What it does

mcpWhiz helps you build and test MCP servers right in your browser. Upload your OpenAPI, Postman, GraphQL, HAR, or WSDL/SOAP specs and instantly see generated code in Python or TypeScript inside a built-in code editor. Edit, explore, and run test servers directly in the browser to see how your MCP setup behaves—no setup or deployment required, just fast, hands-on experimentation.

Convert Swagger/OpenAPI, Postman Collections, and GraphQL APIs into Model Context Protocol (MCP) servers instantly. Free, open-source MCP server builder with TypeScript & Python code generation.

Our intelligent code generator creates clean, maintainable TypeScript/Python code that follows MCP best practices. No more boilerplate - just focus on your server's functionality. import express from "express"; import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js"; import { StreamableHTTPServerTransport } from "@modelcontextprotocol/sdk/server/streamableHttp.js"; const app = express(); const server = new McpServer({ name: "My MCP Server", version: "1.0.0" }); server.registerTool("calculate", { title: "Calculator", description: "Perform calculations" }, async ({ expression }) => { // Generated tool logic }); Ready to Build Your MCP Server?

  MCP Playground is a Postman-style tool for MCP — inspect servers, execute tools live, test your client, all from the browser. Four things in one place: 1. Free hosted MCP servers — four public test servers anyone can point their client at: Echo (connectivity), Auth (Bearer token flow), Error (error handling), Complex (multi-tool schemas).No sign-up, just use the URL. 2. Server inspector — paste any remote MCP server URL, see all its tools/resources/prompts, execute them live, inspect the full JSON-RPC log. HTTP, SSE, and WebSocket all supported. 3. Registry — 10,000+ servers…

  Hyperbrowser MCP Server – Connect AI agents to the web through browsers2025 · github.com · ▲63

  Hi HN! Excited to share our MCP Server at Hyperbrowser - something we’ve been working on for a few days. We think it’s a pretty neat way to connect LLMs and IDEs like Cursor / Windsurf to the internet. Our MCP server exposes seven tools for data collection and browsing: 1. `scrape_webpage` - Extract formatted (markdown, screenshot etc) content from any webpage 2. `crawl_webpages` - Navigate through multiple linked pages and extract LLM-friendly formatted content 3. `extract_structured_data` - Convert messy HTML into structured JSON 4. `search_with_bing` - Query the web and get results…

  We packaged an MCP server inside Chromium2025 · github.com · ▲46

  Hey HN, we just shipped a browser with an inbuilt MCP server! We're a YC startup (S24) building BrowserOS — an open‑source Chromium fork. We're a privacy‑first alternative to the new wave of AI browsers like Dia, Perplexity Comet. Since launching ~3 months ago, the #1 request has been to expose our browser as an MCP server. -- Google beat us to launch with chrome-devtools-mcp (solid product btw), which lets you build/debug web apps by connecting Chrome to coding assistants. But we wanted to take this a step further: we packaged the MCP server directly into our browser binary. That gives…
