School Vacation MCP Server

═══════════════════════════════════════════════════════════════ SSE TRANSPORT SUPPORT ADDED ✓ LibreChat Connection Fixed ═══════════════════════════════════════════════════════════════ PROBLEM IDENTIFIED: ------------------- LibreChat was trying to connect via SSE transport at: http://school-vacation-mcp:3000/sse But the server only had HTTP JSON-RPC endpoint at: http://school-vacation-mcp:3000/mcp This caused Zod validation errors because LibreChat expected SSE responses but received HTTP responses. SOLUTION IMPLEMENTED: ---------------------- ✓ Created new SSE-compatible server: src/mcp-sse-server.ts ✓ Added SSE transport using @modelcontextprotocol/sdk/server/sse ✓ Implements GET /sse endpoint for SSE connections ✓ Implements POST /message endpoint for client messages ✓ Updated package.json with start:sse script ✓ Updated Dockerfile to use start:sse by default ✓ Updated LIBRECHAT_INTEGRATION.md with SSE details TRANSPORT OPTIONS: ------------------ The server now supports BOTH transports: 1. SSE Transport (LibreChat default) Endpoint: http://school-vacation-mcp:3000/sse Use: LibreChat and other SSE clients 2. HTTP JSON-RPC Transport Endpoint: http://school-vacation-mcp:3000/mcp Use: Custom HTTP clients LIBRECHAT CONFIGURATION: ------------------------ LibreChat should connect to: http://school-vacation-mcp:3000/sse Example config: ```yaml mcp: servers: school-vacation: url: http://school-vacation-mcp:3000/sse transport: sse ``` DEPLOYMENT: ----------- The Docker container now starts the SSE server by default: docker-compose build docker-compose up -d Server will be accessible at: - SSE: http://school-vacation-mcp:3000/sse (for LibreChat) - Health: http://localhost:3000/health TESTING: -------- ✓ Build completes without errors ✓ SSE server starts successfully ✓ Health check responds correctly ✓ Ready for LibreChat connection FILES MODIFIED: --------------- • src/mcp-sse-server.ts (NEW) - SSE transport server • package.json - Added start:sse script • Dockerfile - Changed CMD to start:sse • LIBRECHAT_INTEGRATION.md - Added SSE documentation NEXT STEPS: ----------- 1. Rebuild Docker image: docker-compose build 2. Restart container: docker-compose up -d 3. LibreChat should now connect successfully 4. Check LibreChat logs for connection confirmation ═══════════════════════════════════════════════════════════════ STATUS: SSE TRANSPORT READY ✓ ═══════════════════════════════════════════════════════════════
