How to use this MCP inside flows
Using MCP in FlowHunt
To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:
{
"malwarebazaar": {
"transport": "streamable_http",
"url": "https://yourmcpserver.example/pathtothemcp/url"
}
}
Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change “malwarebazaar” to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Based on the available documentation and code, MalwareBazaar MCP provides comprehensive tooling for malware intelligence workflows, but lacks prompt templates, explicit resource definitions, and support documentation for advanced MCP features like Roots and Sampling.
Our opinion
This MCP server is focused, well-documented for setup, and clearly provides practical tools for malware research. However, the lack of prompt and resource definitions, and no mention of Roots or Sampling, limits interoperability and advanced usage. Solid for its niche, but could improve MCP compliance.
