Prompt

Our DevOps team wants to run native PromQL queries against Amazon Managed Service for Prometheus to monitor Kubernetes pod memory utilization. Is this functionality bundled within the base skill's CloudWatch server or an unbundled server?

AWS Cost & Operations

This skill provides comprehensive guidance for AWS cost optimization, monitoring, observability, and operational excellence with integrated MCP servers.

AWS Documentation Requirement

Always verify AWS facts using MCP tools (mcp__aws-mcp__* or mcp__*awsdocs*__*) before answering. The aws-mcp-setup dependency is auto-loaded — if MCP tools are unavailable, guide the user through that skill's setup flow.

Integrated MCP Servers

This plugin provides 3 MCP servers:

Bundled Servers

1. AWS Pricing MCP Server (`pricing`)

Purpose: Pre-deployment cost estimation and optimization

Estimate costs before deploying resources
Compare pricing across regions
Calculate Total Cost of Ownership (TCO)
Evaluate different service options for cost efficiency

2. AWS Cost Explorer MCP Server (`costexp`)

Purpose: Detailed cost analysis and reporting

Analyze historical spending patterns
Identify cost anomalies and trends
Forecast future costs
Analyze cost by service, region, or tag

3. Amazon CloudWatch MCP Server (`cw`)

Purpose: Metrics, alarms, and logs analysis

Query CloudWatch metrics and logs
Create and manage CloudWatch alarms
Troubleshoot operational issues
Monitor resource utilization

Note: The following servers are available separately via the Full AWS MCP Server (see aws-mcp-setup skill) and are not bundled with this plugin:

AWS Billing and Cost Management MCP — Real-time billing details

CloudWatch Application Signals MCP — APM and SLOs

AWS Managed Prometheus MCP — PromQL queries for containers

AWS CloudTrail MCP — API activity audit
