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-grayscale-converter": {
"name": "color-grayscale-converter",
"description": "将颜色转换为灰度，支持多种转换方法和强度控制",
"baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=color-grayscale-converter",
"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-grayscale-converter",
"arguments": {
"baseColor": "#FF5733",
"conversionMethod": "luminosity",
"intensity": 100,
"singleChannel": "green",
"customWeights": "{\n \"red\": 30,\n \"green\": 59,\n \"blue\": 11\n}",
"preserveLuminance": true,
"batchColors": "#FF0000, #00FF00, #0000FF",
"includeOriginal": true,
"showComparison": true
}
}
}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）。
