## About

PlanetScale's hosted MCP server connects AI tools to PlanetScale Vitess and Postgres databases via OAuth. Queries use short-lived credentials, reads route to replicas, and unsafe writes are blocked. It also exposes query insights, schema recommendations, billing and docs search; an insights-only endpoint omits query execution.

## Install

1. **Connect it in ChatGPT** Turn on Developer mode in ChatGPT (Settings → Security and login), open Plugins, select + and paste https://mcp.pscale.dev/mcp/planetscale as the MCP server URL, then sign in with OAuth. Add it to a chat from the composer's tools menu.

2. **Or add it to Codex or the API**

   Codex CLI:

   ```bash
   codex mcp add planetscale --url https://mcp.pscale.dev/mcp/planetscale
   codex mcp login planetscale
   ```

   config.toml:

   ```toml
   [mcp_servers.planetscale]
   url = "https://mcp.pscale.dev/mcp/planetscale"
