SQLite Query via MCP

Use this skill when you need to query SQLite databases, inspect schemas, or optimize queries. Read-only by default for safety.

Available Tools

Workflow

1. list_databases to find .db files in the project
2. schema to understand the full database structure
3. table_info for detailed column info on specific tables
4. query to run SELECT queries and inspect data
5. explain to optimize slow queries

Key Patterns

• Read-only by default — only SELECT, PRAGMA, EXPLAIN, and WITH are allowed
• Pass readonly: false in tool args to enable INSERT, UPDATE, DELETE
• schema returns everything at once — use it first to understand the database
• query returns tabular results — ideal for exploration and debugging
• Database path is passed per-tool call, not globally configured

Safety

• Read-only mode is on by default — no accidental mutations
• Confirm with the user before enabling write mode (readonly: false)
• Large result sets are truncated — use LIMIT in queries for efficiency
