Model Context Protocol (MCP) adoption is skyrocketing, NPM installations are up to 4.7m for the week of July 7th, 2025. Today we're announcing the Promptfoo MCP Proxy to manage the security risks for enterprises using MCP servers. MCP servers aren't inherently insecure, but the way they're being used creates huge vulnerabilities. Through our work with some of the world's largest companies, we've discovered alarmingly insecure patterns.
Think of A2A (Agent2Agent) like a universal translator for AI agents. Just as a translator helps people speaking different languages understand each other, A2A helps AI agents from different companies work together smoothly. It's Google's way of making sure AI assistants can talk to each other, no matter who created them.
Modern AI models are incredibly powerful at understanding and generating text, code, and ideas. But to be truly useful, they need to connect with the real world - to read your code, query your database, or send messages to your team. This is where Model Context Protocol (MCP) comes in.
MCP is an open standard that creates a common language between AI systems and the tools they need to help you. It defines clear rules for how AI assistants can securely access and work with external resources, from local files to cloud services. Think of it as building bridges between AI models and the digital world around them.
