# Google Cloud SQL MCP server

> Create and manage Cloud SQL instances, users and backups, and run SQL queries against them.

- Listing: https://mcp.tc/i/cloud-sql
- Connect: use the server's own URL `https://sqladmin.googleapis.com/mcp` (OAuth sign-in at the server); clients connect to it directly. The listing link is a page, not an MCP endpoint.
- Type: remote (Streamable HTTP)
- Auth: OAuth sign-in
- Category: [Databases & Backend](https://mcp.tc/c/databases)
- Vendor: Google Cloud
- Verified: yes, mcp.tc checked that this is the official server (https://mcp.tc/verify). It says who runs the server, not that it is safe.

## About

Connects to the Cloud SQL Admin API for MySQL, PostgreSQL and SQL Server. You can list, create, clone and update instances, manage database users, take and restore backups, import data, and run SQL statements, including a read-only query tool. Long-running operations are tracked with a status tool.

Runs as a hosted streamable HTTP endpoint at https://sqladmin.googleapis.com/mcp. Access uses Google OAuth 2.0 and IAM permissions on your project. SQL execution requires the instance to have Data API access enabled and, for IAM users, IAM database authentication turned on.

## What it can do

- List and inspect Cloud SQL instances
- Create, clone and update instances
- Create and update database users
- Run read-only or full SQL statements
- Take and restore backups
- Import data from Cloud Storage
- Check long-running operation status
- Run PostgreSQL major version upgrade prechecks

## Example prompts

- "List all Cloud SQL instances in my project my-project"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http cloud-sql https://sqladmin.googleapis.com/mcp
```

2. Start Claude Code, type `/mcp`, pick **cloud-sql** and choose **Authenticate**. A browser window opens for the Google Cloud sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Google Cloud SQL** and paste this URL:

```url
https://sqladmin.googleapis.com/mcp
```

3. Click **Add**, then **Connect**, and sign in when Google Cloud asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Google%20Cloud%20SQL&connectorUrl=https%3A%2F%2Fsqladmin.googleapis.com%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://sqladmin.googleapis.com/mcp` and click **Add**.

3. Click **Connect** and sign in when Google Cloud asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://sqladmin.googleapis.com/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Google Cloud to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=cloud-sql&config=eyJ1cmwiOiJodHRwczovL3NxbGFkbWluLmdvb2dsZWFwaXMuY29tL21jcCJ9>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "cloud-sql": {
      "url": "https://sqladmin.googleapis.com/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=cloud-sql&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fsqladmin.googleapis.com%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"cloud-sql","type":"http","url":"https://sqladmin.googleapis.com/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "cloud-sql": {
      "type": "http",
      "url": "https://sqladmin.googleapis.com/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "cloud-sql": {
      "serverUrl": "https://sqladmin.googleapis.com/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add cloud-sql --url https://sqladmin.googleapis.com/mcp
codex mcp login cloud-sql
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.cloud-sql]
url = "https://sqladmin.googleapis.com/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http cloud-sql https://sqladmin.googleapis.com/mcp
```

Then, inside Gemini CLI, run `/mcp auth cloud-sql` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "cloud-sql": {
      "type": "http",
      "url": "https://sqladmin.googleapis.com/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://sqladmin.googleapis.com/mcp`.
