## Introduction

This guide walks you through connecting Bitwarden to Google ADK using the Composio tool router. By the end, you'll have a working Bitwarden agent that can retrieve login details for salesforce account, list all shared vault items this week, generate a new secure password for dropbox through natural language commands.
This guide will help you understand how to give your Google ADK agent real control over a Bitwarden account through Composio's Bitwarden MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Get a Bitwarden account set up and connected to Composio
- Install the Google ADK and Composio packages
- Create a Composio Tool Router session for Bitwarden
- Build an agent that connects to Bitwarden through MCP
- Interact with Bitwarden using natural language

## What is Google ADK?

Google ADK (Agents Development Kit) is Google's framework for building AI agents powered by Gemini models. It provides tools for creating agents that can use external services through the Model Context Protocol.
Key features include:
- Gemini Integration: Native support for Google's Gemini models
- MCP Toolset: Built-in support for Model Context Protocol tools
- Streamable HTTP: Connect to external services through streamable HTTP
- CLI and Web UI: Run agents via command line or web interface

## What is the Bitwarden MCP server, 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.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BITWARDEN_DELETE_GROUP` | Delete Group | Tool to delete a group. Use when you need to permanently remove a group by its ID after ensuring no dependencies exist. |
| `BITWARDEN_DELETE_MEMBER` | Delete Member | Tool to delete a specific organization member. Use when you need to remove a member from the organization after verifying their member ID. |
| `BITWARDEN_GET_GROUP_MEMBER_IDS` | Get Group Member IDs | Tool to retrieve the list of member IDs for a specific Bitwarden group. Use when you need only the user IDs of all members in a group. |
| `BITWARDEN_GET_ORG_SUBSCRIPTION` | Get Organization Subscription | Tool to retrieve subscription details of the current organization. Use after obtaining a valid bearer token. |
| `BITWARDEN_IMPORT_MEMBERS_AND_GROUPS` | Import Members and Groups | Tool to bulk import members and groups in a single request. Use when migrating or seeding an organization with multiple members and groups at once. Import is all-or-nothing: a single malformed entry in `members` or `groups` causes the entire request to fail. |
| `BITWARDEN_REINVITE_MEMBER` | Reinvite Member | Tool to re-send an invitation to a pending or removed member. Use when an existing member's invite needs re-issuing. |
| `BITWARDEN_RETRIEVE_GROUP` | Retrieve Group | Tool to retrieve details for a specific group. Use when you need to fetch group permissions and assigned collections by group ID after authenticating with a valid access token. |
| `BITWARDEN_RETRIEVE_MEMBER` | Retrieve Member | Tool to retrieve details for a specific member. Use after obtaining a valid member ID to get full metadata. |
| `BITWARDEN_UPDATE_MEMBER` | Update Member | Tool to update an organization member’s admin status. Use when toggling admin privileges for an existing member. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Bitwarden MCP server is an implementation of the Model Context Protocol that connects your AI agent to Bitwarden. It provides structured and secure access so your agent can perform Bitwarden operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- A Google API key for Gemini models
- A Composio account and API key
- Python 3.9 or later installed
- Basic familiarity with Python

### 1. Getting API Keys for Google and Composio

Google API Key
- Go to [Google AI Studio](https://aistudio.google.com/app/apikey) and create an API key.
- Copy the key and keep it safe. You will put this in GOOGLE_API_KEY.
Composio API Key and User ID
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings → API Keys and copy your Composio API key. Use this for COMPOSIO_API_KEY.
- Decide on a stable user identifier to scope sessions, often your email or a user ID. Use this for COMPOSIO_USER_ID.

### 2. Install dependencies

Inside your virtual environment, install the required packages.
What's happening:
- google-adk is Google's Agents Development Kit
- composio connects your agent to Bitwarden via MCP
- python-dotenv loads environment variables
```bash
pip install google-adk composio python-dotenv
```

### 3. Set up ADK project

Set up a new Google ADK project.
What's happening:
- This creates an agent folder with a root agent file and .env file
```bash
adk create my_agent
```

### 4. Set environment variables

Save all your credentials in the .env file.
What's happening:
- GOOGLE_API_KEY authenticates with Google's Gemini models
- COMPOSIO_API_KEY authenticates with Composio
- COMPOSIO_USER_ID identifies the user for session management
```bash
GOOGLE_API_KEY=your-google-api-key
COMPOSIO_API_KEY=your-composio-api-key
COMPOSIO_USER_ID=your-user-id-or-email
```

