What I do to keep MCP context usage under control is: 1) Enable every MCP server you want 2) Disallow tool usage on your main agent 3) Create sub-agents that are designated to just use that MCP toolset by overriding the disallow with an allow of the MCP tool list. I have one for gitlab (which has over a hundred tools), one for sound generation, one for image generation, etc.
