Description - 

InfraResilience Agent is a Memory + Chain-of-Thought + Persona (MCP) powered LangChain agent designed for infrastructure modernization and resilience test planning.
It accepts a description of a legacy technology stack and an optional outage scenario, then generates:

Modernization Plan — technology upgrades, migration paths, best practices

Resilience Strategy — test scenarios, fault-injection drills, disaster recovery ideas

Reasoning Summary — short, human-readable rationale

Features - 

MCP: Conversation memory for multi-turn context

LangChain Agent: Tool-using agent with deterministic helpers

Toolbelt Included:

Modernization suggestions

Event decoupling (SQS/SNS)

API hardening (Gateway/WAF)

Caching strategies (Redis/ElastiCache)

Resilience drills (Oracle, Kafka, S3, Redis)

FastAPI HTTP interface for easy integration

Reusable template for agentic AI projects

Example Input:

{
  "legacy_stack": {
    "scheduler": "Autosys",
    "language": "Java 8",
    "architecture": "monolith",
    "dependencies": ["Oracle DB", "FTP transfer"],
    "use_case": "end-of-day batch risk reporting"
  },
  "outage_scenario": "Oracle DB unavailable for 30 minutes"
}
Example Output:

{
  "modernization_plan": [
    "Replace Autosys with Apache Airflow or AWS Step Functions",
    "Upgrade Java 8 → Java 17 and containerize workloads",
    "Refactor monolith into microservices and add API Gateway"
  ],
  "resilience_strategy": [
    "Test RDS Multi-AZ failover for Oracle DB",
    "Implement circuit breaker on DB calls",
    "Run DR simulation and validate RTO/RPO"
  ],
  "reasoning_summary": "Legacy stack has aging orchestration, outdated language, and tight coupling..."
}
Quick Start
Install dependencies:


pip install fastapi uvicorn langchain langchain-openai openai pydantic
Export your LLM API key:


export OPENAI_API_KEY=sk-...
Run API:

uvicorn main:app --reload --port 8000
POST to /analyze-stack with JSON payload.
