lonexreb/MCPstudio
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.
See repository
Setup steps are in the repository README.
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
Tool Execution Arena — Side-by-side resizable panels for comparing tool executions with JSON diff and timing comparison
MCP Server Discovery — Search npm and GitHub registries for MCP-compatible servers with source filtering and install commands
Resources Browser — Discover and browse data sources exposed by connected MCP servers
Prompt Templates — Create, edit, tag, and manage reusable prompt patterns with {{variable}} placeholders (stored in IndexedDB)
