Openapi2mcptools

🚀 OpenAPI 规范 => MCP（模型上下文协议）工具转换器

🔧 这是一个实用库，可将 OpenAPI 规范转换为 MCP 工具。 🚀 借助它能基于 OpenAPI 规范快速开发 MCP 服务器。

🚀 快速开始

💻 使用示例

基础用法

import { Server } from '@modelcontextprotocol/sdk/server/index.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
import {
  CallToolRequestSchema,
  ListToolsRequestSchema,
} from '@modelcontextprotocol/sdk/types.js';
import { Converter } from 'openapi2mcptools';

const converter = new Converter({
  baseURL, // 可选
  httpClient // 可选
});
await converter.load({
  // 规范内容
});
const tools = converter.getToolsList();
const toolCaller = converter.getToolsCaller();

const server = new Server(
  {
    name: 'mcp-server-openapi',
    version: '1.0.0',
  },
  {
    capabilities: {
      tools: {},
    },
  },
);

// 定义可用工具
server.setRequestHandler(ListToolsRequestSchema, async () => {
  return {
    tools,
  };
});

// 处理工具执行
server.setRequestHandler(CallToolRequestSchema, async (request) => {
  return await toolCaller(request);
});

const transport = new StdioServerTransport();
await server.connect(transport);

高级用法

自定义客户端

设置 baseURL，headers 等用于 HTTP 客户端。

export type RequestConfig = {
  url?: string;
  method?: string;
  headers?: any;
  params?: any;
  data?: any;
}

export interface HTTPClient {
  request: (requestConfig: RequestConfig) => Promise<{ data: any }>;
}

示例：

import axios from axios;
import { Converter } from 'openapi2mcptools';

const converter = new Converter({
  httpClient: axios
});
