What probably matters to youSection of the release

What

MCP servers are outside tools Claude Code can connect to. This release adds code for an MCP tasks feature, controlled by switches (flags) that Anthropic's server can turn on remotely:

  • tengu_mcp_tasks: a new check guarding the MCP tasks feature. If the server gives no value, it counts as off. The code that uses this check is not visible in this release.
  • tengu_mcp_task_worker_wake: replaces tengu_ccr_context_build_after_resume_enabled at the same places in the code. It now controls how MCP tasks are woken up and retried rather than how context is built after resuming a session. When it is off, the task scheduler skips any task that is not being cancelled, so the wake and retry steps never run. It also guards two other places. It too counts as off if the server gives no value.

No reading has yet been taken of either new switch.

Why

These switches prepare a feature that is not yet active by default. Nothing changes for you unless Anthropic turns the switches on from its side.
