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 task sidecars on a newer protocol are parked instead of restored

Not switched on
Useful2 Signal4
MCP

MCP helper processes declaring a newer protocol are parked on restore, awaiting a v2 runtime.

Saved MCP task sidecars tagged with a newer 'sep2663' protocol are skipped by the current restore path with a log saying they need a v2 runtime that isn't the one restoring them.

What

Restoring MCP task helper processes from a saved session now checks which protocol each one declared. Entries on the newer sep2663 protocol are skipped by the older restore path with a log saying they need the v2 runtime.

Details
  • Any protocol value that is not recognised is parked with an error-level log rather than restored blindly.
  • Both restore paths in the bundle carry the guard.
Evidence

sep2663

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