Lets an LLM explore a cryptic legacy ERP schema in plain language through a semantic layer (table listing, column descriptions, published dictionary) and run single read-only SELECT queries that return capped results. Enforces safety at the database engine level: only reads are authorized, sensitive columns are masked to NULL, queries are aborted after a few seconds, and every call is written to an append-only audit log.

Enables an LLM to answer questions about Colombian public procurement from the SECOP II electronic contracts open dataset on datos.gov.co, with typed queries that are built into SoQL by the server. A column allowlist and local entity directory keep personal-data fields unreachable and resolve institution names to NITs, so users get aggregate contract figures without writing queries themselves.
