Im not sure i understand how it coexists with existing installed MCP servers

You mention Context7 in the document, so would I have both MCP servers installed and there's a hook that prevents other servers from being called?

Context Mode doesn't replace your other MCP servers — it sits alongside them. Your Context7, Playwright, GitHub servers all stay installed and work normally. The hook intercepts output-heavy tool calls (like WebFetch, curl) and redirects them through the sandbox. For example, instead of WebFetch dumping 56KB of raw HTML into context, the hook blocks it and tells the model to use fetch_and_index instead — which fetches the same URL but indexes it in a local SQLite DB, returning only a 3KB summary.

Your other MCP servers still run. Context Mode just gives the model a more context-efficient way to process their results when the output would be large.
