The support here is really weird.

If I understand correctly, it requires your MCP server to have exactly two tools - search and fetch.

So this is not really support for MCP in general, as in all the available MCP servers. It’s support for their own custom higher-level protocol built on top of MCP.

Yeah I hope they open up support to all MCP tools - this is lame as-is.

this guide is just for an example of how to build a single mcp (e.g. a vector store). chatgpt connectors implement mcps in general now

Is it safe to say that MCP has "won" vs. A2A? Or is this a misreading of the situation?

They're not directly solving the same problem. MCP is for exposing tools, such as reading files. a2a is for agents to talk to other agents to collaborate.

MCP servers can expose tools that are agents, but don't have to, and usually don't.

That being said, I can't say I've come across an actual implementation of a2a outside of press releases...

I don’t believe this is the case. Do you have a link for that?

Cause from TFA “To work with ChatGPT Connectors or deep research (in ChatGPT or via API), your MCP server must implement two tools - search and fetch.”

Also, this page is actually the only docs site about MCP they have, and their help articles link to it too.
