MCP Server Patterns: Four Architectural Blueprints
Four distinct MCP server patterns have emerged from enterprise deployments, each optimized for a different type of business capability.
The Four MCP Server Patterns
Not all MCP servers serve the same purpose. Four distinct patterns have emerged from enterprise MCP deployments, each optimized for a different type of business capability.
Base Application Server
Exposes core business actions for a single enterprise application. The foundational pattern.
Process Composite Server
Coordinates multi-step business processes across multiple systems through a single MCP interface.
Orchestration-Federated Server
Federates across multiple MCP servers, presenting a unified tool interface to agents.
Data and Insights Server
Surfaces business intelligence and analytics data through governed MCP tools.
How to Choose
| Pattern | Use When | Governance Complexity |
|---|---|---|
| Base Application | Exposing actions for one enterprise app | Low |
| Process Composite | Orchestrating multi-step processes across apps | Medium |
| Orchestration-Federated | Unifying many MCP servers behind one interface | High |
| Data and Insights | Providing analytics and reporting data to agents | Medium |
