It allows you to configure your tools once and use them across all your AI agents (Claude Code, Gemini CLI, Cursor, etc.).\n\nAI developers today face a fragmentation problem: every agent (Claude Code, Gemini CLI, Cursor, etc.) has its own way of managing MCP servers, tools, and skills. Setting up your favorite tools in one agent doesn't mean you have them in another.\n\n**AgentBrew** solves this by acting as a **Universal \"USB Hub\"** for MCP. You install your tools once in AgentBrew, and all your agents can instantly access that same consistent set of capabilities. If you switch agents, your entire \"brew\" of tools and skills comes with you.\n\n**Lazy Loading:** Servers only start when a tool is actually called.**Auto-Discovery:** Automatically detects MCP servers in Node.js, Python, and Markdown projects.**Universal Migration:** Import your existing configurations from Gemini, Claude Code, and Cursor.**Instruction Index:** Automatically exposes`GEMINI.md`\n\nand`CLAUDE.md`\n\nfiles as resources for your agents.\n\n```\n# Clone and enter the repo\ngit clone https://github.com/patchen0518/AgentBrew.git\ncd AgentBrew\n\n# Install and build\nnpm install\nnpm run build\n\n# Link globally\nnpm link\n# Install a tool from a Git URL\nagentbrew install <github-url>\n\n# Migrate from Gemini, Claude, or Cursor\nagentbrew migrate\n\n# Manually link a local command\n# (Internal use or custom scripts)\n# List all tools, prompts, and resources\nagentbrew list\n\n# Enable/Disable a package\nagentbrew enable <package-name>\nagentbrew disable <package-name>\n\n# Uninstall a package\nagentbrew uninstall <package-name>\n\n# Update a specific package or all packages\nagentbrew update <package-name>\nagentbrew update --all\n\n# Refresh capability cache (required after manual file changes)\nagentbrew refresh\n```\n\nPoint your AI agent to launch `agentbrew`\n\nas its MCP server.\n\n**Gemini CLI:**`gemini mcp add agentbrew agentbrew`\n\n**Claude Code:**`/plugin add agentbrew agentbrew`\n\n**Cursor:** Add a new \"command\" type MCP server in settings with command`agentbrew`\n\n.\n\nFor agents that use a configuration file (like **Claude Desktop** or other MCP clients), add AgentBrew to your config JSON:\n\n**File Paths:**\n\n**Claude Desktop (macOS):**`~/Library/Application Support/Claude/claude_desktop_config.json`\n\n**Claude Desktop (Windows):**`%APPDATA%\\Claude\\claude_desktop_config.json`\n\n**Configuration:**\n\n```\n{\n  \"mcpServers\": {\n    \"agentbrew\": {\n      \"command\": \"agentbrew\"\n    }\n  }\n}\n```\n\nAgentBrew uses an `mcp-manifest.json`\n\ncache in each package directory to enable instant startup. The **Router** acts as a dynamic proxy, spawning child MCP processes on-demand and routing requests using a `prefix__name`\n\nconvention.\n\nMIT", "url": "https://wpnews.pro/news/agentbrew-portable-toolbelt-for-your-ai-agents", "canonical_source": "https://github.com/patchen0518/AgentBrew", "published_at": "2026-05-26 04:27:10+00:00", "updated_at": "2026-05-26 04:37:30.328471+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "ai-infrastructure", "ai-products", "artificial-intelligence"], "entities": ["AgentBrew", "Model Context Protocol", "Claude Code", "Gemini CLI", "Cursor", "Node.js", "Python", "Markdown"], "alternates": {"html": "https://wpnews.pro/news/agentbrew-portable-toolbelt-for-your-ai-agents", "markdown": "https://wpnews.pro/news/agentbrew-portable-toolbelt-for-your-ai-agents.md", "text": "https://wpnews.pro/news/agentbrew-portable-toolbelt-for-your-ai-agents.txt", "jsonld": "https://wpnews.pro/news/agentbrew-portable-toolbelt-for-your-ai-agents.jsonld"}}
