PlanetScale MCP Server (Official)
Official PlanetScale MCP server (integrated in the PlanetScale CLI) enabling AI agents to interact with PlanetScale databases — querying data, managing database branches, running schema migrations, and monitoring database status.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Service tokens with fine-grained per-database permissions. HTTPS enforced. SOC 2 Type II certified. Good overall security posture.
⚡ Reliability
Best When
An agent needs to query or manage a PlanetScale MySQL database, particularly leveraging PlanetScale's branching and schema change workflow.
Avoid When
You're using PostgreSQL, MongoDB, or other non-MySQL databases.
Use Cases
- • Querying PlanetScale databases from agent workflows
- • Managing database branches for schema change workflows
- • Running and monitoring schema migrations via deploy requests
- • Checking database performance insights and slow query analysis
- • Automated schema drift detection between branches
Not For
- • Non-MySQL/PlanetScale databases
- • High-frequency real-time transactions (PlanetScale is not a Redis replacement)
- • Teams not using PlanetScale's serverless MySQL
Interface
Authentication
Service tokens with fine-grained permissions (read vs write vs admin per database). OAuth for user-level auth. Service tokens recommended for agent use.
Pricing
Generous free tier. Row read pricing model — agents making many queries should monitor usage.
Agent Metadata
Known Gotchas
- ⚠ PlanetScale requires explicit branch selection — agents must specify the correct branch
- ⚠ Schema changes must go through deploy requests — DDL statements blocked on production branches
- ⚠ Row read billing means expensive agent queries (full table scans) accrue real costs
- ⚠ PlanetScale's sharding via Vitess means some MySQL queries not supported (foreign keys)
- ⚠ Database branches are ephemeral — agents should not hardcode branch names
