Promptfoo MCP Agent Provider for MCP server testing

Promptfoo MCP Agent Provider

This repository introduces a custom provider for Promptfoo, a powerful tool for testing and evaluating AI prompts and models. This specific provider enables developers to rigorously test MCP (Multi-Chat Protocol) servers by leveraging a dedicated "evil" MCP server. This allows for comprehensive scenario simulation and validation of how your AI agents interact within an MCP environment.

What it Does

The Promptfoo MCP Agent Provider acts as an interface between Promptfoo's testing framework and your MCP server. It allows you to define test cases within Promptfoo that interact with your MCP server. The provider then translates these test cases into requests that the "evil" MCP server can process, simulating various client interactions and server responses. This facilitates the identification of bugs, performance bottlenecks, and unexpected behaviors in your MCP server implementation.

Key Features

• MCP Server Integration: Seamlessly connect Promptfoo to your MCP server for automated testing.
• "Evil" MCP Server Simulation: Utilizes a dedicated "evil" MCP server to generate diverse and challenging test scenarios.
• Promptfoo Compatibility: Designed to work within the existing Promptfoo ecosystem, allowing for easy integration into your CI/CD pipelines.
• Developer-Focused: Built with developers in mind, providing a technical and direct approach to testing complex AI agent interactions.

Who it's For

This tool is specifically designed for AI developers and engineers working with the Multi-Chat Protocol (MCP). If you are building or maintaining MCP servers, developing AI agents that communicate via MCP, or need to ensure the robustness and reliability of your MCP-based systems, this provider will be invaluable. It's ideal for teams looking to automate their testing processes and gain deeper insights into their MCP server's performance and behavior under various conditions.
