Quick Start
Prerequisites
- Python 3.11 or higher
uv(fast Python package installer):pip install uv- Install packages:
uv sync - Create a vault within 1Password named
AI, and add the items you want to use. - Create a service account and give it the appropriate permissions in the vaults where the items you want to use with the SDK are saved.
- Provision your service account token, and configure clients like Claude Desktop to connect to this server. Add the following structure to the client's configuration (e.g.,
claude_desktop_config.json), adjusting the path and environment variables as needed:
// Example for Claude Desktop config
{
"mcpServers": {
"1Password": {
"command": "uv",
"args": [
"run",
"--with",
"mcp[cli]",
"--with",
"onepassword-sdk",
"mcp",
"run",
"/your/dir/here/onepassword-mcp-server/server.py" // Change this path
],
"env": {
"OP_SERVICE_ACCOUNT_TOKEN": "INSERT_KEY_HERE" // Insert 1Password Service Account Token
}
}
}
}
- Launch Claude and try a prompt such as "Get 1Password credentials for ticktick.com" (based on item name)
Automate Browser with 1Password and Browser-Use MCP
Install mcp-browser-use and configure both MCP servers as such:
// Example for Claude Desktop config
{
"mcpServers": {
"1Password": {
"command": "uv",
"args": [
"run",
"--with",
"mcp[cli]",
"--with",
"onepassword-sdk",
"mcp",
"run",
"/your/dir/here/onepassword-mcp-server/server.py"
],
"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",
"PYTHONIOENCODING": "utf-8",
"PYTHONUNBUFFERED": "1",
"PYTHONUTF8": "1"
}
}
}
}
- Launch Claude and try a prompt such as "get 1Password credentials for ticktick.com and log into https://ticktick.com/signin"
