Claude Code asks each one for its list of tools. It now waits for that request to finish and, if it is still the latest request, clears any earlier tool-list error or sign-in failure for that server.\n\n**Why**\n\nAn MCP server that had an error once and then recovered no longer goes on showing the old error.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
