🚀 Installation

run directly with `npx` (recommended):

npx @team-attention/mcproxy

Or install globally:

npm install -g @team-attention/mcproxy

🛠 Usage

Basic Usage

Wrap your MCP server command with `mcproxy`:

mcproxy npx -y @modelcontextprotocol/server-filesystem /path/to/dir

With Claude Code (.mcp.json)

Configure your `.mcp.json` to use `mcproxy` as a wrapper. This allows you to control which tools are exposed to Claude.

  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y", "@team-attention/mcproxy",
        "--",
        "npx", "-y", "@modelcontextprotocol/server-filesystem", "/path/to/dir"
      ]
    },

        "--header", "Authorization: Bearer ${LINEAR_API_KEY}"
      ]
    }
  }
}

⚙️ Configuration

`mcproxy` automatically creates a `.mcproxy.json` file in your workspace to manage tool settings.
