System Integration: MCP and the Connected Enterprise
REST, event-driven patterns, and Model Context Protocol connectors kept data flowing between ERP, CRM, and custom apps in 2025.
Most organisations in 2025 did not suffer from a lack of software — they suffered from disconnected software. Integration projects turned isolated systems into a coherent operational picture: orders, inventory, finance, and customer records updating without manual re-entry.
Integration styles
REST APIs remained the workhorse for synchronous calls. GraphQL gained traction where mobile and web clients needed flexible queries without over-fetching. For high-volume or decoupled flows, message brokers such as Azure Service Bus, RabbitMQ, or Kafka carried events between services with retry and dead-letter handling.
MCP and agentic connectors
The Model Context Protocol (MCP) emerged as a standard way for AI agents to call approved enterprise tools safely. Rather than brittle screen scraping, MCP servers exposed curated read and write operations with audit logs. Platforms like MuleSoft, Boomi, or Azure Logic Apps still accelerated standard connectors, while custom middleware handled domain-specific rules no template could capture.
Quality and governance
Versioned API contracts, OpenAPI documentation, and sandbox environments reduced breakage when vendors upgraded. Monitoring integration latency and error rates was as important as monitoring application uptime. Human-in-the-loop gates protected financial and HR integrations touched by agentic workflows.