### 5. Import modules and validate environment

What's happening:
- os reads environment variables
- Composio is the main Composio SDK client
- GoogleProvider declares that you are using Google ADK as the agent runtime
- Agent is the Google ADK LLM agent class
- McpToolset lets the ADK agent call MCP tools over HTTP
```python
import os
import warnings

from composio import Composio
from dotenv import load_dotenv
from google.adk.agents.llm_agent import Agent
from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset

load_dotenv()

warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*")

GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY")
COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID")

if not GOOGLE_API_KEY:
    raise ValueError("GOOGLE_API_KEY is not set in the environment.")
if not COMPOSIO_API_KEY:
    raise ValueError("COMPOSIO_API_KEY is not set in the environment.")
if not COMPOSIO_USER_ID:
    raise ValueError("COMPOSIO_USER_ID is not set in the environment.")
```

### 6. Create Composio client and Tool Router session

What's happening:
- Authenticates to Composio with your API key
- Declares Google ADK as the provider
- Spins up a short-lived MCP endpoint for your user and selected toolkit
- Stores the MCP HTTP URL for the ADK MCP integration
```python
composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=COMPOSIO_USER_ID,
    toolkits=["bitwarden"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url,
print(f"Composio MCP URL: {COMPOSIO_MCP_URL}")
```

### 7. Set up the McpToolset and create the Agent

What's happening:
- Connects the ADK agent to the Composio MCP endpoint through McpToolset
- Uses Gemini as the model powering the agent
- Lists exact tool names in instruction to reduce misnamed tool calls
```python
composio_toolset = McpToolset(
    connection_params=StreamableHTTPConnectionParams(
        url=COMPOSIO_MCP_URL,
        headers={"x-api-key": COMPOSIO_API_KEY}
    )
)

root_agent = Agent(
    model="gemini-2.5-flash",
    name="composio_agent",
    description="An agent that uses Composio tools to perform actions.",
    instruction=(
        "You are a helpful assistant connected to Composio. "
        "You have the following tools available: "
        "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, "
        "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. "
        "Use these tools to help users with Bitwarden operations."
    ),
    tools=[composio_toolset],
)

print("\nAgent setup complete. You can now run this agent directly ;)")
```

### 8. Run the agent

Execute the agent from the project root. The web command opens a web portal where you can chat with the agent.
What's happening:
- adk run runs the agent in CLI mode
- adk web . opens a web UI for interactive testing
```bash
# Run in CLI mode
adk run my_agent

# Or run in web UI mode
adk web
```

## Complete Code

```python
import os
import warnings

from composio import Composio
from composio_google import GoogleProvider
from dotenv import load_dotenv
from google.adk.agents.llm_agent import Agent
from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset

load_dotenv()
warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*")

GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY")
COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID")

if not GOOGLE_API_KEY:
    raise ValueError("GOOGLE_API_KEY is not set in the environment.")
if not COMPOSIO_API_KEY:
    raise ValueError("COMPOSIO_API_KEY is not set in the environment.")
if not COMPOSIO_USER_ID:
    raise ValueError("COMPOSIO_USER_ID is not set in the environment.")

composio_client = Composio(api_key=COMPOSIO_API_KEY, provider=GoogleProvider())

composio_session = composio_client.create(
    user_id=COMPOSIO_USER_ID,
    toolkits=["bitwarden"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url


composio_toolset = McpToolset(
    connection_params=StreamableHTTPConnectionParams(
        url=COMPOSIO_MCP_URL,
        headers={"x-api-key": COMPOSIO_API_KEY}
    )
)

root_agent = Agent(
    model="gemini-2.5-flash",
    name="composio_agent",
    description="An agent that uses Composio tools to perform actions.",
    instruction=(
        "You are a helpful assistant connected to Composio. "
        "You have the following tools available: "
        "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, "
        "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. "
        "Use these tools to help users with Bitwarden operations."
    ),  
    tools=[composio_toolset],
)

print("\nAgent setup complete. You can now run this agent directly ;)")
```

## Conclusion

You've successfully integrated Bitwarden with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Bitwarden using natural language commands.
Key takeaways:
- The Tool Router approach dynamically routes requests to the appropriate Bitwarden tools
- Environment variables keep your credentials secure and separate from code
- Clear agent instructions reduce tool calling errors
- The ADK web UI provides an interactive interface for testing and development
You can extend this setup by adding more toolkits to the toolkits array in your session configuration.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Bitwarden MCP?

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.

### Can I use Tool Router MCP with Google ADK?

Yes, you can. Google ADK 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.

### Can I manage the permissions and scopes for Bitwarden while using Tool Router?

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.

### How safe is my data with Composio Tool Router?

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.
