Hi,
I'm using kiro IDE and I want to use certain MCP servers only in a subagent because this MCP server comes with dozens of tools that are not needed most of the time.

How can I use a MCP server that's disabled in MCP.json in a subagent?

Hi. Might you be after Kiro Powers? https://kiro.dev/docs/powers/

I don't think a disabled tool will work for a subagent, though you can specify it
