About Bun MCP Sse Transport
Bun MCP Sse Transport is an MCP server published by tigranbs in the Developer Tools category: bun Server Transport implementation for MCP - MCP SSE. It has been installed 0 times through Conduid.
The repository has 12 stars and 6 forks, with the last commit a year ago. Six months or more without a commit doesn't mean the server is broken, but check the open issues (0) before depending on it in production.
Install
npx bun-mcp-sse-transportThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

README
bun-mcp-sse-transport
A Server-Sent Events (SSE) transport implementation for the Model Context Protocol (MCP) using Bun.
Overview
This package provides a Bun-specific implementation of SSE transport for MCP servers. It enables real-time, one-way communication from server to client using the SSE protocol, with client-to-server communication handled via HTTP POST requests.
Key Features
- Built specifically for Bun runtime
- Implements the MCP transport interface
- Manages SSE connections with proper headers
- Handles incoming JSON-RPC messages
- Simple integration with Bun.serve
Quick Usage
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { BunSSEServerTransport } from "bun-mcp-sse-transport";
// Create SSE transport
const transport = new BunSSEServerTransport("/messages");
// Connect to MCP server
const server = new McpServer({ name: "MyServer", version: "1.0.0" });
server.connect(transport);
// Set up Bun HTTP server
Bun.serve({
port: 3000,
routes: {
"/sse": () => transport.createResponse(),
"/messages": (req) => transport.handlePostMessage(req)
}
});
How It Works
- When a client connects to
/sse, the server creates an SSE connection - The server sends the endpoint URL where the client should POST messages
- The client sends JSON-RPC messages to the endpoint URL
- The server receives these messages and passes them to the MCP server
- The MCP server processes the messages and sends responses via the SSE connection
This implementation follows the MCP standard while leveraging Bun's streaming capabilities for efficient real-time communication.
