With PlanetScale MCP support, AI tools like Claude or Cursor can directly access read-only database information to answer your questions about your database.

​
Installation

We have two new CLI Commands you can use to get up and running: 
pscale mcp install --target claude # Installs PlanetScale MCP server in Claude Desktop
pscale mcp server                  # Enables Claude to perform read-only database interactions
The --target flag accepts claude or cursor. You can get started using Claude or Cursor. Other tools should accept a configuration similar to the Cursor configuration.

​
Claude Desktop:

1

Upgrade to the latest version of pscale CLI
2

Run pscale mcp install --target claude
3

Restart Claude Desktop

​
Cursor

Add the following to your .cursor/mcp.json in your project or home directory: 
{
  "mcpServers": {
    "planetscale": {
      "args": [
        "mcp",
        "server"
      ],
      "command": "pscale"
    }
  }
}

​
Use cases

Using this functionality allows you to interact with your PlanetScale organizations and databases right from your AI tooling. You can ask questions like “How many users do I have in North Carolina?” or “How many rows are in my messages table?”. Claude or your preferred AI coding tool will then be able to access road-only information from your PlanetScale account to give bespoke answers.
