Claude Workbench

A modern GUI management tool for the Claude Code CLI with a built-in AI Assistant. It provides a visual interface to manage MCP servers, API credential profiles, custom slash-commands, agent skills, and community plugins — all without manually editing JSON or shell config files. The integrated AI Assistant lets you interact with Claude directly inside the app, with support for tool use, file/image uploads, web search, and streaming responses.

Available as a web app (runs in your browser) or a desktop app (native Electron wrapper for Windows and macOS).

Features

AI Assistant

• Built-in conversational AI assistant powered by Claude, accessible from any tab via floating panel

• File & image uploads: Attach images (PNG, JPEG, GIF, WebP), PDFs, and text-based files (Markdown, JSON, YAML, code files) via paperclip button or paste from clipboard
• Web search: Claude can search the web in real time when answering questions about current events or external topics
• Multi-conversation management: Create, switch, rename, and delete conversations with auto-generated titles
• Model selection: Switch between available Claude models on the fly, including via /model-name slash command
