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.
