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.

Long-running MCP tools are wired to surface as background tasks in interactive sessions

Not switched on
Useful3 Signal3
MCP

Slow MCP tools are wired to appear as background tasks in interactive sessions.

The MCP call wrapper now carries a background-task handle, but nothing requests a task in this build.

What

The MCP call wrapper now carries a background-task handle and the application state setter, so a slow MCP tool could show up as a task in an ordinary interactive session. Subagent calls and non-interactive sessions are excluded.

Details
  • The existing auto-background delay for MCP calls is passed alongside the new handle.
  • Subagent calls are identified by the call carrying an agent id.
  • The task pathway this feeds is not requested by anything in this build.
