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 handshake timeouts are recorded as lost connections

Under the hood
Useful2 Signal2
MCP

An MCP handshake that times out is now recorded as a lost connection instead of an ordinary shutdown.

What

When an MCP handshake times out or a stale client row is cleaned up, the task is now torn down as a lost connection rather than an ordinary quiet kill, so the two causes can be told apart downstream.

Evidence

connectionLost: !0

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