23 developer utilities — base64, JWT, UUID, hash, QR, regex, timestamps. No API keys.
Connect Devtools to Claude, Cursor or any other MCP client and it stops being a tab you switch to. 23 developer utilities — base64, JWT, UUID, hash, QR, regex, timestamps. No API keys. The devtools mcp server is what makes that connection.
Stop context-switching to convert Base64, decode JWTs, generate UUIDs, test regex, or look up HTTP status codes. mcp-devtools-server puts all these tools directly in your AI assistant.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Fast — Pure local computation, no network calls (except QR)Lightweight — Single dependency (qrcode), ~50KB installedGeneration — The Generation tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at mcp-devtools-server on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Devtools's toolset — Fast, Lightweight, Generation — is a fair guide to whether it matches your workflow. It is maintained by kira-autonoma; worth a glance at recent repository activity before you build anything load-bearing on it.
