Gmail create_draft threadId parameter missing

[johngroves]

At some point over the past few days, the API for Gmail draft creation was changed and the threadId parameter no longer exists for the MCP server here: https://gmailmcp.googleapis.com/mcp/v1

This is a critical capability, is there a fix that can be made?

The API schema was definitely changed around April 17th, and replying within a thread (create_draft with threadId) support was completely dropped.

I've added a bug here: https://issuetracker.google.com/issues/505419344
