Frameworks and protocols.

The libraries agents are built with and the open protocols they use to reach tools and each other — described from their own documentation.

Questions

  1. How do you choose an AI agent framework?

    First decide whether you need a framework at all. Then compare control, state and durability, human-in-the-loop support, language, and model lock-in.

  2. What is the Model Context Protocol (MCP)?

    MCP is an open protocol that lets AI applications connect to tools and data through one standard interface. How it works, and what it does not do for security.

  3. What is the difference between MCP and A2A?

    MCP connects an AI agent to tools and data. A2A connects agents to other agents. Why the A2A project calls them complementary, and when you need each.
