MCPStudio: The Postman For Model Context Protocol MCP Server

Postman for MCP servers

The short version

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.

• Server Management — — Create, configure, connect to, and monitor MCP servers with status tracking (connected / disconnected / error)
• Tool Discovery & Execution — — Auto-discover tools exposed by MCP servers, fill parameters via dynamic forms, and view formatted responses
• Tools Library — — Browse all tools across connected servers with search and server filtering
• Execution Dashboard — — Real-time metrics with Recharts (timing, tool distribution, success/error rates) and persistent history via IndexedDB
• Execution History — — Server-side persistent execution log with expandable rows, pagination, and clear
• Visual Pipeline Builder — — Drag-and-drop React Flow canvas to chain MCP tools into DAG pipelines with auto-layout and frontend execution engine

What it needs from you

• Python 3.10+ - Node.js 16+ - MongoDB (optional — falls back to in-memory mock when unavailable) - UV package manager (recommended)
