Connect AI Agents to Legacy Systems

Production-ready code snippets to bridge the gap between Modern AI and Enterprise Legacy.

Why AgentRetrofit?

Building agents is easy. Connecting them to a 1990s Mainframe behind a corporate firewall is hard. We provide the missing “Glue Code” to make it happen.

Battle-Tested Patterns

Stop guessing how to structure your MCP servers. Our guides provide copy-paste architectures for SAP RFC, Oracle TNS, and IBM CICS.

Docker Ready

Every guide comes with a production-ready Dockerfile. We handle the complex dependency chains (like SAP NWRFC SDKs) so you don’t have to.

Security First

Legacy systems don’t speak OAuth. We show you how to securely tunnel your agents into on-premise networks using industry-standard VPNs and Proxies.

Framework Agnostic

Whether you use CrewAI, LangGraph, AutoGen, or OpenAI Swarm, our MCP servers speak the universal language of tools.

How It Works

1. Choose Your Legacy Target

Find the system you need to unlock (e.g., SAP ECC, Oracle EBS, SOAP Web Services).

2. Copy the MCP Server

Grab our verified server.py and Dockerfile. These act as the “Translation Layer” between your modern agent and the binary legacy protocol.

3. Deploy & Connect

Deploy the container to your cloud (Railway/DigitalOcean) or local network. Your agents can now “see” the legacy system as a simple tool.
