OpenAPI to MCP Server Converter
A tool for automatically converting OpenAPI specifications into Model Context Protocol (MCP) server instance
Features
- 🚀 Automated Conversion: Auto-parses OpenAPI 3.0 specifications
- 🛠 Type Safety: TypeScript-based strong type validation
- 🔄 Request Proxy: Automatically handles tool call parameter mapping
Quick Start
Prerequisites
- Node.js 18+
- TypeScript 5.x
Basic Usage
Install the package:
npm install openapi-mcp-converter
Run a local stdio MCP server:
import { OpenApiMCPSeverConverter } from "openapi-mcp-converter";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import fs from "fs";
const openApiDoc = JSON.parse(fs.readFileSync("./openapi.json"));
const converter = new OpenApiMCPSeverConverter(openApiDoc);
const server = converter.getServer();
// Start MCP service
async function runServer() {
const transport = new StdioServerTransport();
await server.connect(transport);
console.log("GitHub MCP Server running on stdio");
}
runServer().catch((error) => {
console.error("Fatal error in main():", error);
process.exit(1);
});
