Switchboard

Switchboard is an MCP proxy that aggregates multiple child Model Context Protocols into single suite tools, presenting them to AI hosts like Claude Code and Cursor with on-demand subtool expansion. Instead of exposing all tools upfront, Switchboard discovers child MCPs, creates one aggregated tool per MCP, and spawns child processes only when needed—dramatically reducing token overhead. The proxy typically achieves 85-90% token reduction across typical MCP aggregations, with some large MCPs like Supabase saving 95% of tokens (20,000+ → ~1,000). Setup is zero-config: run `switchboard init` to auto-migrate existing MCP configurations, and Switchboard handles discovery, routing, and lazy initialization automatically.

Install globally via `npm install -g @george5562/switchboard`, then run `switchboard init` in your project directory to auto-migrate existing `.mcp.json` configurations. Replace your `.mcp.json` with a single switchboard entry, and restart your MCP host. Switchboard handles child MCP discovery and lazy loading automatically.
