Implementation Reference
- src/adapters/aws-adapter.ts:177-206 (handler)Core handler implementation that initializes AWS LambdaClient, executes ListFunctionsCommand, maps AWS response to LambdaFunction objects, and handles errors.
async listLambdaFunctions(): Promise<LambdaFunction[]> { await this.initializeClients(); if (!this.lambdaClient) throw new Error('Lambda client not initialized'); try { const command = new ListFunctionsCommand({}); const response = await this.lambdaClient.send(command); const functions: LambdaFunction[] = []; for (const func of response.Functions || []) { functions.push({ id: func.FunctionArn || '', type: 'function', name: func.FunctionName || '', region: this.region, status: 'running', functionName: func.FunctionName || '', runtime: func.Runtime || '', memorySize: func.MemorySize, timeout: func.Timeout, lastModified: func.LastModified ? new Date(func.LastModified) : undefined, }); } return functions; } catch (error) { throw new Error(`Failed to list Lambda functions: ${error instanceof Error ? error.message : String(error)}`); } } - src/tools/aws-tools.ts:134-147 (handler)Tool-specific handler case within handleAWSTool that calls the AWS adapter and formats the response with total count and simplified function list.
case 'aws_list_lambda_functions': { const functions = await adapter.listLambdaFunctions(); return { total: functions.length, functions: functions.map((func) => ({ id: func.id, name: func.functionName, runtime: func.runtime, memorySize: func.memorySize, timeout: func.timeout, region: func.region, })), }; } - src/tools/aws-tools.ts:33-46 (registration)Tool registration entry in awsTools array, including name, description, and input schema for optional region parameter.
{ name: 'aws_list_lambda_functions', description: 'List all Lambda functions in AWS', inputSchema: { type: 'object', properties: { region: { type: 'string', description: 'AWS region', default: 'us-east-1', }, }, }, }, - src/types/index.ts:45-52 (schema)TypeScript interface defining the structure of LambdaFunction objects returned by the tool.
export interface LambdaFunction extends AWSResource { type: 'function'; functionName: string; runtime: string; memorySize?: number; timeout?: number; lastModified?: Date; } - src/server.ts:64-65 (registration)Top-level MCP server dispatch logic that identifies AWS tools and routes calls to handleAWSTool.
if (awsTools.some((t) => t.name === name)) { result = await handleAWSTool(name, args || {});
