• src/tools.js:365-411 (handler)

  The main handler function for the 'azure_acr_setup' tool. It validates inputs, creates a resource group if needed, and sets up an Azure Container Registry (ACR) using Azure CLI commands.

  export async function azureAcrSetup({ name, resource_group, location, sku }) {
    if (!/^[a-zA-Z0-9]{5,50}$/.test(name)) {
      return {
        content: [{
          type: "text",
          text: `Invalid registry name: "${name}"\n\nRules:\n- 5-50 characters\n- Alphanumeric only (no hyphens or underscores)\n- Must be globally unique`
        }]
      };
    }
  
    // Check if resource group exists
    const rgCheck = await commandRunner(`az group show -n ${resource_group} 2>/dev/null`);
    let output = "";
  
    if (!rgCheck.success) {
      output += `Creating resource group: ${resource_group}...\n`;
      const rgCreate = await commandRunner(`az group create -n ${resource_group} -l ${location}`);
      if (!rgCreate.success) {
        return {
          content: [{
            type: "text",
            text: `Failed to create resource group!\n\nError: ${rgCreate.stderr || rgCreate.error}`
          }]
        };
      }
      output += `Resource group created.\n\n`;
    }
  
    output += `Creating container registry: ${name}...\n`;
    const acrCreate = await commandRunner(
      `az acr create -n ${name} -g ${resource_group} --sku ${sku} --admin-enabled true`,
      { timeout: 120000 }
    );
  
    if (!acrCreate.success) {
      return {
        content: [{
          type: "text",
          text: `Failed to create registry!\n\nError: ${acrCreate.stderr || acrCreate.error}`
        }]
      };
    }
  
    output += `\nRegistry created successfully!\n\nName: ${name}\nResource Group: ${resource_group}`;
  
    return { content: [{ type: "text", text: output }] };
  }

• src/tools.js:576-597 (registration)

  The tool is registered by being included in the exported 'tools' object, which likely gets used by the MCP server to expose the tools.

  export const tools = {
    // Git

    gitCommitGuided,
