qualityAn implementation of the Model Context Protocol (MCP) server using Server-Sent Events (SSE) for real-time communication, providing tools for calculations and dynamic resource templates.
Provides a Bun-specific implementation of Server-Sent Events (SSE) transport for MCP servers, leveraging Bun's runtime and streaming capabilities for efficient real-time communication between server and client.
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 connectionThe 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.
This server cannot be installed
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
Enables real-time communication between client and server using Server-Sent Events (SSE) for the Model Context Protocol, specifically built for the Bun JavaScript runtime.
