Stop Pasting Your Database Schema Into Every AI Prompt
Short summary
Dumping entire database schemas into AI prompts wastes tokens on every request (tens of thousands for a 240-table schema), causes hallucinations from irrelevant tables, and becomes stale after migrations. Progressive disclosure solves this: send a compact table inventory once per session, then fetch specific table schemas on demand using MCP. Infrawise automates the pattern across Postgres, MySQL, MongoDB, and DynamoDB, turning setup into a single command.
- •Full schema dumps waste tokens per request, cause hallucinations from near-duplicate tables, and drift stale after migrations
- •Progressive disclosure: query inventory once per session, then fetch only needed table schemas on demand with full join-path context
- •Infrawise tool automates via MCP for Postgres, MySQL, MongoDB, and DynamoDB—setup is npx infrawise start
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
