MCPStudio is a web platform for creating, testing, managing, and discovering Model Context Protocol (MCP) servers. Like Postman for APIs, MCPStudio provides a visual interface that abstracts away protocol complexity — letting you connect to MCP servers, discover tools, execute them with parameters, and inspect results, all from the browser.
