firefox-devtools-mcp vs fastmcp
firefox-devtools-mcp: Firefox DevTools MCP is a Model Context Protocol server that automates Firefox using WebDriver BiDi through Selenium. It enables AI assistants like Claude to control browser actions such as navigation, screenshots, and network monitoring. It integrates with various MCP clients including Claude Code, Cursor, and Cline.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
