Hey Product Hunt 👋 While working with Model Context Protocol (MCP) servers, we kept running into the same problem: testing them was painful. Most of the time it involved manually crafting JSON payloads, sending curl requests, tweaking headers, and trying to debug responses without much visibility. So we built ProtoMCP. It’s a browser-based playground that makes it much easier to explore and test MCP servers. With ProtoMCP you can: • Connect to any MCP server • Automatically discover tools, prompts, and resources • Run tools using generated input forms • Inspect JSON-RPC requests and responses in real time • Debug MCP integrations visually
