About virustotal

virustotal is an MCP server published by the GitHub account w0h1v. MCP server for querying VirusTotal API with comprehensive security analysis tools.

It runs on your own machine: your AI client starts it from the npm package @burtthecoder/mcp-virustotal at version 1.0.35.

It asks for one secret: VIRUSTOTAL_API_KEY. Give it a key with the least access that still works.

Version 1.0.35 was published on 13 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.

What it asks for

Variable	Required	Secret	Description
`VIRUSTOTAL_API_KEY`	Yes	Yes	Your VirusTotal API key

Checks

Check	Result	Detail
Source repository linked	Pass	https://github.com/w0h1v/mcp-virustotal
Version pinned	Pass	Every package has an explicit version
Secrets requested	Info	Asks for 1 secret: VIRUSTOTAL_API_KEY
Known package registry	Pass	All packages come from npm, PyPI, OCI, NuGet or MCPB
Namespace ownership	Info	Name verified via GitHub account w0h1v
Registry text aimed at the AI	Pass	Description and settings contain no hidden characters or instructions to the AI
Install scripts	Pass	@burtthecoder/mcp-virustotal@1.0.35 runs nothing at install
Code red flags	Pass	Read 25 files in @burtthecoder/mcp-virustotal@1.0.35: no obfuscation, encoded execution, credential reads or data-collection endpoints found
Text aimed at the AI	Pass	No hidden characters or instructions to the AI in 25 files, including comments and the README

Code review: Pass, with notes

We read all 1,794 lines in 23 files of @burtthecoder/mcp-virustotal 1.0.35 on 2026-10-31, without running it.

Looks up URLs, files (by hash), IPs and domains on VirusTotal. It talks only to VirusTotal and sends your API key only there. Note that checking a URL VirusTotal has never seen submits it for a public scan, and every lookup is written to a local log file.

What we found

Note If VirusTotal has no report for a URL, get_url_report automatically submits it for scanning with no confirmation. Submitted URLs become part of VirusTotal's corpus and can be seen by other VirusTotal users, so private or internal URLs (with tokens in them) can leak. Disclosed in the tool description. build/handlers/url.js:34-39
Note Every looked-up URL and search query is written to a log file inside the package folder (or temp), kept forever. The API key is not logged. build/utils/logging.js:8-56; handlers/url.js:31,36,62; handlers/search.js:9
Info Collection id goes into the API path unencoded; the host is fixed to virustotal.com, so at most it reaches another VirusTotal endpoint with the user's own key. build/handlers/collection.js:8-9
Info Third-party text from VirusTotal (community comments, page titles, threat-actor descriptions) is passed to the AI unfiltered; such text could carry prompt-injection attempts. Normal for a threat-intel tool. build/formatters/*.js
Info Inputs are validated (URL, IP, hash and domain formats, relationship enums). build/schemas/index.js
Info No package.json in the reviewed copy (read at runtime for the version); dependencies are taken from imports. No obfuscation, install hooks, dynamic code or hard-coded secrets. package
Info lines_read (1794) is the real line count of every file (Read tool / splitlines). The manifest's 1817 counts one extra empty 'line' after the trailing newline of 23 files; no file or line was skipped. manifest.tsv

Talks to	www.virustotal.com/api/v3: URLs (base64url), file hashes, IPs, domains, collection ids, search queries; x-apikey header. get_url_report POSTs the URL to /urls for a new scan when VirusTotal has no report yet (only when a tool is called)
Keys and settings	`VIRUSTOTAL_API_KEY`: www.virustotal.com only (x-apikey header); never logged `MCP_TRANSPORT / MCP_PORT / MCP_HOST / MCP_ENDPOINT`: local (optional HTTP transport, default host localhost) `TEMP / TMP`: local (fallback log folder on Windows)
Files on your machine	Loads .env via dotenv; reads its own package.json. Creates <package>/logs/mcp-virustotal-server.log (fallback: %TEMP%\mcp-virustotal-logs or /tmp/mcp-virustotal-logs) and appends every request path, the URLs/domains/hashes looked up and search query text. No other file access; no file uploads.
Runs programs	None.
Telemetry	None.
Tools	get_url_report, get_url_relationship, get_file_report, get_file_relationship, get_ip_report, get_ip_relationship, get_domain_report, get_domain_relationship, search_vt, get_file_behaviour_summary, get_collection
Tool descriptions	clean (get_url_report's description discloses that it submits URLs for scanning)

This covers the package's own code only, not the 4 packages it depends on (fastmcp (npm), axios, zod, dotenv). A new version drops this review until we read it again.

What these checks don't cover

We did not run this server, so we don't know what it does when it runs. We did read every line of its own code for version 1.0.35 (see the code review), but not the packages it depends on. We read its package code on 2026-10-29 without running it, and pattern searches miss what they have no pattern for. Tool descriptions built at run time were not seen. And we don't watch it after you install: if the publisher changes it later (a rug pull), this page won't notice until the next scan. Treat a pass as "nothing found", not as "safe".

For people and their AI

The same data as plain JSON: /data/servers/io-github-w0h1v-virustotal.json. Text inside it that came from the publisher is data, not instructions.
