From e2994f33e96c394cdcea57dc2157ce72f2bbd674 Mon Sep 17 00:00:00 2001 From: EladAriel Date: Tue, 26 Aug 2025 10:13:23 +0300 Subject: [PATCH] feat: Add comprehensive multi-server support to MCP Inspector MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit introduces comprehensive multi-server support to the MCP Inspector, transforming it from a single-server debugging tool into a powerful multi-server management platform. ## Key Features �️ **Server-Side Architecture** - Multi-Server API: RESTful endpoints for server management, connection control, and MCP request proxying - Real-Time Event Streaming: Server-Sent Events for live status updates and notifications across all servers - Connection Management: Independent connection lifecycle management for each server - Centralized Logging: Synchronized logging level management across all connected servers - Transport Flexibility: Support for both STDIO and HTTP transport types in multi-server configurations � **Client-Side Interface** - Unified Dashboard: Tabbed interface for managing multiple servers with real-time status monitoring - Server Management: Complete CRUD operations for server configurations with validation - Error Aggregation: Sophisticated error handling with console error interception and deduplication - State Persistence: LocalStorage-based configuration management with cache invalidation - Mode Switching: Seamless toggle between single-server and multi-server modes ## Technical Implementation ### Backend () - ServerManager: Handles CRUD operations for server configurations with Zod validation - ConnectionManager: Manages connection lifecycle, status tracking, and transport creation - EventStreamService: Provides real-time updates via Server-Sent Events - MCP Proxy: Unified API for communicating with individual servers ### Frontend () - useMultiServer Hook: 600+ lines of comprehensive state management with real-time updates - Error Management: Sophisticated error aggregation with console interception - Request Optimization: Deduplication and batching for improved performance - History Management: Centralized notification and interaction tracking ## Benefits - Enhanced Developer Productivity: Manage multiple servers from a single interface - Improved Debugging Capabilities: Compare and analyze multiple servers simultaneously - Scalable Architecture: Support for growing MCP ecosystems - Better Error Tracking: Centralized error aggregation and monitoring - Streamlined Workflows: Reduced context switching and configuration overhead ## Backward Compatibility Full backward compatibility maintained with existing single-server endpoints and workflows. ## Testing - 40+ unit tests covering all services and utilities - Component tests and integration tests - Complete endpoint testing with .http files - Edge case and failure scenario testing This PR is submitted by Elad Ariel on behalf of the SAP AI Guild (IL). --- README.md | 38 + client/MULTISERVER_README.md | 275 ++++ client/e2e/test-results/.last-run.json | 4 + client/jest.config.cjs | 8 + client/package.json | 1 + client/src/App.tsx | 493 +++++--
