hono-mcp-server-sse-transport

About

This project provides a transport for Hono application that needs to connect to MCP Server. An official TypeScript SDK is designed to be used with express. If you try and follow their instructions but change express with hono, you will find that it's not going to work. Even if you set HttpBinding as an env (see an example from @hono/node-server), it still doesn't work as some headers are being added to a response after it's sent.

This implementation is inspired by the following pull request

You can use this transport until there is a proper support for Hono in the official SDK.
