Add to LibreChat's docker-compose.yml: services: librechat: networks: - LibreChat environment: - MCP_SCHOOL_VACATION_URL=http://school-vacation-mcp:3000/mcp - MCP_SCHOOL_VACATION_TOKEN=${MCP_AUTH_TOKEN:-} networks: LibreChat: name: LibreChat external: true 2. Start MCP server first (creates network): cd /path/to/School_MCP docker-compose up -d 3. Start LibreChat (joins network): cd /path/to/LibreChat docker-compose up -d 4. Test connection from LibreChat: docker exec librechat curl http://school-vacation-mcp:3000/health ═══════════════════════════════════════════════════════════════════ AVAILABLE TOOLS ═══════════════════════════════════════════════════════════════════ 1. check_school_vacation - Check if a date is a school vacation - Params: date (DD/MM/YYYY), region 2. get_vacation_periods - Get all vacation periods for a region - Params: region, year (optional) 3. get_supported_regions - List all available regions - No params REGIONS SUPPORTED: - Belgium: flanders, wallonia - Netherlands: north-netherlands, middle-netherlands, south-netherlands - Luxembourg: luxembourg DATA COVERAGE: 2019-2028 ═══════════════════════════════════════════════════════════════════ FILES CREATED/MODIFIED ═══════════════════════════════════════════════════════════════════ Modified: ✓ package.json - SDK v1.21.0 ✓ src/index.ts - Server constructor fixed ✓ src/mcp-http-server.ts - Protocol version + auth ✓ docker-compose.yml - LibreChat network added ✓ README.md - LibreChat integration section Created: ✓ src/auth.ts - Authentication middleware ✓ MCP_COMPLIANCE.md - Compliance report (9.9 KB) ✓ UPGRADE_SUMMARY.md - Upgrade guide (5.4 KB) ✓ LIBRECHAT_INTEGRATION.md - Integration guide (11.4 KB) ✓ .env.example - Configuration template ═══════════════════════════════════════════════════════════════════ TESTING ═══════════════════════════════════════════════════════════════════ ✓ Build completes without errors ✓ stdio server works with MCP 2025-06-18 ✓ HTTP+MCP server responds correctly ✓ Tools list returns all 3 tools ✓ Tool execution works (check_school_vacation tested) ✓ Authentication middleware functions correctly ✓ Docker network configuration valid ═══════════════════════════════════════════════════════════════════ NEXT STEPS ═══════════════════════════════════════════════════════════════════ For LibreChat Integration: 1. Review LIBRECHAT_INTEGRATION.md for detailed steps 2. Update LibreChat's docker-compose.yml with network config 3. Configure LibreChat to use the MCP server endpoint 4. Test tools in LibreChat UI For Production Deployment: 1. Set strong MCP_AUTH_TOKEN 2. Configure HTTPS/TLS if exposing publicly 3. Review MCP_COMPLIANCE.md security section 4. Consider rate limiting for public deployments ═══════════════════════════════════════════════════════════════════ COMPLIANCE STATUS ═══════════════════════════════════════════════════════════════════ ✅ MCP Protocol Version: 2025-06-18 ✅ SDK Version: 1.21.0 ✅ JSON-RPC 2.0: Compliant ✅ Capability Negotiation: Implemented ✅ Tool Definitions: JSON Schema compliant ✅ Error Handling: Per specification ✅ Authentication: Token-based (optional) ✅ Audit Logging: Implemented ✅ Docker Network: Configured for LibreChat ⚠️ Optional (production recommendations): - Full OAuth 2.0 (currently: basic token auth) - Rate limiting (express-rate-limit) - Structured output schemas (Zod) - Input validation ═══════════════════════════════════════════════════════════════════ STATUS: COMPLETE ✓ ═══════════════════════════════════════════════════════════════════ The MCP server is fully compliant with MCP 2025-06-18 specification and ready for LibreChat integration via Docker networking.
