DevKit-Tool 2.0.4

DevKit-Tool 2.0.4

Developer Toolkit & AI Companion — local-first development automation for .NET, Next.js, Node.js, and Python projects, with native Claude Desktop MCP integration.

DevKit consolidates the operational steps a developer runs every day (project scaffolding, architecture design, Git, Docker, Azure deploy, databases, messaging, observability, code generation, file management) into a single local API + UI, and exposes the same capabilities to Claude Desktop over MCP. Install once, then drive it from the browser-based UI or from Claude Desktop in natural language.

One-Command Install

dotnet tool install -g DevKit-Tool
devkit

That's it. On first run, devkit automatically installs the devkit-mcp-server package globally via npm, updates the Claude Desktop config, and completes the setup without overwriting your existing MCP connectors. On every subsequent launch the MCP server is pulled to the latest version and the Claude Desktop config is silently kept in sync.

What's New in 2.0.4

This release rebuilds the install experience from scratch. In earlier versions, users had to manually run npm install -g devkit-mcp-server and then devkit-mcp-server --setup. With 2.0.4, both steps are triggered automatically the first time devkit runs. A ~/.devkit-mcp-installed marker file tracks install state so the heavy work isn't repeated, but every launch still pulls the MCP server to the latest version and silently re-syncs the Claude Desktop config.

The Architecture Designer module in the UI is now fully expanded: drag-and-drop component placement, manifest generation for .NET / Next.js / Node.js / Python projects, Docker Compose output, automatic resolution of port conflicts between Jaeger and OpenTelemetry Collector, and the ability to scaffold mixed-stack designs (e.g. dotnet + nextjs together) into multiple frameworks from a single design.

On the MCP server side, more than 160 tools are active, covering code generation, Git, Docker, Azure, PostgreSQL, MSSQL, Couchbase, Redis, Kafka, RabbitMQ, build/test/publish, multi-step shell pipelines, the Jarwis persistent memory system, and connector orchestration with Playwright, Windows-MCP and Excel-MCP.
