## TL;DR

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

The Virustotal MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Virustotal account. It provides structured and secure access to malicious file, URL, domain, and IP analysis, so your agent can perform actions like scanning files, retrieving threat reports, investigating domains, and posting comments or verdicts on your behalf.
- Comprehensive threat analysis retrieval: Instantly fetch detailed reports on files, URLs, domains, or IP addresses to understand their security reputation and scan results from dozens of antivirus engines.
- Relationship and metadata insights: Have your agent explore related entities—such as domains linked to a file, or files associated with an IP address—along with receiving broad metadata about available VirusTotal operations.
- Automated commenting and feedback: Use your agent to post contextual comments on any analyzed resource, making collaboration and documentation of findings much easier.
- Community-driven voting: Submit harmless or malicious verdicts on files and URLs after reviewing analysis, helping to crowdsource threat intelligence and improve detection accuracy.
- Latest user comment retrieval: Let your agent pull up the most recent comments on a file, URL, domain, or IP address to quickly access community feedback and insights.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `VIRUSTOTAL_ADD_COMMENT` | Add VirusTotal Comment | Tool to add a comment to a VirusTotal resource (file, URL, domain, or IP address). Use after analyzing a resource to leave contextual feedback. Provide exactly one identifier per call. |
| `VIRUSTOTAL_ADD_VOTE` | Add Vote | Tool to add a vote (harmless/malicious) to a VirusTotal resource. Use after reviewing analysis results to submit your verdict. |
| `VIRUSTOTAL_GET_ANALYSIS` | Get Analysis Report | Tool to retrieve the analysis report of a file or URL submission. Use after obtaining an analysis ID to fetch its detailed report. Analysis results may be incomplete immediately after submission; poll until the report status is 'completed' before treating results as final. |
| `VIRUSTOTAL_GET_COMMENTS` | Get comments | Tool to retrieve the latest comments on a VirusTotal resource. Use when you need to review user-generated comments for a file, URL, domain, or IP after obtaining its identifier. |
| `VIRUSTOTAL_GET_DOMAIN_RELATIONSHIPS` | Get Domain Relationships | Tool to retrieve relationship objects for a given domain. Use when you have a domain and need to explore its related entities. |
| `VIRUSTOTAL_GET_DOMAIN_REPORT` | Get Domain Report | Tool to retrieve the analysis report of a domain. Use when you need detailed insight on a domain's reputation and analysis stats. No malicious signals on obscure or low-traffic domains may indicate limited analysis history rather than safety — treat sparse results as 'unknown', not 'safe'. Covers external OSINT only (reputation, malware, SSL posture); cannot analyze internal/private assets. |
| `VIRUSTOTAL_GET_FILE_REPORT` | Get File Report | Tool to retrieve the analysis report of a file. Use when you have a file's hash and need detailed scan metadata. Recently submitted files may return partial results; retry after a short delay before treating the report as final. |
| `VIRUSTOTAL_GET_IP_ADDRESS_RELATIONSHIPS` | Get IP Address Relationships | Tool to retrieve objects related to a specific IP address by relationship type. Use when you have an IP and need to explore connected files, URLs, or other entities. |
| `VIRUSTOTAL_GET_IP_ADDRESS_REPORT` | Get IP Address Report | Tool to retrieve the analysis report of an IP address. Use when you need detailed insight on an IP's reputation, ASN, country, and analysis stats. Low or zero detections indicate unknown risk, not safety — treat sparse data accordingly. Provides external OSINT only; insufficient as standalone compliance evidence. |
| `VIRUSTOTAL_GET_METADATA` | Get VirusTotal Metadata | Tool to retrieve VirusTotal metadata. Use when you need information about available privileges, relationships between resources (like files, domains, IPs, URLs), and supported antivirus engines. |
| `VIRUSTOTAL_GET_URL_REPORT` | Get URL Report | Tool to retrieve the analysis report of a URL. Use when you have a URL identifier (base64-url without padding) and need detailed scan results, reputation, and metadata. Results may be incomplete immediately after submission; retry with short delays if scan engines are still processing before treating the report as final. |
| `VIRUSTOTAL_GET_VOTES` | Get Votes | Tool to retrieve votes on files, URLs, domains, or IP addresses. Use when you need to view community votes for a given object. |
| `VIRUSTOTAL_RESCAN_FILE` | Rescan File | Tool to re-analyze a previously submitted file. Use when you need updated analysis results after an initial scan. |
| `VIRUSTOTAL_SCAN_URL` | Scan URL | Tool to submit a URL for scanning. Use when you have a URL and need to submit it to VirusTotal to obtain an analysis ID for later retrieval. The returned analysis ID is preliminary — scanning engines may not have finished. Poll VIRUSTOTAL_GET_URL_REPORT with the ID using short delays to retrieve complete results. |
| `VIRUSTOTAL_SEARCH` | Search VirusTotal | Tool to search for objects in the VirusTotal database. Use when locating files, URLs, domains, IPs, or comments matching a query. Supports pagination with limit and cursor. |
| `VIRUSTOTAL_UPLOAD_FILE` | Upload File | Tool to upload a file for scanning. Use when you have binary file content ready to submit for VirusTotal analysis. |

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

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

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 Virustotal 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=["virustotal"],
)

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

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

## Conclusion

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

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

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

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