Windsurf — add to your MCP config (mcp.json / settings):

{
  "mcpServers": {
    "devtools": {
      "command": "everyday-devtools-mcp"
    }
  }
}

Then just ask your assistant things like:

  • "Decode this JWT and tell me when it expires"

  • "What are the next 5 runs of cron 0 9 * * 1?"

  • "Hash this string with SHA-256"

  • "Make me a 24-character password"

Tools

Tool

What it does

base64_encode / base64_decode

Text ⇄ Base64

url_encode / url_decode

Percent-encode / decode URLs

uuid_generate

Random UUID v4 (1–100 at once)

hash_text

MD5 / SHA-1 / SHA-256 / SHA-512

json_format / json_minify

Validate + pretty-print or minify JSON

jwt_decode

Read a JWT header/payload, flag expiry (no signature check)

timestamp_convert

Unix ⇄ human date, seconds or milliseconds

cron_next

Next run times for any 5-field cron expression

regex_test

Test a pattern, list all matches

password_generate

Cryptographically secure strong passwords

slugify

Text → URL slug

case_convert

upper / lower / Title / snake / kebab / camel

color_convert

Hex ⇄ RGB

text_stats

Characters, words, lines, sentences

Why another dev-tools server?

  • Nothing to install besides the package itself — pure Python standard library, no Docker, no Node, no network calls.

  • Fast to start, safe to run — everything happens locally on your machine.

  • Honest scope — small sharp tools, each covered by an end-to-end test that speaks the real MCP protocol to the server.

Development

git clone https://github.com/Deependra12349/everyday-devtools-mcp
cd everyday-devtools-mcp
python tests/test_mcp.py   # spawns the server, runs protocol checks

    TDQS

    B3.2/5.0

    Scored across 17 tools

    Disambiguation4/5

    Most tools have clearly distinct purposes, and encode/decode pairs are unambiguous. Minor overlap exists between json_format and json_minify (both validate JSON) and between slugify and case_convert (both transform text case), but descriptions make the boundaries clear enough.

    Naming Consistency4/5

    Nearly all tools follow a consistent snake_case noun_verb pattern (base64_encode, json_format, password_generate, timestamp_convert). The lone outlier is slugify, a bare verb with no noun, but the convention is otherwise predictable.

    Tool Count4/5

    17 tools is slightly heavy for a general dev-utility grab bag, but each tool covers a distinct everyday operation and none feels redundant. The set is reasonably scoped despite brushing the upper end of a comfortable count.

    Completeness4/5

    Encode/decode pairs for base64 and URL are symmetric, and hashing, JSON, UUID, and password tooling cover common needs. Gaps like JSON escaping, base/number conversion, or date formatting are minor and easily worked around.
