Package (npm 2.5.0)

npx -y @takescake/1password-mcp@2.5.0

Or add to your MCP client config:

{
  "mcpServers": {
    "1password-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@takescake/1password-mcp@2.5.0"
      ],
      "env": {
        "OP_SERVICE_ACCOUNT_TOKEN": "<YOUR_VALUE>",
        "OP_KEYCHAIN_SERVICE": "<YOUR_VALUE>",
        "OP_KEYCHAIN_ACCOUNT": "<YOUR_VALUE>"
      }
    }
  }
}

OP_SERVICE_ACCOUNT_TOKEN secret — The Service Account Token from 1Password (required unless OP_KEYCHAIN_SERVICE is used on macOS)
OP_KEYCHAIN_SERVICE — macOS only: Keychain service name to read the 1Password service account token from when OP_SERVICE_ACCOUNT_TOKEN is not set
OP_KEYCHAIN_ACCOUNT — macOS only: Optional Keychain account name to narrow the lookup used with OP_KEYCHAIN_SERVICE
