Azure SQL

Quick Start

  1   Add to your AI agent

CLI agents — one command, done:

# Claude Code (Anthropic)
claude mcp add --transport stdio --scope user azure-sql -- npx -y mcp-azure-sql

# Codex CLI (OpenAI)
codex mcp add azure-sql -- npx -y mcp-azure-sql

# Gemini CLI (Google)
gemini mcp add -s user azure-sql npx -y mcp-azure-sql

IDE agents — add this JSON block to your agent's config file:

{
  "azure-sql": {
    "command": "npx",
    "args": ["-y", "mcp-azure-sql"],
    "env": {
      "AZURE_SQL_CONFIG_FILE": "~/.config/azure-sql-mcp/connections.json"
    }
  }
}

Agent	File	Key
	VS Code settings.json	"mcp" > "servers"
	~/.cursor/mcp.json	"mcpServers"
	~/.codeium/windsurf/mcp_config.json	"mcpServers"
	Cline Settings UI or cline_mcp_settings.json	"mcpServers"
	~/.continue/config.yaml	mcpServers: (YAML)
	claude_desktop_config.json	"mcpServers"

  2   Configure your databases

Create ~/.config/azure-sql-mcp/connections.json:

{
  "defaults": { "auth": "azuread" },
  "connections": [
    {
      "name": "dev",
      "server": "myserver.database.windows.net",
      "database": "myapp-dev",
      "environment": "dev"
    },
    {
      "name": "prod",
      "server": "myserver.database.windows.net",
      "database": "myapp-prod",
      "environment": "prod",
      "prod": true
    }
  ]
}

See example-config.json for SQL auth, connection strings, and all options.

  3   Sign in to Azure

az login

  ✓   Done

Restart your AI agent. You now have 34 database tools.

Tools

Safety

Your AI agent cannot accidentally destroy production.

Production = any connection with "prod": true or "environment": "prod".

Authentication

Why Go?

Config file

{
  "defaults": { "auth": "azuread", "app_name": "my-app" },
  "connections": [{
    "name": "unique-name",
    "server": "server.database.windows.net",
    "database": "dbname",
    "auth": "azuread",
    "environment": "dev",
    "description": "Human-readable note",
    "prod": false
  }]
}

Environment tags: dev sqa qa beta delta test preprod prod

Environment variables

# Legacy (no config file needed)
export AZURE_SQL_CONNECTIONS="dev=server.database.windows.net/mydb;qa=qaserver.database.windows.net/qadb"

# Override production list
export AZURE_SQL_PROD_CONNECTIONS="my-prod-db,my-staging-db"
