Trivy MCP Server Plugin: Model Context Protocol Integration

Overview: What is Trivy MCP Server?

The Trivy MCP (Model Context Protocol) Server is an experimental plugin that facilitates the integration of Trivy—a powerful static analysis tool for identifying vulnerabilities and misconfigurations in software projects—into AI applications. This server acts as a gateway, enabling AI tools such as Claude Desktop, Continue, and Cursor to interact with Trivy through a standardized protocol.

🔧 Core Features & MCP Capabilities

The Trivy MCP Server leverages the Model Context Protocol (MCP) to provide seamless integration between AI applications and static analysis tools. This protocol ensures that data from various sources can be systematically analyzed and presented in a structured manner, enhancing the overall efficiency of security assessments within AI workflows.

Key Features:

• Command-Line Interface Integration: The server supports installation through Trivy’s plugin management system via trivy plugin install mcp.
• Multiple Transport Mechanisms: It allows the selection between sse (Server-Sent Events) or stdio for data transmission.
• Customizable Settings: Users can specify a custom binary path (--trivy-binary) instead of relying on core code.

MCP Capabilities:

The MCP Server supports advanced AI application features such as file system scanning, image scanning, and remote repository analysis. By leveraging these capabilities, developers can perform comprehensive security checks with ease without the need for manual intervention.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Trivy MCP Server is designed to follow the Model Context Protocol. This protocol ensures that data flows seamlessly between AI applications, static analysis tools like Trivy, and remote data sources.

🚀 Getting Started with Installation

Installing the Plugin

To get started, you need to install the Trivy MCP Server plugin. This can be done using Trivy’s built-in plugin management system:

trivy plugin install mcp

This command will ensure that the latest version of the MCP Server is installed on your system.

💡 Key Use Cases in AI Workflows

Filesystem Scanning

You can scan a local project for vulnerabilities with a simple prompt. For instance, while exploring a file explorer context, you might ask:

Are there any vulnerabilities or misconfigurations in this project?

This query triggers the MCP Server to perform an analysis of your filesystem and return detailed results.

Image Scanning

For Docker images, you can directly check for known vulnerabilities using queries like:

Does the python:3.12 image have any vulnerabilities?

The MCP Server would then execute a scan on the specified image and present the findings.

Repository Scanning

To evaluate remote repositories for security threats, consider asking questions such as:

What are the vulnerabilities in github.com/aquasecurity/trivy-ci-test

This request instructs the MCP Server to perform an analysis of the repository at github.com/aquasecurity/trivy-ci-test.

Configuration Example

Here’s an example of how to configure the Trivy MCP Server using JSON settings:

{
  "mcpServers": {
    "Trivy MCP": {
      "command": "trivy",
      "args": ["mcp", "-t", "stdio"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

📊 Performance & Compatibility Matrix

While the current version of the Trivy MCP Server is still in development, it is designed to handle a wide range of use cases. The server’s performance and compatibility matrix currently support:

• Filesystem Scans: Efficiently analyze local project files.
• Image Scans: Identify vulnerabilities in Docker images.
• Repository Scans: Secure remote repositories with comprehensive scan results.

🛠️ Advanced Configuration & Security

Customizable Environment Variables

You can customize the server by setting environment variables. For example:

export API_KEY="your-api-key"

This enables you to integrate MCP Server seamlessly into your application without modifying core code.

Security Best Practices

Ensure secure interactions and configurations, particularly when setting API keys and other sensitive information:

• API Key Management: Use a secure method for storing API_KEY values.
• Network Security: Protect network communications, especially over sse.
