Onepassword MCP Server

🚀 OnePassword MCP Server

This is a proof-of-concept server designed solely for educational purposes. It securely fetches credentials from your 1Password account using the 1Password Python SDK and provides them to Agentic AI via the MCP Python SDK for execution.

🚀 Quick Start

Installation via Smithery

To automatically install the 1Password credential retrieval server for Claude Desktop via Smithery:

npx -y @smithery/cli install @dkvdm/onepassword-mcp-server --client claude

Prerequisites

• Python 3.11 or higher
• uv (a fast Python package installer): pip install uv
• Install packages: uv sync
• Create a vault named AI in 1Password and add the projects you want to use.
• Create a service account and grant it appropriate permissions in the relevant vault to use the SDK.
• Obtain your service account token and configure the client (e.g., Claude Desktop) to connect to this server. Add the following structure to the client's configuration file (e.g., claude_desktop_config.json), adjusting the paths and environment variables as needed:

// Example configuration for Claude Desktop
{
  "mcpServers": {
    "1Password": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "--with",
        "onepassword-sdk",
        "mcp",
        "run",
        "/your/dir/here/onepassword-mcp-server/server.py" // Adjust this path as needed
      ],
      "env": {
        "OP_SERVICE_ACCOUNT_TOKEN": "INSERT_KEY_HERE" // Insert your 1Password service account token here
      }
    }
  }
}

• Start Claude and try a prompt like "Get 1Password credentials for ticktick.com" (based on the project name)

Using 1Password and Browser-Use for Automated Browsing

Install mcp-browser-use and configure two MCP servers as follows:

// Example configuration for Claude Desktop
{
  "mcpServers": {
    "1Password": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "--with",
        "onepassword-sdk",
        "mcp",
        "run",
        "/your/dir/here/onepassword-mcp-server/server.py" // Adjust this path as needed
      ],
      "env": {
        "OP_SERVICE_ACCOUNT_TOKEN": "INSERT_KEY_HERE"
      }
    },
    "browser-use": {
      "command": "uv",
      "args": [
        "--directory",
        "/your/dir/here/mcp-browser-use",
        "run",
        "mcp-server-browser-use"
      ],
      "env": {
        "MCP_USE_OWN_BROWSER": "true",
        "CHROME_CDP": "http://127.0.0.1:9222",
        "ANTHROPIC_API_KEY": "INSERT_KEY_HERE"
      }
    }
  }
}
