Overview

AI-generated overview

Hosted PlanetScale MCP server that lets an assistant inspect databases, branches and schema, review query insights, and run SQL.

What you can do
  • Connect to PlanetScale databases and browse their branches and schema
  • Review query insights for database performance
  • Execute SQL against PlanetScale databases
  • Use additional tools generated from the PlanetScale API spec in the hosted server
When to use it
Useful when you work with PlanetScale-hosted MySQL databases and want an assistant to explore schema, check query insights, or run SQL without leaving the chat. The hosted endpoint is the intended path; the public repository only covers a subset of tools.
Requirements
A remote MCP endpoint at mcp.pscale.dev over streamable HTTP, with OAuth authentication required. No environment variables or headers are declared. A PlanetScale account with access to the relevant databases is implied by the OAuth flow.
Before you install
OAuth grants the server access to your PlanetScale account, so review the scopes you approve. The server can execute SQL, which may read, change or delete data in your databases; confirm statements before running them. Some tools are generated from the PlanetScale API and are not visible in the public repository.

Installation

In SourceWeft

  1. Open PlanetScale in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.planetscale%2Fmcp-server/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

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:

bash
pnpm install

Build a deployment zip:

bash
pnpm build

Push to Gram:

bash
pnpm push

Testing locally

Run a local MCP server over stdio with inspector support:

bash
pnpm dev

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

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
