Devtools
Let your agent encode, decode, hash, generate IDs, and debug JWTs without leaving the chat or opening extra web tools.
Overview
Devtools MCP is a MCP server for the build phase that provides 23 local developer utilities such as base64, JWT, UUID, hash, QR, regex, and timestamps with no API keys.
What is this MCP server?
- 23 developer utility tools including base64, JWT, UUID, hash, QR, regex, and timestamps
- No API keys or external SaaS required to run the stdio server
- npm package mcp-devtools-server version 1.0.1
- Suited for quick transforms and validations while coding auth, IDs, and payloads
- Package version 1.0.1
- npm identifier mcp-devtools-server
What problem does it solve?
Agents burn context re-deriving encodings, token formats, and IDs instead of calling reliable one-shot dev utilities.
Who is it for?
Indie developers who want fast, offline-friendly helper tools in Claude Code or Cursor while building APIs and agents.
Skip if: Production secret management, enterprise PKI, or teams that forbid local crypto tooling in regulated environments without review.
What do I get? / Deliverables
After install, your agent can run standard encode/decode and formatting operations through MCP tools without external accounts.
- 23 callable MCP dev utility tools
- Offline-capable encode/decode and formatting helpers for agent sessions
Recommended MCP Servers
Journey fit
Daily encoding and crypto chores happen while implementing features and debugging APIs during the build phase. A bundled dev-utility MCP server is classic agent-tooling: small deterministic tools the model calls instead of guessing formats.
How it compares
Local dev-utility MCP toolbox, not a cloud observability platform or security audit service.
Common Questions / FAQ
Who is Devtools MCP for?
It is for builders who want twenty-three common dev transforms available as MCP tools during everyday coding and debugging.
When should I use Devtools MCP?
Use it during build when you need base64, JWT, UUID, hash, QR, regex, or timestamp operations without switching to separate websites or scripts.
How do I add Devtools MCP to my agent?
Install mcp-devtools-server from npm as a stdio MCP server, add it to your host MCP config, and restart the agent—no API keys are required.
