MCP-SSE sample

This demonstrates a working pattern for SSE-based MCP servers and standalone MCP clients that use tools from them.

Caution: MCP SSE is being deprecated, they are recommending to use Streamable-Http and this repo is just an exercise!

Node setup via nvm

nvm use 22

Project base setup

Install the required dependencies using npm:

npm install
cp .env.example .env

Build the Project

Compile the TypeScript code into JavaScript:

npm run build

This will generate the compiled files in the dist directory.

5. Run the Server

Start the server in production mode:

npm start

Alternatively, for development mode with live reloading, use:

npm run dev

---

Testing the Server

1. Using the MCP Inspector

The MCP Inspector is a tool to test and inspect your MCP server. You can use it to verify that your tools and prompts are registered correctly.

Run the following command to inspect your server:

npx @modelcontextprotocol/inspector ./dist/server.js

2. Using Postman MCP

Uou can try using postman MCP client connector: Postman Client Connector

This will open an interactive interface where you can test the tools and prompts registered in your server like below.
