MCP网关、服务器和客户端
只要Claude Desktop不支持连接到远程服务器，您就可以使用此脚本运行从stdio到HTTP SSE（服务器发送事件）端点的网桥。
安装mcp服务器和gw
# 1. install
npm install -g mcp-server-and-gw
# 2. Or run directly with npx
npx mcp-server-and-gw http://localhost:8808/
# ...you can use environment variables too
MCP_HOST=localhost MCP_PORT=8808 npx mcp-server-and-gw将配置添加到Claude中
桥脚本是node-javasscript，但您的服务器代码可以是您使用的任何代码。
A. 模型上下文协议 网关 src/mcp-server和gw.ts 从 标准输入输出 向 HTTP SSE 运输。
## 1. Build
yarn install
yarn build
## 2. Copy the code or update the claude_desktop_config.json
## NOTE: Ensure that npx is in the PATH, or use full path like /opt/homebrew/bin/npx
echo '{
"mcpServers": {
"Claude Gateway Example": {
"command": "npx",
"args": [
"mcp-server-and-gw", "http://localhost:8808/"
]
}
}
}' > ~/Library/Application\ Support/Claude/claude_desktop_config.json
## 3. Start server so that claude can connect to it for discoverying its resources, tools, etc.
PORT=8808 node examples/server.js
## 4. Start Claude Desktop服务器和客户端示例
您还可以独立于Claude Desktop开发SSE服务器，从而获得更快的迭代。例如，运行 src/server.ts 并使用 src/client.ts 作为客户。
启动服务器，在另一个终端上启动客户端后，您将看到服务器输出。
