## TL;DR

Here's what you'll learn:
- Get a Dropcontact account set up and connected to Composio
- Install the Google ADK and Composio packages
- Create a Composio Tool Router session for Dropcontact
- Build an agent that connects to Dropcontact through MCP
- Interact with Dropcontact 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 Dropcontact MCP server, and what's possible with it?

The Dropcontact MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dropcontact account. It provides structured and secure access to contact enrichment and B2B email finding, so your agent can perform actions like verifying professional email addresses, enriching contact lists, tracking enrichment status, and managing webhook subscriptions on your behalf.
- Batch contact enrichment: Instantly enrich up to 250 contacts at once with validated email addresses and company details, letting your agent automate lead research and CRM updates.
- Email verification and validation: Ensure the emails in your contact lists are professional and verified, reducing bounce rates and improving outreach quality.
- Retrieve enrichment results: Have your agent fetch completed enrichment data for submitted requests, so you can quickly access up-to-date contact intelligence.
- Manage webhook subscriptions: List and inspect your webhook subscriptions, making it easy to keep track of automated updates and integrations with your workflow.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `DROPCONTACT_CREATE_WEBHOOK_SUBSCRIPTION` | Create Webhook Subscription | Tool to create a new webhook subscription for receiving automatic notifications when enrichment results are ready. Use this instead of polling GET /v1/enrich/all to receive push notifications when contact enrichment processing completes. Currently only supports 'enrich_api_result' event type. |
| `DROPCONTACT_DELETE_WEBHOOK_SUBSCRIPTION` | Delete Webhook Subscription | Tool to delete a webhook subscription. Use when you need to remove a configured webhook and stop receiving notifications. Alternatively, you can pause a subscription by setting it to inactive using the update endpoint. |
| `DROPCONTACT_ENRICH_CONTACTS` | Initiate Contact Enrichment | Initiates asynchronous batch enrichment for up to 250 contacts with email finding, validation, and company information. Returns a request_id that must be used with the 'Retrieve Enrichment Results' action to fetch the enriched data. Each contact needs at least one of: email, OR (first_name + last_name + company), OR (full_name + company), OR LinkedIn URL. The enrichment typically completes within 30-60 seconds depending on batch size. |
| `DROPCONTACT_LIST_WEBHOOK_SUBSCRIPTIONS` | List Webhook Subscriptions | Tool to list webhook subscriptions. Use when you need to inspect your configured webhooks. |
| `DROPCONTACT_LIST_WEBHOOK_SUBSCRIPTIONS_V2` | List Webhook Subscriptions V2 | Tool to list all webhook subscriptions configured for the account. Returns webhook URLs, event types, and subscription details. Use when you need to inspect your configured webhooks. |
| `DROPCONTACT_RETRIEVE_ENRICHMENT_RESULTS` | Retrieve Enrichment Results | Retrieves enriched contact data by request ID after submitting contacts for enrichment. Use this tool to fetch the results of a contact enrichment request created with the 'Batch Enrich Contacts' action. The enrichment process may take 30-60 seconds. If the request is still processing, the response will indicate 'success=false' with a reason message. Once complete, you'll receive enriched data including emails with qualification status, LinkedIn profiles, company information, phone numbers, and location details. Note: You can retrieve partial results even if all contacts haven't been processed yet. |
| `DROPCONTACT_UPDATE_WEBHOOK_SUBSCRIPTION` | Update Webhook Subscription | Tool to update an existing webhook subscription. Use when you need to modify the callback URL, rate limiting settings, or active status. The event_type field cannot be changed after creation. |

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

The Dropcontact MCP server is an implementation of the Model Context Protocol that connects your AI agent to Dropcontact. It provides structured and secure access so your agent can perform Dropcontact 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 Dropcontact 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=["dropcontact"],
)

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 Dropcontact 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=["dropcontact"],
)

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 Dropcontact operations."
    ),  
    tools=[composio_toolset],
)

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

## Conclusion

You've successfully integrated Dropcontact with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Dropcontact using natural language commands.
Key takeaways:
- The Tool Router approach dynamically routes requests to the appropriate Dropcontact 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 Dropcontact MCP?

With a standalone Dropcontact MCP server, the agents and LLMs can only access a fixed set of Dropcontact tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Dropcontact 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 Dropcontact tools.

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

Yes, absolutely. You can configure which Dropcontact 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 Dropcontact data and credentials are handled as safely as possible.
