• index.js:164-191 (registration)

  MCP server request handler for calling tools, which dispatches to the specific tool handler based on the tool name.

      ddClient = initializeDoorDashClient();
      if (!ddClient) {
        throw new Error('DoorDash client not initialized. Please set environment variables.');
      }
    }
  
    const { name, arguments: args } = request.params;
    const tool = TOOLS.find((t) => t.name === name);
    if (!tool) {
      throw new Error(`Unknown tool: ${name}`);
    }
  
    try {
      const response = await tool.handler(ddClient, args);
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(response.data, null, 2),

• index.js:29-44 (helper)

  Helper function to initialize the DoorDashClient instance used by all tool handlers, including create_delivery_quote.

  function initializeDoorDashClient() {
    const developerId = process.env.DOORDASH_DEVELOPER_ID;
    const keyId = process.env.DOORDASH_KEY_ID;
    const signingSecret = process.env.DOORDASH_SIGNING_SECRET;
    
    if (!developerId || !keyId || !signingSecret) {
      console.error('Missing required DoorDash environment variables: DOORDASH_DEVELOPER_ID, DOORDASH_KEY_ID, DOORDASH_SIGNING_SECRET');
      return null;
    }
    
    return new DoorDashClient({
      developer_id: developerId,
      key_id: keyId,
      signing_secret: signingSecret,
    });
  }
