PlanetScale

PlanetScale gives Claude live, authenticated access to your PlanetScale accounts so you can browse organizations, databases, and branches without leaving your editor or chat. You can list branches, inspect branch status, and fetch connection details. It maps your schema objects—tables, columns, indexes—so you can ask specific questions about structure and relationships.

Run SQL queries against a selected branch and return results as JSON or tabular text. The plugin reads query execution info and pulls Insights metrics so you can check slow queries, error rates, and query distribution. It also exposes account and organization metadata so you can verify permissions and billing context while debugging.

The tool supports interactive workflows: run a query, review results, then request a follow-up optimization that references exact slow queries from Insights. It lets you switch branches, re-run tests, and compare schemas across branches without copying connection strings or hopping into a separate console.

For example, when a staging endpoint shows errors you can inspect the failing query, pull the Insight that highlights its latency, and try an optimized query all inside Claude. That saves time and prevents context switching between your chat, a SQL client, and the PlanetScale console during an incident response or schema review.
