MCP SSE demo

What is MCP SSE Demo?

MCP SSE Demo is a reproducible demonstration that showcases the limitations of an MCP SSE server when using the Bun runtime compared to Node.js.

How to use MCP SSE Demo?

To use MCP SSE Demo, follow these steps:

1. Install dependencies using Bun: bun install.
2. Run the MCP inspector with npm run inspect.
3. Open the inspector at http://localhost:5173.
4. Select SSE as the transport and enter http://localhost:3500/sse as the URL.
5. Open the dev tools network tab to inspect traffic.
6. In another terminal, run the server using Bun: npm run start:bun.
7. Connect to the server using the inspector and observe the logs.
8. Kill the Bun server and run the server using Node.js: npm run start:node.
9. Connect again to see the successful SSE connection.
