In this article we explain how to orchestrate Model Context Protocol MCP servers in a real TypeScript application using LlamaIndex.TS as the coordination engine. We use the Azure AI Travel Agents project as a reference to illustrate best practices in security, scalability and maintenance, and offer recommendations applicable to custom application and custom software projects.
Summary In modern artificial intelligence and AI agent environments, orchestrating MCP instances allows managing context, memory and sessions of multiple distributed models. Using LlamaIndex.TS in TypeScript provides an abstraction layer for indexing, context retrieval and routing between MCP servers, which facilitates creating robust solutions for enterprise AI and AI agents that integrate enterprise data and aws and azure cloud services.
Requirements and preparation Before starting you will need a TypeScript project, access to a model provider and storage for indexes and vectors. In practice, it is advisable to integrate aws and azure cloud services according to your stack. Ensure you have cybersecurity controls, managed keys and separate development, staging and production environments. If you work with enterprise data, add privacy policies and business intelligence services to enrich indexes and improve model responses.
Recommended architecture 1 Central TypeScript orchestrator that uses LlamaIndex.TS to build and query indexes 2 One or more MCP servers that host models and manage context per session 3 Vector and object storage in a managed service or an optimized database engine 4 Authentication and auditing layer for cybersecurity 5 Observability with metrics, traces and logs to scale on demand
Basic workflow 1 Ingestion of documents and enterprise data from internal sources and business intelligence services 2 Creation of indexes and embeddings with LlamaIndex.TS 3 Orchestrator queries indexes to retrieve relevant context 4 Orchestrator routes requests to the appropriate MCP server 5 The MCP server maintains session context and calls the final model 6 Result returned to the client with traceability and metrics
Practical implementation with TypeScript and LlamaIndex.TS Step 1 Configure LlamaIndex.TS for your TypeScript project. Step 2 Define adapters for your data sources and for the embedding store. Step 3 Implement an orchestration layer that exposes secure endpoints that validate and enrich requests with additional context. Step 4 Design an MCP server registry that allows discovering available instances and their capabilities. Step 5 Add routing logic based on load, latency and model specialization.
Code tips and patterns Use strong typing with TypeScript to define contracts between the orchestrator and MCP servers. Use dependency injection to allow testing and component changes. Implement retry and circuit breaker patterns for fault tolerance. Keep context extractors and loaders decoupled to facilitate maintenance. Centralize security configuration and usage limits to facilitate compliance and auditing.
Security and cybersecurity Protect communications between the orchestrator and MCP with TLS and mutual authentication if possible. Manage credentials with AWS or Azure secret services. Apply access controls and roles to limit who can create or query indexes. Log access and usage events for anomaly detection. Integrate cybersecurity testing into the development cycle to reduce risks.
Scalability and deployment Containerize components and use orchestrators like Kubernetes to scale MCP servers and indexing services. On Azure consider AKS and on AWS EKS or serverless options when appropriate. Enable auto-scaling based on latency and CPU usage metrics. For cost and performance, separate index storage from the model execution layer. For variable workloads, combine on-demand instances with reserved or spot instances.
Observability and maintenance Implement key metrics such as query latency, index hit rate, context memory usage and errors per endpoint. Centralize logs and traces to quickly diagnose issues. Schedule index maintenance and retraining strategies when data changes. Maintain a CI CD pipeline that allows updating components without interrupting active sessions.
Integration with enterprise services and BI Connect your orchestrator to ETL pipelines and business intelligence services so indexes reflect updated data. Use Power BI to visualize usage and performance metrics, and to provide intelligence dashboards that complement AI agent responses. This is especially valuable in custom application and custom software solutions where customer data is the main asset.
Typical use cases Support agents that maintain customer context per session Commercial AI agents that combine CRM and financial data for personalized recommendations Internal search and assistance solutions for employees that integrate corporate policies and documentation Custom applications that require traceable responses and regulatory compliance
Best practices for real projects Design for privacy and security from the start Define SLAs and scaling policies Monitor and automate index updates Keep infrastructure as modular as possible to facilitate migrations between aws and azure cloud services Consider data sovereignty and regulatory requirements
