Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Bitwarden account to Claude via Composio Connect, enabling it to retrieve login details for Salesforce account, list all shared vault items this week, generate a new secure password for Dropbox, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Bitwarden account

For example, ask Claude to:

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Bitwarden account is ready to use.

What is the Bitwarden Claude Connector, and what's possible with it?

The Bitwarden MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bitwarden account. It provides structured and secure access to your encrypted vault, so your agent can perform actions like retrieving credentials, managing vault items, updating passwords, generating new secure passwords, and organizing your vault for you.

  • Secure credential retrieval: Instantly fetch login details, secure notes, or card information from your Bitwarden vault whenever your agent needs to access or autofill credentials.
  • Password management and updates: Direct your agent to update existing passwords, change login details, or rotate credentials for improved security.
  • Vault item creation and organization: Have your agent create new items—like logins, notes, or identities—and organize them into folders or collections for easy access and sharing.
  • Password generation and security checks: Use the agent to generate strong, unique passwords and even check for reused or weak credentials across your vault.
  • Automated sharing and access management: Let your agent securely share selected credentials with trusted users or teams, while maintaining detailed access controls.

Troubleshooting

1. Why does Claude not use the Composio connector for Bitwarden?

The connector can show as connected, but Claude must use it in each Bitwarden conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Bitwarden again.

2. Why does Claude show an MCP server error before Bitwarden connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Bitwarden.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Bitwarden.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Bitwarden authorization link not work?

The Composio connector is one server. Your Bitwarden account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Bitwarden connection.
  • Composio creates a fresh Bitwarden authorization link.
  • Open that link in your browser and finish the Bitwarden sign-in.

4. Why do Bitwarden actions fail after they worked before?

The Bitwarden connection can expire or lose permission.

  • Ask Claude to inspect the Bitwarden connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Bitwarden account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Bitwarden.
  • If the action still fails with a permission error, check that the connected account has that permission in Bitwarden itself.

5. How do I switch to a different Bitwarden account?

Claude can manage the Bitwarden connection for you.

  • Ask Claude to disconnect or delete the current Bitwarden account.
  • Ask Claude to connect Bitwarden again.
  • Open the new Composio authorization link for Bitwarden.
  • Sign in with the other Bitwarden account in the browser.
  • After the account connects, ask Claude to retry the Bitwarden task.

6. Why is my Bitwarden connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Bitwarden connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Bitwarden tools still do not appear, click , disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Bitwarden.

FAQ

Frequently asked questions

With a standalone Bitwarden MCP server, the agents and LLMs can only access a fixed set of Bitwarden tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Bitwarden and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Bitwarden tools.

Yes, absolutely. You can configure which Bitwarden scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Bitwarden data and credentials are handled as safely as possible.
