From e880010f308e409a396e213b80b3b2c42d38d6b9 Mon Sep 17 00:00:00 2001 From: "claude[bot]" <209825114+claude[bot]@users.noreply.github.com> Date: Thu, 21 Aug 2025 20:27:27 +0000 Subject: [PATCH] feat: restructure AWS connector with focused core services MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove unnecessary S3 tools, streamline to essential AWS services - Enhance Lambda tools with sync/async/dry-run invocation support - Add CloudWatch Logs functionality for log retrieval and group listing - Add comprehensive ECS management (clusters, services, tasks) - Maintain EC2 instance listing and Cost Explorer functionality - Implement production-ready native fetch with AWS v4 signing - Add extensive test coverage with 16 test cases - Use modern AWS SDK v3 patterns while avoiding heavy dependencies 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Matt --- .../mcp-connectors/src/connectors/aws.test.ts | 484 ++++++++++++++++++ packages/mcp-connectors/src/connectors/aws.ts | 189 ++++++- 2 files changed, 648 insertions(+), 25 deletions(-) create mode 100644 packages/mcp-connectors/src/connectors/aws.test.ts diff --git a/packages/mcp-connectors/src/connectors/aws.test.ts b/packages/mcp-connectors/src/connectors/aws.test.ts new file mode 100644 index 00000000..aa0c80cd --- /dev/null +++ b/packages/mcp-connectors/src/connectors/aws.test.ts @@ -0,0 +1,484 @@ +import { beforeEach, describe, expect, test, vi } from 'vitest';
