list_resources

Instructions

Implementation Reference

• src/tools/resource-management.ts:146-197 (handler)

  The core handler logic for the 'list_resources' tool. It parses input parameters, selects the cloud provider adapter (AWS, Azure, or GCP), lists specified resource types (instances, storage, databases, functions), and returns a structured object with the results.

  case 'list_resources': {
    const resourceType = (params.type as string) || 'all';
    const region = params.region as string;
  
    if (provider === 'aws') {
      const adapter = new AWSAdapter(region);
      const results: Record<string, unknown[]> = {};
  
      if (resourceType === 'all' || resourceType === 'instance') {
        results.instances = await adapter.listEC2Instances();
      }
      if (resourceType === 'all' || resourceType === 'storage') {
        results.storage = await adapter.listS3Buckets();
      }
      if (resourceType === 'all' || resourceType === 'function') {
        results.functions = await adapter.listLambdaFunctions();
      }
      if (resourceType === 'all' || resourceType === 'database') {
        results.databases = await adapter.listRDSInstances();
      }
  
      return results;
    } else if (provider === 'azure') {
      const adapter = new AzureAdapter(undefined, region);
      const results: Record<string, unknown[]> = {};
  
      if (resourceType === 'all' || resourceType === 'instance') {
        results.instances = await adapter.listVirtualMachines();
      }
      if (resourceType === 'all' || resourceType === 'storage') {
        results.storage = await adapter.listStorageAccounts();
      }
  
      return results;
    } else if (provider === 'gcp') {
      const adapter = new GCPAdapter(undefined, region);
      const results: Record<string, unknown[]> = {};
  
      if (resourceType === 'all' || resourceType === 'instance') {
        results.instances = await adapter.listComputeInstances();
      }
      if (resourceType === 'all' || resourceType === 'storage') {
        results.storage = await adapter.listStorageBuckets();
      }
      if (resourceType === 'all' || resourceType === 'function') {
        results.functions = await adapter.listCloudFunctions();
      }
  
      return results;
    }
    throw new Error(`Unsupported provider: ${provider}`);
  }

• src/tools/resource-management.ts:9-33 (schema)

  The tool definition including name, description, and inputSchema for validation of parameters (provider required, type and region optional).

  {
    name: 'list_resources',
    description: 'List cloud resources (instances, storage, databases, functions) across AWS, Azure, or GCP',
    inputSchema: {
      type: 'object',
      properties: {
        provider: {
          type: 'string',
          enum: ['aws', 'azure', 'gcp'],
          description: 'Cloud provider',
        },
        type: {
          type: 'string',
          enum: ['instance', 'storage', 'database', 'function', 'all'],
          description: 'Resource type to list',
          default: 'all',
        },
        region: {
          type: 'string',
          description: 'Region to filter resources',
        },
      },
      required: ['provider'],
    },
  },

• src/server.ts:19-27 (registration)

  The 'resourceManagementTools' array (containing 'list_resources') is spread into 'allTools', which is returned by the MCP listTools handler to advertise available tools.

  const allTools = [
    ...awsTools,
    ...azureTools,
    ...gcpTools,
    ...resourceManagementTools,
    ...costAnalysisTools,
    ...monitoringTools,
    ...securityTools,
  ];

• src/server.ts:70-71 (registration)

  Dispatch logic in the MCP callTool handler that routes 'list_resources' calls (matched via resourceManagementTools) to the handleResourceManagementTool function.

  } else if (resourceManagementTools.some((t) => t.name === name)) {
    result = await handleResourceManagementTool(name, args || {});
