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 explains cross-session enable/disable drift

You'll notice
Useful3 Signal0
MCP

/mcp gains clearer messages for cross-session enable/disable conflicts and servers blocked by managed policy.

/mcp
What

New messages cover the cases where an enable or disable in one session conflicts with what another session has already done.

Details
  • Distinct text for a server another session disabled, and for one another session re-enabled so your disable did not persist.
  • Separate text for a server blocked by managed policy.
  • None of these strings exist in the previous build.
Evidence

was disabled in another session

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