Architecture Overview

High-level architecture of Terry-Form MCP

Key Architectural Principles

🔒 Security First

Every component is designed with security as the primary concern. Defense in depth with multiple security layers.

📦 Modular Design

Components are loosely coupled and can be deployed independently. Easy to extend and maintain.

🚀 High Performance

Asynchronous operations, connection pooling, and intelligent caching for optimal performance.

🔄 Scalability

Horizontal scaling support with stateless components and shared state management.

🛡️ Fault Tolerance

Graceful error handling, circuit breakers, and automatic recovery mechanisms.

📊 Observable

Comprehensive logging, metrics, and tracing for full system visibility.

Component Overview

Protocol Layer

Handles MCP and HTTP communications

Request validation
Response formatting
Protocol translation

Security Layer

Enforces security policies

Authentication
Authorization
Input sanitization

Execution Engine

Manages Terraform operations

Command execution
State management
Resource isolation

Integration Layer

External service connections

GitHub API
Cloud providers
Terraform Cloud

Deployment Architectures

Single Instance

Best for development and small teams.
