 ### Reduce MCP server overhead
 
-MCP tool definitions are [deferred by default](/docs/en/mcp#scale-with-mcp-tool-search), so only tool names enter context until Claude uses a specific tool. Run `/context` to see what's consuming space.

 * **Prefer CLI tools when available**: Tools like `gh`, `aws`, `gcloud`, and `sentry-cli` are still more context-efficient than MCP servers because they don't add any per-tool listing. Claude can run CLI commands directly.
 * **Disable unused servers**: Run `/mcp` to see configured servers and disable any you're not actively using.
