Claude Code context strategy: CLI > API > MCP due to context window overhead

March 30, 2026Aakash Gupta

Aakash Gupta attributes to Andrej Karpathy a hierarchy for tool connection where MCP is last because it consumes context continuously. The takeaway is to prefer CLI/API integrations to preserve context window for actual work.

Andrej Karpathy said it himself. The hierarchy for connecting tools to Claude Code: CLI at the top, API in the middle, MCP at the bottom.
MCPs eat context the moment they connect.
Every MCP you load is sitting in your context window doing nothing until you call it.
