threat_intel_search

Search VirusTotal Intelligence with advanced queries to find files matching specific criteria for threat hunting, malware research, and IOC discovery.

Instructions

Search VirusTotal Intelligence with advanced queries for threat hunting.

This tool allows searching the entire VirusTotal dataset using powerful query syntax to find files matching specific criteria. Essential for proactive threat hunting, malware research, and discovering related samples.

Query Syntax Examples:

  • File type: type:peexe type:pdf type:apk

  • Size: size:90kb+ size:1mb-5mb

  • Detections: positives:5+ engines:kaspersky

  • Time: fs:2024-01-01+ ls:7d-

  • Behavior: behavior:"contacts C2"

  • Tags: tag:ransomware tag:trojan

  • Strings: content:"malicious string"

  • Imports: imports:CreateRemoteThread

  • Certificates: signature:"Company Name"

What this tool provides:

  • Search results matching your criteria

  • File metadata and detection statistics

  • Comprehensive threat intelligence per result

  • Ability to hunt for specific malware characteristics

  • IOC discovery and threat research capabilities

Common Use Cases:

  • Threat hunting: Find files with specific behaviors or characteristics

  • Malware research: Discover related samples and families

  • IOC expansion: Find files using known infrastructure

  • Campaign tracking: Identify malware from specific actors

  • Signature development: Research samples for detection rules

  • Incident response: Find similar threats in your environment

Args: query: VT Intelligence search query using the VirusTotal query syntax.

Returns: JSON string containing: - results: Array of matching files with full details (up to 10) - count: Number of results returned - query: The search query used

Examples: query="type:peexe size:90kb+ positives:10+" query="behavior_network:C2 tag:ransomware" query="signature:'Microsoft Corporation' positives:0"

Notes: - Requires a valid VirusTotal API key (PURPLEMCP_VT_API_KEY environment variable) - Intelligence search requires a VirusTotal Premium/Enterprise API key - Returns up to 10 results per query - Complex queries may take longer to execute - Query syntax documentation: https://docs.virustotal.com/docs/intelligence-search - IMPORTANT: Do NOT call this tool repeatedly with the same parameters. It returns the same data each time, not additional results. Use different search queries to find different files.

Raises: ThreatIntelligenceClientError: If there's an error communicating with the API. RuntimeError: If the API key is not configured or lacks Intelligence access.

Tool Definition Quality

A4.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description fully covers behavior: API key requirements, result limit (10), query complexity, warning against repeated same-parameter calls, and error types. Exceptionally transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with clear sections (Query Syntax, What this tool provides, Use Cases, Args, Returns, Notes, Raises). Slightly verbose due to extensive examples and use cases, but every part adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter tool with no annotations and no schema descriptions, the description covers input (query syntax), output (JSON structure), limitations (10 results, API key), warnings, and errors. Fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Single 'query' parameter has 0% schema coverage, but description compensates with extensive query syntax examples, covering file types, size, detections, time, behavior, tags, strings, imports, certificates—fully explaining what the parameter accepts.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it searches VirusTotal Intelligence with advanced queries for threat hunting. Distinguishes from sibling tools that search by specific indicators like hash, IP, domain, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit use cases (threat hunting, malware research, IOC expansion) and when it is essential. Lacks explicit when-not-to-use instructions, but sibling tool differentiation implies it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
