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.

Reconnecting a disabled MCP server tells you to enable it

You'll notice
Useful3 Signal0
MCP

Reconnecting a disabled MCP server now just tells you to enable it first.

/mcp
What

The /mcp reconnect flow checks the server's status first, and a disabled server reports that it needs enabling instead of running the reconnect state machine.

Details
  • status check happens before any reconnect attempt, so no connection cycle is started for a disabled server
  • the message points you back at /mcp to enable the server
  • other statuses still go through the normal reconnect path
Evidence

enable it in /mcp first

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