SineFrame M3

M3 provides a robust testing framework for MCP (Multi-Agent Communication Protocol) servers, ensuring that agent tools are called correctly and function as expected. Key features include: * Directly test server behavior with real agent code * Assert on actual tool calls made by agents * Integrate with pytest for familiar testing workflows * Visualize trace and tool call data in a dedicated user interface * Gate pull requests with CI/CD integration for quality assurance M3 addresses the critical challenge where MCP unit tests might pass, but the agent fails to invoke the necessary tool. By running your server through genuine agent code such as Claude Code, Codex, OpenCode, or Pi, M3 verifies that agents interact with your tools as intended. It captures every tool call, flagging when a server was skipped and ensuring that agents don't rely solely on their internal knowledge when a specific tool interaction is required. This focus on real-world agent execution helps catch broken MCP behavior before it impacts users. This framework is ideal for development teams building and maintaining MCP servers, particularly those working with various coding agents. It ensures server reliability, agent-tool synergy, and streamlined deployment. The platform offers a powerful UI for debugging and a CI test upload feature to maintain continuous code quality.
