1. Add the server

Run in your terminal

codex mcp add planetscale --url https://mcp.pscale.dev/mcp/planetscale

2. Sign in

Run codex mcp login <name> to complete OAuth for a remote server. PlanetScale is hosted by PlanetScale, so there is nothing to install or keep updated.

3. Try it

Ask Codex for something PlanetScale can do. Inspect PlanetScale databases, branches, schema and query insights, and run SQL. Approve the first tool call and check the result before allowing write actions automatically.

· Each server is a [mcp_servers.<name>] table in config.toml.
· Use enabled_tools or disabled_tools to keep the tool list short.
