VirusTotal MCP Server

A Model Context Protocol (MCP) server for querying the VirusTotal API. This server provides comprehensive security analysis tools with automatic relationship data fetching. It integrates seamlessly with MCP-compatible applications like Claude Desktop.

Quick Start (Recommended)

Claude Code

claude mcp add --transport stdio --env VIRUSTOTAL_API_KEY=your-key virustotal -- npx -y @burtthecoder/mcp-virustotal

Codex CLI

codex mcp add virustotal --env VIRUSTOTAL_API_KEY=your-key -- npx -y @burtthecoder/mcp-virustotal

Gemini CLI

gemini mcp add -e VIRUSTOTAL_API_KEY=your-key virustotal npx -y @burtthecoder/mcp-virustotal

Installing via Smithery

To install VirusTotal Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @burtthecoder/mcp-virustotal --client claude

Installing Manually

1. Install the server globally via npm:

npm install -g @burtthecoder/mcp-virustotal

2. Add to your Claude Desktop configuration file:

{
  "mcpServers": {
    "virustotal": {
      "command": "mcp-virustotal",
      "env": {
        "VIRUSTOTAL_API_KEY": "your-virustotal-api-key"
      }
    }
  }
}

Configuration file location:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

3. Restart Claude Desktop

Using with VS Code

To use this MCP server in VS Code with GitHub Copilot:

1. Install the server globally via npm:

npm install -g @burtthecoder/mcp-virustotal

2. Create or update your VS Code MCP configuration file at:

   • macOS/Linux: ~/.vscode/mcp.json
   • Windows: %USERPROFILE%\.vscode\mcp.json

3. Add the following configuration:

{
  "servers": {
    "virustotal": {
      "command": "mcp-virustotal",
      "env": {
        "VIRUSTOTAL_API_KEY": "your-virustotal-api-key"
      }
    }
  }
}

4. Reload VS Code to activate the MCP server

You can then use the VirusTotal tools through GitHub Copilot in VS Code by referencing the available tools in your prompts.

Alternative Setup (From Source)

If you prefer to run from source or need to modify the code:

1. Clone and build:

git clone <repository_url>
cd mcp-virustotal
npm install
npm run build

2. Add to your Claude Desktop configuration:

{
  "mcpServers": {
    "virustotal": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-virustotal/build/index.js"],
      "env": {
        "VIRUSTOTAL_API_KEY": "your-virustotal-api-key"
      }
    }
  }
}

HTTP Streaming Transport

The server supports HTTP streaming transport in addition to the default stdio transport. This is useful for running the server as a standalone HTTP service that multiple clients can connect to.

Running in HTTP Streaming Mode

Set the MCP_TRANSPORT environment variable to httpStream:

MCP_TRANSPORT=httpStream MCP_PORT=3000 VIRUSTOTAL_API_KEY=your-key node build/index.js

Environment Variables

Docker with HTTP Streaming

docker build -t mcp-virustotal .
docker run -p 3000:3000 \
  -e VIRUSTOTAL_API_KEY=your-key \
  -e MCP_TRANSPORT=httpStream \
  mcp-virustotal

The server exposes a health check endpoint at /health when running in HTTP streaming mode.

Features

• Comprehensive Analysis Reports: Each analysis tool automatically fetches relevant relationship data along with the basic report using VirusTotal's ?relationships= query, batched to minimize API calls
• URL Analysis: Cached-report-first lookups with automatic fallback to scanning, plus contacted domains, downloaded files, and threat actors
• File Analysis: Detailed analysis of file hashes including behaviors, dropped files, and network connections
• IP Analysis: Security reports with historical data, resolutions, and related threats
• Domain Analysis: DNS information, WHOIS data, SSL certificates, and subdomains
• Detailed Relationship Analysis: Dedicated tools for querying specific types of relationships with pagination support
• Corpus Search: Free-form search across files, URLs, domains, IPs, and comments, including VTI-style modifier syntax (type:peexe positives:5+)
• Sandbox Behaviour Summary: Cross-sandbox merged view of processes, files, registry, network, MITRE ATT&CK, IDS alerts, and signature matches
• Threat Collections: Read APT, malware-family, campaign, and intel-report objects referenced from any report's relationships
• Rich Formatting: Clear categorization and presentation of analysis results and relationship data
