## TL;DR

Here's what you'll learn:
- Get and set up your Claude/Anthropic and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Virustotal
- Configure an AI agent that can use Virustotal as a tool
- Run a live chat session where you can ask the agent to perform Virustotal operations

## What is Claude Agent SDK?

The Claude Agent SDK is Anthropic's official framework for building AI agents powered by Claude. It provides a streamlined interface for creating agents with MCP tool support and conversation management.
Key features include:
- Native MCP Support: Built-in support for Model Context Protocol servers
- Permission Modes: Control tool execution permissions
- Streaming Responses: Real-time response streaming for interactive applications
- Context Manager: Clean async context management for sessions

## 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:
- Composio API Key and Claude/Anthropic API Key
- Primary know-how of Claude Agents SDK
- A Virustotal account
- Some knowledge of Python

### 1. Getting API Keys for Claude/Anthropic and Composio

Claude/Anthropic API Key
- Go to the [Anthropic Console](https://console.anthropic.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

## 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 Claude Agent SDK?

Yes, you can. Claude Agent SDK 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.
