mcp-assert vs whatsapp-mcp
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.; whatsapp-mcp: The WhatsApp MCP Server connects to your personal WhatsApp account via the WhatsApp web multidevice API, storing messages locally in SQLite. It enables searching, reading, and sending messages to individuals or groups, along with media handling, through an LLM agent like Claude using standardized MCP tools.
