}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。
将以下内容加入你的 MCP 客户端配置：
{
"mcpServers": {
"elysiatools-color-vision-accessibility-checker": {
"name": "color-vision-accessibility-checker",
"description": "计算 WCAG 对比度，模拟主要色觉缺陷，并可对 UI 截图中的低对比区域做标记。",

}
}
}连接到 SSE 端点后，列出已开放的工具：
{
"jsonrpc": "2.0",
"id": 1,
