Common questions

Is Virustotal safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: VIRUSTOTAL_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.17) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Quickstart · Tools · HTTP · Security · Troubleshooting · Docs

mcp-virustotal is an MCP server that gives AI agents access to the VirusTotal v3 API. Hand your agent a hash, URL, IP or domain and get back the detection report plus the relationships an analyst would pivot on: contacted hosts, dropped files, resolutions, threat actors.

[!NOTE]

Independent project, not affiliated with VirusTotal or Google. You need your own VirusTotal API key.

Highlights

Reports with relationships. File, URL, IP and domain reports fetch key relationships in one batched ?relationships= call to save quota.
Cache first. get_url_report returns the cached VirusTotal report and only submits a scan on a cache miss.
Pivot tools. Corpus search with VTI-style modifiers (type:peexe positives:5+), merged sandbox behaviour summaries, and threat-actor and malware-family collections.
Full relationship paging. 100+ relationship types across files, URLs, IPs and domains, with cursor pagination.
Two transports. stdio for desktop clients, HTTP streaming for a shared service.
Tested. Unit tests for the formatters and API layer run in CI on Node 20, 22 and 24.

How it works

flowchart LR

Quickstart

Requirements: Node.js 20 or newer and a VirusTotal API key.

# 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

For Claude Desktop, VS Code and running from source, see Connect a client.

Then ask your agent: *"Look up the SHA-256 275a021bbfb6489e54d471899f7db9d1663fc695ec2fe2a2c4538aabf651fd0f (the EICAR test file) and show what it drops and contacts."*

Tools

Eleven tools. Full parameters and relationship lists are in the tool reference.

Group	Tools
Reports (with relationships)	`get_file_report`, `get_url_report`, `get_ip_report`, `get_domain_report`
Relationship paging	`get_file_relationship`, `get_url_relationship`, `get_ip_relationship`, `get_domain_relationship`
Search and pivot	`search_vt`, `get_file_behaviour_summary`, `get_collection`

HTTP streaming transport

stdio is the default. Set MCP_TRANSPORT=httpStream to run a standalone HTTP service:

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

docker build -t mcp-virustotal .

docker run -p 127.0.0.1:3000:3000 -e VIRUSTOTAL_API_KEY=your-key -e MCP_TRANSPORT=httpStream mcp-virustotal

A health check is served at /health.

Environment variables

Variable	Default	Description
`VIRUSTOTAL_API_KEY`	(required)	Your VirusTotal API key
`MCP_TRANSPORT`	`stdio`	`stdio` or `httpStream`
`MCP_HOST`	`localhost`	Bind address (`httpStream` only). The Docker image sets `0.0.0.0`
`MCP_PORT`	`3000`	HTTP port (`httpStream` only)
`MCP_ENDPOINT`	`/mcp`	HTTP endpoint path (`httpStream` only)

Security

[!WARNING]

The HTTP transport has no authentication. Keep the port on localhost or behind an authenticating reverse proxy, or anyone who can reach it can spend your API quota.

Tool arguments are validated with zod schemas before any request is built.
The API key is read from the environment and sent only to VirusTotal.
Lookups send your indicators to VirusTotal. A URL scan on a cache miss submits that URL for analysis.

Report vulnerabilities privately; see SECURITY.md.

Troubleshooting

Wrong API key: the key is usually 64 characters with no spaces or quotes. Restart the client after changing config.
429 errors: the public tier allows 4 requests per minute.
Logs: logs/mcp-virustotal-server.log in the package directory.

Development

git clone https://github.com/w0h1v/mcp-virustotal && cd mcp-virustotal

npm ci npm test # build + unit tests, no key or network VIRUSTOTAL_API_KEY=your-key npm run smoke # all 11 tools against the real API

The smoke test paces calls at 20 s for the public-tier limit and isn't suited to free tiers reduced to a few lookups a day. See CONTRIBUTING.md and the changelog.
