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
| Tool | What it does |
|---|---|
query |
Execute SQL (SELECT, PRAGMA, EXPLAIN, WITH). Returns results as a table. |
schema |
Full schema: all tables with columns, types, and row counts |
table_info |
Detailed info for a single table: columns, constraints, row count |
explain |
Run EXPLAIN QUERY PLAN for query optimization |
list_databases |
List .db, .sqlite, .sqlite3 files in a directory |

Key Patterns
- Read-only by default — only SELECT, PRAGMA, EXPLAIN, and WITH are allowed
- Pass
readonly: falsein tool args to enable INSERT, UPDATE, DELETE schemareturns everything at once — use it first to understand the databasequeryreturns 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
