When you turn one on or off and Claude Code cannot find it, it used to report `Server not found` straight away. Now, for some server names it recognises, it clears related state before reporting the error.\n\n**Why**\n\nThis probably stops a server that no longer exists from staying stuck as disabled.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
