Why Cursor Needs Explicit SQLite Schema Context
Cursor is the AI-first code editor. Like all LLM-powered coding tools, it has no native awareness of your database. Without explicit schema context, it will hallucinate JOIN paths, reference non-existent columns, query sensitive fields, and waste thousands of tokens per prompt.
Schemap solves this by extracting your live SQLite schema and compiling it into .cursor/rules/schemap.mdc — a file Cursor reads automatically from your project root.
Quickstart: SQLite + Cursor in 3 Steps
Step 1 — Install Schemap
pipx install schemap-tool
# or: uv tool install schemap-toolStep 2 — Connect to SQLite
schemap quickstart
# Enter: sqlite:///path/to/database.dbStep 3 — Generate Cursor rules
schemap agents --targets cursor
# Wrote .cursor/rules/schemap.mdc with safety guardrails in 2msWhat Schemap Injects into .mdc rules
- Table Map — every SQLite table with column types
- Foreign Key Graph — explicit JOIN relationships, no guessing
- Centrality Scores — most-connected tables highlighted
- [SAFETY] Guardrails — blocks sensitive column access and audit table mutation
- Candidate FK Detection — inferred missing relationships from naming patterns
Token Cost Savings on SQLite Schemas
Raw SQLite DDL dumps run 15,000–80,000 tokens. Schemap reduces that by 89%%. Run schemap benchmark --cost to calculate your exact monthly savings.
Keep Context in Sync Automatically
schemap hook install
# Auto-regenerates .cursor/rules/schemap.mdc on every migration commitFrequently Asked Questions
How do I give Cursor SQLite database context?
Install Schemap with pipx install schemap-tool, connect to your SQLite database (sqlite:///path/to/database.db), then run schemap agents --targets cursor to auto-generate .cursor/rules/schemap.mdc with full schema context, foreign key maps, and anti-hallucination safety rules.
Does Schemap support SQLite with Cursor?
Yes. Schemap fully supports SQLite (the most widely deployed SQL database engine) and generates native Cursor rules that Cursor reads automatically from your project directory.
What makes Schemap better than manually writing .mdc rules for SQLite?
Manual schema files go stale instantly. Schemap runs in sub-3ms, auto-infers foreign keys, injects SAFETY guardrails, and compresses your SQLite schema by up to 89%% so Cursor always has accurate context.
