I’m thrilled that Claude Code finally got MCP lazy loading via tool search. Curious for those that understand it more deeply than I do — why wouldn’t I just force enable it, rather than relying on the 10% default threshold? The default threshold seems very conservative. I’m more concerned about several smaller MCP adding up to context bloat, rather than one monster MCP using 10%+ of the context window on its own. From what I understand the tool search still gives agents a list of available tools, and they lazy load the full tool definition as needed. If so, sounds safe to force enable for all tools, but there must be a reason Claude shipped with the 10% threshold default. Lookup performance?
