mcp-assert vs mcp-use
mcp-assert: mcp-assert is a powerful tool designed to test MCP (Multi-Agent Communication Protocol) servers against the real protocol, eliminating the need for mocks or language-specific dependencies. It validates server responses against YAML-defined expectations, ensuring compatibility with all MCP clients.; mcp-use: mcp-use is a full-stack framework for Model Context Protocol (MCP), enabling the creation of MCP servers, clients, and AI agents. It supports development in both Python and TypeScript with minimal code.
