Which integrations are available for this server?

Used as the web framework for implementing the MCP server with SSE capabilities as shown in the HTTP headers References GitHub repositories for code examples, including vanilla SSE implementation and MCP Inspector Provides the runtime environment for the MCP server implementation with examples given in the document Demonstrates packet capture and analysis for examining MCP protocol traffic and Server-Sent Events (SSE) communication

How do I use SSE MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@SSE MCP Server get the top 10 stories from Hacker News" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

SSE MCP

HTTP+SSE 将逐步被替换为 Streamable HTTP

Replace HTTP+SSE with new "Streamable HTTP" transport

现状

本地通过stdio运行MCP不安全
- 恶意MCP可以伪装成正常工具被LLM调用
- 敏感数据泄漏
- 安装不方便(npx/uvx/docker)
MCP服务器托管开始流行
- 经过筛选
- 身份认证
- 阿里云百练/腾讯云/Zapier
- HTTP+SSE / Streamable HTTP

ChatGPT: 使用event来声明自定义事件
KIMI: 全部用默认message事件，在JSON里面的event字段声明自定义事件
都没有定义ID
- 无需短线重连
- 有序发送数据，一次性消费
