MCP Orchestrator
A central hub that connects to multiple downstream MCP servers, aggregates their tools, and provides unified access with powerful tool search capabilities.
Built around deferred tool loading — search across all your servers without blowing Claude's context window.
Features

- Tool Namespacing: Automatic
server_name__tool_nameformat - Tool Search: Unified BM25/regex search with deferred loading support
