Optimizes REST API calls for AI agents by returning compact schemas instead of full responses, allowing agents to fetch only needed fields via jq masks, reducing token consumption by up to 50x.

Enables AI agents to add, edit and remove their own PostgreSQL and MySQL connections at runtime, stored in a per-project or global file that is hot-reloaded on every tool call. Connections can run through SSH tunnels with TLS verification, and readonly sessions plus per-call timeouts and capped result sizes keep agent queries safe.
