What is MCP Client Router?
The MCP Client Router is a transport interface that unifies multiple Model Context Protocol (MCP) clients, allowing seamless interaction with various MCP servers. It routes calls, tools, and resources to the correct client based on prefix conventions, supporting both HTTP and stdio protocols. This setup enables developers to aggregate multiple MCP services, manage connections efficiently, and imitate a single MCP client for complex applications. The router handles task routing, provides a unified API, and supports flexible configuration via code or configuration objects, streamlining multi-server MCP integrations.
Who will use MCP Client Router?
- Developers integrating multiple MCP services
- Teams managing complex MCP-based architectures
- Organizations needing unified MCP client interfaces
- API integrators working with MCP protocols
How to use the MCP Client Router?
- Step 1: Install the MCP Client Router package using npm.
- Step 2: Create individual MCP clients and connect them via transports like stdio or HTTP.
- Step 3: Initialize the MCP Client Router with these clients.
- Step 4: Use the router to list tools, prompts, or resources with prefixed names.
- Step 5: Call or request resources via the router, which routes to the correct MCP client based on naming prefixes.
- Step 6: Close connections when finished.
