Key outcomes

Exposed database CRUD operations through MCP-compatible tools.
Focused on reliable query execution so LLM-driven workflows could interact with live relational data.
Extended Umar's AI engineering profile beyond model usage into protocol and tooling design.

The value of this project was its practicality. Instead of treating LLMs as isolated chat systems, it connected them to structured operational data through a protocol layer that can support repeatable workflows.

It demonstrates experience with the emerging MCP ecosystem and with the engineering discipline required when model-facing tools are allowed to touch real databases.
