Bitwarden is an open source password manager that helps users securely store and share sensitive information. It's used by individuals, teams, and businesses to manage passwords, credit cards, and other credentials. The app aims to simplify password management and improve online security.

Bitwarden Overview

• Vault — stores login credentials and other sensitive information
• Items — individual records within the vault, such as logins, notes, cards, or identities.
• Organizations — allow sharing items with multiple users
• Collections — within organizations, used to further organize and manage access to items.

Use action names and parameters as needed.

Working with Bitwarden

This skill uses the Membrane CLI to interact with Bitwarden. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.

Install the CLI

Install the Membrane CLI so you can run membrane from the terminal:

npm install -g @membranehq/cli

First-time setup

membrane login --tenant

A browser window opens for authentication.

Headless environments: Run the command, copy the printed URL for the user to open in a browser, then complete with membrane login complete .

Connecting to Bitwarden

• Create a new connection:

membrane search bitwarden --elementType=connector --json

Take the connector ID from output.items[0].element?.id, then:

membrane connect --connectorId=CONNECTOR_ID --json

The user completes authentication in the browser. The output contains the new connection id.

Getting list of existing connections

When you are not sure if connection already exists:

• Check existing connections:

membrane connection list --json

If a Bitwarden connection exists, note its connectionId

Searching for actions

When you know what you want to do but not the exact action ID:

membrane action list --intent=QUERY --connectionId=CONNECTION_ID --json

This will return action objects with id and inputSchema in it, so you will know how to run it.

Popular actions

Use npx @membranehq/cli@latest action list --intent=QUERY --connectionId=CONNECTION_ID --json to discover available actions.

Running actions

membrane action run --connectionId=CONNECTION_ID ACTION_ID --json

To pass JSON parameters:

membrane action run --connectionId=CONNECTION_ID ACTION_ID --json --input "{ \"key\": \"value\" }"

Proxy requests

When the available actions don't cover your use case, you can send requests directly to the Bitwarden API through Membrane's proxy. Membrane automatically appends the base URL to the path you provide and injects the correct authentication headers — including transparent credential refresh if they expire.

membrane request CONNECTION_ID /path/to/endpoint
