How much did we spend on S3 in us-east-1 over the last 30 days?Claude responds:
I’ll help you find your S3 spending in us-east-1 over the last 30 days. First, let me check your workspace information and available cost providers.The MCP’s
get-myself
tool is then used to retrieve:
I can see you have access to multiple workspaces. To get your S3 spending data, I’ll need to know which workspace you’d like me to query. I’ll start with the first workspace (‘Marketing Workspace’) and check for AWS S3 costs.Now that Claude has the necessary context, it calls the MCP’s
query-costs
tool with scoped filters:
It looks like there are no S3 costs in us-east-1 for Marketing Workspace. Let me try a few other workspaces to see if your S3 costs might be in a different workspace. Let me check the “Management” workspace which seems like it might be a primary workspace.It then uses the
query-costs
tool again to look in other workspaces until it finds spend in a workspace:
Based on your query for S3 costs in us-east-1 over the last 30 days (June 22 - July 22, 2025), here’s what I found: S3 Spending Summary (us-east-1, Last 30 Days) Total S3 Spend: $55,089.92 The costs are distributed across multiple AWS accounts: Top Spending Accounts: - Account 123456789: ~$25,850+ (dominant portion of spend) …In addition, daily spending patterns and other insights are provided.
How much did we spend on S3 in us-east-1 over the last 30 days in the Management Workspace?Claude would immediately have the necessary context and could skip the workspace confirmation step, which would result in a quicker, more relevant response.
