A2A 1.1 turns a task into a shared workspace. The sender field is still an open PR.

The 1.1 branch has merged an ordered task timeline, a live channel and client-written artifacts. Attribution is still under review, and of 1,722 endpoints with a usable probe result in our registry, only 221 reject anonymous callers.

MCP

780 agent hosts publish an AI Catalog. Seven use it to list several agents on one host.

A2A's 1.1 branch now prefers AI Catalog over the one-card-per-domain well-known path. We checked all 4,846 hosts with a valid card: catalogs are already common, but they mostly index MCP and API artifacts, and a related spec tells publishers to use a different path.

MCP

Smithery MCP connections retire October 31. Check what you use.
