@severalnines/ccx-mcp

MCP (Model Context Protocol) server for managing CCX database clusters through AI assistants like Claude Code, Claude Desktop, Cursor, and Windsurf.

Quick Start

Install from npm

Add this to your MCP client configuration:

{
  "mcpServers": {
    "ccx": {
      "command": "npx",
      "args": ["-y", "@severalnines/ccx-mcp"],
      "env": {
        "CCX_BASE_URL": "https://app.myccx.io",
        "CCX_USERNAME": "[email protected]",
        "CCX_PASSWORD": "your-password"
      }
    }
  }
}

Install from source

git clone https://github.com/severalnines/ccx-mcp.git
cd ccx-mcp
npm install
npm run build

Then point your MCP client to the built server (replace the path with where you cloned the repo):

{
  "mcpServers": {
    "ccx": {
      "command": "node",
      "args": ["/home/user/ccx-mcp/build/index.js"],
      "env": {
        "CCX_BASE_URL": "https://app.myccx.io",
        "CCX_USERNAME": "[email protected]",
        "CCX_PASSWORD": "your-password"
      }
    }
  }
}

Or use OAUTH2 credentials (create them under Accounts -> Security in the CCX UI):

    "CCX_CLIENT_ID": "your-client-id",
    "CCX_CLIENT_SECRET": "your-client-secret"

Where to put the configuration

| MCP Client | Config file | |------------|-------------| | Claude Code | .mcp.json in your project root, or ~/.claude/.mcp.json for global | | Claude Desktop | ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) | | Cursor | .cursor/mcp.json in your project root | | Windsurf | ~/.codeium/windsurf/mcp_config.json |

CCX_BASE_URL

This is the URL of your CCX deployment. If you're using the hosted CCX service, it's typically https://app.myccx.io. If you're running a self-hosted CCX instance, use its URL instead.

Using OAuth2 instead of password

Replace CCX_USERNAME and CCX_PASSWORD with CCX_CLIENT_ID and CCX_CLIENT_SECRET:

{
  "mcpServers": {
    "ccx": {
      "command": "npx",
      "args": ["-y", "@severalnines/ccx-mcp"],
      "env": {
        "CCX_BASE_URL": "https://app.myccx.io",
        "CCX_CLIENT_ID": "your-client-id",
        "CCX_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

You can create OAuth2 credentials in the CCX UI under Account > Security.

Then ask your AI assistant things like:

• "List my datastores"
• "Create a PostgreSQL cluster on AWS in eu-west-1"
• "Get the connection string for my production database"
• "Add 10.0.0.0/24 as a trusted source on my cluster"
• "Create a new database user called appuser"
• "Scale my cluster to a medium instance"
• "Show me the slowest queries on my database"
• "List backups for my production cluster"
• "What's the CPU usage on my database?"

Authentication

Password Auth

Set CCX_USERNAME and CCX_PASSWORD:

{
  "env": {
    "CCX_BASE_URL": "https://app.myccx.io",
    "CCX_USERNAME": "[email protected]",
    "CCX_PASSWORD": "your-password"
  }
}

OAuth2 (Client Credentials)

For programmatic or CI/CD use, set CCX_CLIENT_ID and CCX_CLIENT_SECRET instead:

{
  "env": {
    "CCX_BASE_URL": "https://app.myccx.io",
    "CCX_CLIENT_ID": "your-client-id",
    "CCX_CLIENT_SECRET": "your-client-secret"
  }
}

Protection Mode

Destructive operations are blocked by default to prevent accidental data loss. The following tools are affected:

• ccx_delete_datastore — deletes an entire database cluster
• ccx_delete_db_user — deletes a database user account
• ccx_delete_database — deletes a database
• ccx_delete_firewall_rule — removes a firewall access rule
• ccx_restore_backup — overwrites current data with a backup

To allow destructive operations, set CCX_PROTECT=false in your MCP configuration and restart the server:

{
  "env": {
    "CCX_PROTECT": "false"
  }
}
