PlanetScale MCP Server Tools

This repository contains tool implementations that are part of the PlanetScale MCP server.

The full hosted MCP server includes additional tools that are generated from the PlanetScale API OpenAPI spec, not every production tool lives in this repository.

Project scope

This repo is focused on:

• MCP tools we maintain directly in TypeScript

• shared helper code used by those tools

• local development and validation of the open-source portions

Some MCP functionality is intentionally not duplicated here because it is generated from the API spec and maintained in that generation pipeline.

Quick start

Install dependencies:

pnpm install

Build a deployment zip:

pnpm build

Push to Gram:

pnpm push

Testing locally

Run a local MCP server over stdio with inspector support:

pnpm dev

This launches MCP Inspector so you can interactively test tool behavior during development.
