AgentBrew – Portable toolbelt for your AI agents

The Universal Hub for AI Agents.

AgentBrew is a centralized Model Context Protocol (MCP) multiplexer. It allows you to configure your tools once and use them across all your AI agents (Claude Code, Gemini CLI, Cursor, etc.).

AI 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.

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.

Lazy : 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 exposesGEMINI.md

andCLAUDE.md

files as resources for your agents.

git clone https://github.com/patchen0518/AgentBrew.git
cd AgentBrew

npm install
npm run build

npm link
agentbrew install <github-url>

agentbrew migrate

agentbrew list

agentbrew enable <package-name>
agentbrew disable <package-name>

agentbrew uninstall <package-name>

agentbrew update <package-name>
agentbrew update --all

agentbrew refresh

Point your AI agent to launch agentbrew

as its MCP server.

Gemini CLI:gemini mcp add agentbrew agentbrew

Claude Code:/plugin add agentbrew agentbrew

Cursor: Add a new "command" type MCP server in settings with commandagentbrew

.

For agents that use a configuration file (like Claude Desktop or other MCP clients), add AgentBrew to your config JSON:

File Paths:

Claude Desktop (macOS):~/Library/Application Support/Claude/claude_desktop_config.json

Claude Desktop (Windows):%APPDATA%\Claude\claude_desktop_config.json

Configuration:

{
  "mcpServers": {
    "agentbrew": {
      "command": "agentbrew"
    }
  }
}

AgentBrew uses an mcp-manifest.json

cache 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

convention.
