}
}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-sql-explain-plan-visualizer": {
"name": "sql-explain-plan-visualizer",
"description": "粘贴 EXPLAIN / EXPLAIN ANALYZE 输出（PostgreSQL/MySQL/SQLite），渲染为成本树，标注估算行数与实际行数的偏差热点，并给出具体的索引建议",

}
}
}连接到 SSE 端点后，列出已开放的工具：
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}通过工具 id 调用，参数由其参数表构建：
{

"method": "tools/call",
"params": {
"name": "sql-explain-plan-visualizer",
