Stop Pasting Your Database Schema Into Every AI Prompt

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?
