概览

What is A Simple MCP Server and Client?

This is a Model Context Protocol (MCP) server and client implementation that demonstrates how to expose and access weather information. It is intended for developers learning about MCP.

How to use A Simple MCP Server and Client?

Start the client with node client.js, which automatically starts the server as a child process. To run the server independently, use node server.js.

常见问题

What protocol does this server use?

It uses JSON-RPC 2.0 as the underlying communication protocol between client and server.

What transport mechanism is used?

This example uses stdio (standard input/output) transport. The client spawns the server as a child process and communicates through stdin/stdout streams.

How do I run the server and client?

Start the client with `node client.js`; it automatically starts the server. To run the server independently, use `node server.js`.

What resources are available?

The server provides city resources: `city://NewYork`, `city://London`, and `city://Tokyo`.

What if resource or prompt requests time out?

Check the server implementation. The example includes direct message handling to work around limitations in the current SDK version.
