DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

MCP servers can ask for input from inside a task

MCP

MCP servers can now ask you for input from inside a running task.

What

MCP prompts for user input (elicitation/create) are now resolved per request rather than through a shared handler, and MCP tasks get their own resolver that also serves roots/list.

Details
  • The resolver receives the server name, request parameters, request id and a cancellation signal.
  • Any other method is declined with a message naming the request and the unsupported method.
  • In a non-interactive session with no UI to prompt in, the request is logged and dropped instead of hanging.
Evidence

input request '${e}' has unsupported method ${t.method}

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
