MCP 集成

将此工具加入你的 Model Context Protocol 服务，让 AI 智能体可以列出并调用它。

服务配置

将以下内容加入你的 MCP 客户端配置：

mcp.json

{
  "mcpServers": {
    "elysiatools-color-expander": {
      "name": "color-expander",
      "description": "将3位HEX代码扩展为6位代码（如#FFF到#FFFFFF）",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=color-expander",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

列出可用工具

连接到 SSE 端点后，列出已开放的工具：

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

调用此工具

通过工具 id 调用，参数由其参数表构建：

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "color-expander",
    "arguments": {
  "colors": "Enter HEX colors, one per line:\n#FFF\n#000\n#F00\n#0F0\n#00F\n#FF0\n#F0F\n#0FF\nFFFFFF\n000000",
  "format": "uppercase",
  "includeAlreadyExpanded": false
}
  }
}

可用逗号分隔的 toolId 在一个会话中串联多个工具，例如 /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp（最多 20 个）。
