PlanetScale database skills

Pick the one engine skill that matches the database in front of you and follow it. Read only that skill; the engines disagree on enough details that mixing their guidance produces wrong advice.

Pick an engine

Database Skill
MySQL-compatible, unsharded database-mysql
PlanetScale Postgres database-postgres
Vitess (sharded MySQL, keyspaces, VSchema) database-vitess
Neki (sharded Postgres) database-neki

If you do not know which engine backs the database, determine it with the PlanetScale MCP server before choosing — do not infer it from the connection string, ORM, or repository conventions.
