This is in addition to the existing rule that allowed a plain path with no query parameters.\n\n**Why**\n\nThis lets Claude Code connect to Toolbox MCP servers identified by this URL format, which it previously would not have recognized as valid.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5"}
