PlanetScale MCP Server Tools

This repository contains tool implementations that are part of the [PlanetScale MCP server][ps-mcp].

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.

  • Hosted server overview: [PlanetScale MCP docs][ps-mcp]
  • PlanetScale API OpenAPI spec: [OpenAPI spec docs][ps-openapi]

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][mcp-inspector] so you can interactively test tool behavior during development.
