1. Add the server

Run in your terminal

gemini mcp add --transport http planetscale https://mcp.pscale.dev/mcp/planetscale

2. Sign in

Run /mcp auth <name> inside Gemini CLI to sign in to an OAuth server. PlanetScale is hosted by PlanetScale, so there is nothing to install or keep updated.

3. Try it

Ask Gemini CLI 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.

· In settings.json, streamable HTTP servers use httpUrl, SSE servers use url, local servers use command.
· includeTools and excludeTools limit which tools the model sees.
