real-browser-mcp vs fastmcp
real-browser-mcp: Real Browser MCP bridges AI coding agents to your actual Chrome browser. It uses a Chrome extension and an MCP server to let agents see, interact with, and navigate your existing browser with all your sessions and cookies. No need to launch a separate headless browser; it works with your logged-in state.; 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.
