What is bun-mcp-sse-transport?
A Server-Sent Events (SSE) transport implementation for the Model Context Protocol (MCP) built specifically for the Bun runtime. It enables real-time, one-way communication from server to client using SSE, with client-to-server communication handled via HTTP POST requests. Designed for developers building MCP servers on Bun.
How to use bun-mcp-sse-transport?
Install the package and import the BunSSEServerTransport class. Create an MCP server with @modelcontextprotocol/sdk, connect it to the transport, then set up a Bun HTTP server with routes: /sse returns the SSE response and /messages handles incoming POST requests.
Key features of bun-mcp-sse-transport
- Built specifically for the Bun runtime
- Implements the MCP transport interface
- Manages SSE connections with proper headers
- Handles incoming JSON-RPC messages
- Simple integration with Bun.serve
- Real-time, one-way server-to-client communication via SSE

FAQ from bun-mcp-sse-transport
What runtime does bun-mcp-sse-transport require?
It requires Bun.
How does the client communicate back to the server?
The client sends JSON-RPC messages via HTTP POST requests to an endpoint URL provided in the initial SSE connection.
What endpoints must a server expose?
The example shows /sse for establishing the SSE connection and /messages for receiving client POST requests.
What protocol does it implement?
It implements the Model Context Protocol (MCP) transport interface and handles JSON-RPC messages.
Does it support the standard MCP flow?
Yes. The server creates an SSE connection, sends the endpoint URL, receives JSON-RPC messages via HTTP POST, and sends responses back over the SSE connection.
