FAQ

Common questions from builders exploring A2A and MCP.

What is MCP?

MCP is a protocol for connecting AI models and agents to tools, files, databases, APIs, and other context sources through a common interface.

What is A2A?

A2A focuses on agent-to-agent interoperability, helping agents discover capabilities, delegate work, and coordinate across vendors or frameworks.

How do I choose an MCP server?

Start with the workflow you need, then check official status, recent activity, client compatibility, security notes, and installation requirements.

Can I submit a project?

Yes. Submit servers, clients, agents, frameworks, guides, and ecosystem resources for review so they can be listed in the directory.
