Connect

Add this to your MCP client config (Cursor, Claude Desktop, VS Code, Cline and others that support remote servers):

{
  "mcpServers": {
    "tandiu": {
      "url": "https://www.tandiu.cn/mcp"
    }
  }
}

Clients that only support stdio can use mcp-remote:

{
  "mcpServers": {
    "tandiu": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://www.tandiu.cn/mcp"]
    }
  }
}

Quick test with curl:

curl -s https://www.tandiu.cn/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
