How to Set Up and Use Malware Bazaar
MalwareBazaar MCP is an AI-driven MCP server that provides direct access to MalwareBazaar (abuse.ch), a community platform for sharing malware samples, through four focused tools: retrieving recent samples, fetching detailed metadata for a specific sample hash, downloading malware samples, and querying samples by tag. It is designed for authorized cybersecurity researchers and threat intelligence analysts who want to integrate real-time malware sample data into AI-assisted investigation workflows without manually navigating the MalwareBazaar web interface. Using it requires a MalwareBazaar API key and must only be done in authorized research environments.
Prerequisites
- Python 3.9 or later installed
- uv package manager installed (curl -LsSf https://astral.sh/uv/install.sh | sh on macOS/Linux)
- A MalwareBazaar API key (register and obtain from https://auth.abuse.ch/user/me)
- An MCP-compatible client such as Claude Desktop or Claude Code
- Git to clone the repository
Obtain a MalwareBazaar API key
Create an account at abuse.ch and go to https://auth.abuse.ch/user/me to generate your API key. Copy it for use in the next step.
Clone the repository
Clone the MalwareBazaar MCP repository to your local machine.
git clone https://github.com/mytechnotalent/MalwareBazaar_MCP
cd MalwareBazaar_MCPCreate a virtual environment and install dependencies
Use uv to create a virtual environment and install all required packages from requirements.txt.
uv init .
uv venv
source .venv/bin/activate
uv pip install -r requirements.txtCreate the .env file with your API key
Create a .env file in the project root containing your MalwareBazaar API key.
echo "MALWAREBAZAAR_API_KEY=your_api_key_here" > .envAdd the server to your MCP client configuration
Edit your claude_desktop_config.json to register the MalwareBazaar MCP server. Use the full path to your uv installation and the project directory.
Verify the server works
Run the server directly to confirm it starts without errors before connecting through an MCP client.
uv run malwarebazaar_mcp.pyMalware Bazaar Examples
Client configuration
Add this to your claude_desktop_config.json. Replace /Users/XXX with your actual home directory path and adjust the directory path to your clone location.

These prompts exercise all four available tools. Only use in authorized research environments.
- "Get the 10 most recent malware samples from MalwareBazaar and summarize their file types and tags"
- "Look up detailed metadata for this SHA256 hash: 44d88612fea8a8f36de82e1278abb02f"
- "Find all malware samples tagged as 'Emotet' and list their file names and upload dates"
- "What is the most common malware family in the recent samples from MalwareBazaar?"Troubleshooting Malware Bazaar
Server starts but API calls fail with 'unauthorized' or 'invalid API key' errors
Verify the MALWAREBAZAAR_API_KEY value in your .env file matches exactly what is shown at https://auth.abuse.ch/user/me. Ensure there are no extra spaces or newline characters in the key value.
uv command not found when running the server from MCP client
The MCP client config requires the full absolute path to the uv binary, not just 'uv'. Find it with: which uv. Use that full path in the command field of your config.
get_file tool downloads a file but it appears corrupted
MalwareBazaar samples are distributed as password-protected ZIP archives. The password is 'infected'. This is a standard safety measure — use an appropriate tool to extract the archive only in an isolated research environment.
