Agent Plugin for VS Code and Copilot CLI

Agent plugin that bundles the PlanetScale MCP server and Database Skills for GitHub Copilot. Works with both VS Code and the Copilot CLI.

What's included

MCP Server — Authenticated access to your PlanetScale organizations, databases, branches, schema, and Insights data. No local setup required.

Database Skills — Expert knowledge for MySQL, PostgreSQL, Vitess, and Postgres sharding (Neki), loaded on-demand into Copilot's context.

Install

This plugin is being submitted to the copilot-plugins and awesome-copilot marketplaces. Once accepted, it will be discoverable via @agentPlugins in VS Code and copilot plugin marketplace browse in the CLI.

Until then, you can install it directly from this repo.

Copilot CLI

copilot plugin install planetscale/vscode-agent-plugin

See Installing plugins for more details.

VS Code

1. Clone the repo:

   git clone https://github.com/planetscale/vscode-agent-plugin.git

2. Register the plugin path in your VS Code settings (Cmd+, / Ctrl+,, search for chat.plugins.paths):

   // settings.json
   "chat.plugins.paths": {
     "/path/to/vscode-agent-plugin": true
   }

3. Reload VS Code.

Agent plugins require the chat.plugins.enabled setting to be enabled (on by default in VS Code 1.100+). See Agent plugins in VS Code for more details.

Verify it loaded

• Skills: Open the Chat view and select the gear icon > Configure Skills — you should see mysql, postgres, vitess, and neki listed
• MCP: Check the MCP server list to confirm the planetscale server is connected

Skills source and sync

Skills are sourced from the planetscale/database-skills repository. A copy lives in skills/ for install compatibility, and a Git submodule at database-skills/ tracks the upstream.

GitHub Actions runs .github/workflows/update-skills.yml weekly (with manual workflow_dispatch support). When the upstream has new commits, the workflow copies the latest skills into skills/ and opens a PR.
