DefectDojo MCP Server

This project provides a Model Context Protocol (MCP) server implementation for DefectDojo, a popular open-source vulnerability management tool. It allows AI agents and other MCP clients to interact with the DefectDojo API programmatically.

Features

This MCP server exposes tools for managing key DefectDojo entities:

• Findings: Fetch, search, create, update status, and add notes.
• Products: List available products.
• Engagements: List, retrieve details, create, update, and close engagements.

Installation & Running

There are a couple of ways to run this server:

Using `uvx` (Recommended)

`uvx` executes Python applications in temporary virtual environments, installing dependencies automatically.

uvx defectdojo-mcp

Using `pip`

You can install the package into your Python environment using `pip`.

# Install directly from the cloned source code directory
pip install .

# Or, if the package is published on PyPI
pip install defectdojo-mcp

Once installed via pip, run the server using:

defectdojo-mcp

Configuration

The server requires the following environment variables to connect to your DefectDojo instance:

• `DEFECTDOJO_API_TOKEN` (required): Your DefectDojo API token for authentication.
• `DEFECTDOJO_API_BASE` (required): The base URL of your DefectDojo instance (e.g., `https://your-defectdojo-instance.com`).

You can configure these in your MCP client's settings file. Here's an example using the `uvx` command:

{
  "mcpServers": {
    "defectdojo": {
      "command": "uvx",
      "args": ["defectdojo-mcp"],
      "env": {
        "DEFECTDOJO_API_TOKEN": "YOUR_API_TOKEN_HERE",
        "DEFECTDOJO_API_BASE": "https://your-defectdojo-instance.com"
      }
    }
  }
}

If you installed the package using `pip`, the configuration would look like this:

{
  "mcpServers": {
    "defectdojo": {
      "command": "defectdojo-mcp",
      "args": [],
      "env": {
        "DEFECTDOJO_API_TOKEN": "YOUR_API_TOKEN_HERE",
        "DEFECTDOJO_API_BASE": "https://your-defectdojo-instance.com"
      }
    }
  }
}

Available Tools

The following tools are available via the MCP interface:

• `get_findings`: Retrieve findings with filtering (product_name, status, severity) and pagination (limit, offset).
• `search_findings`: Search findings using a text query, with filtering and pagination.
• `update_finding_status`: Change the status of a specific finding (e.g., Active, Verified, False Positive).
• `add_finding_note`: Add a textual note to a finding.
• `create_finding`: Create a new finding associated with a test.
• `list_products`: List products with filtering (name, prod_type) and pagination.
• `list_engagements`: List engagements with filtering (product_id, status, name) and pagination.
• `get_engagement`: Get details for a specific engagement by its ID.
• `create_engagement`: Create a new engagement for a product.
• `update_engagement`: Modify details of an existing engagement.
• `close_engagement`: Mark an engagement as completed.

*(See the original README content below for detailed usage examples of each tool)*

Usage Examples

*(Note: These examples assume an MCP client environment capable of calling `use_mcp_tool`)*

Get Findings

# Get active, high-severity findings (limit 10)
result = await use_mcp_tool("defectdojo", "get_findings", {
    "status": "Active",
    "severity": "High",
    "limit": 10
})

Search Findings

# Search for findings containing 'SQL Injection'
result = await use_mcp_tool("defectdojo", "search_findings", {
    "query": "SQL Injection"
})

Update Finding Status

# Mark finding 123 as Verified
result = await use_mcp_tool("defectdojo", "update_finding_status", {
    "finding_id": 123,
    "status": "Verified"
})

Add Note to Finding

result = await use_mcp_tool("defectdojo", "add_finding_note", {
    "finding_id": 123,
    "note": "Confirmed vulnerability on staging server."
})

Create Finding

result = await use_mcp_tool("defectdojo", "create_finding", {
    "title": "Reflected XSS in Search Results",
    "test_id": 55, # ID of the associated test
    "severity": "Medium",
    "description": "User input in search is not properly sanitized, leading to XSS.",
    "cwe": 79
})

List Products

# List products containing 'Web App' in their name
result = await use_mcp_tool("defectdojo", "list_products", {
    "name": "Web App",
    "limit": 10
})

List Engagements

# List 'In Progress' engagements for product ID 42
result = await use_mcp_tool("defectdojo", "list_engagements", {
    "product_id": 42,
    "status": "In Progress"
})

Get Engagement

result = await use_mcp_tool("defectdojo", "get_engagement", {
    "engagement_id": 101
})

Create Engagement

result = await use_mcp_tool("defectdojo", "create_engagement", {
    "product_id": 42,
    "name": "Q2 Security Scan",
    "target_start": "2025-04-01",
    "target_end": "2025-04-15",
    "status": "Not Started"
})

Update Engagement

result = await use_mcp_tool("defectdojo", "update_engagement", {
    "engagement_id": 101,
    "status": "In Progress",
    "description": "Scan initiated."
})

Close Engagement

result = await use_mcp_tool("defectdojo", "close_engagement", {
    "engagement_id": 101
})

Development

Setup

1. Clone the repository.

2. It's recommended to use a virtual environment:

python -m venv .venv
    source .venv/bin/activate # On Windows use `.venv\Scripts\activate`

3. Install dependencies, including development dependencies:

pip install -e ".[dev]"
