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 connect results are stamped with the account that started them

Not switched on
Useful2 Signal3
MCP

MCP connections that finish after you switch accounts get dropped, but almost all of it is dark.

Connect attempts are stamped with their account and discarded across a switch; only the policy-blocked path runs without the disabled discovery cache.

What

Every connect attempt is tagged with the account in effect when it began; results that settle after a switch are dropped and their sockets closed instead of being written into the app's server list. Also new: cached servers are re-dialled and adopted on lazy connect, and a disable or policy denial landing mid-flight replaces the row rather than losing to the connect. Only the policy-blocked path runs on a default build; the rest sits behind the discovery cache, which is off.

Details
  • An account change bumps a process-wide counter and fires a one-shot telemetry event.
  • Mid-flight denials produce a disabled row or a POLICY_BLOCKED failed row.
Evidence

applyConnectionResult: disposing connect that settled after a disable

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