jasonwilbur/cloud-cost-mcp

Multi-cloud pricing comparison MCP server for AWS, Azure, GCP, and OCI. Compare compute, storage, egress, and Kubernetes costs across all major cloud providers with a single query.
> **⚠️ DISCLAIMER**: All pricing data is retrieved from publicly available APIs and data sources including instances.vantage.sh, Azure Retail Prices API, and Oracle Cloud Price List API. This data is provided for informational and estimation purposes only. **Cloud pricing changes frequently and may vary by region, account type, commitment terms, and other factors.** Users are solely responsible for verifying all pricing information directly with cloud providers before making any purchasing or architectural decisions. The authors make no warranties about the accuracy, completeness, or timeliness of this data.
Features
- **Comprehensive Coverage**: 4,900+ instance types across all providers
- AWS: 1,300+ EC2 instances + 1,180+ managed-database types + Lightsail
- Azure: 1,680+ VM types (official Azure Retail Prices API)
- GCP: 360+ instance types across 40+ regions
- OCI: 600+ products via Oracle API
- **No API Keys Required**: All data from public APIs (instances.vantage.sh + provider APIs)
- **Fresh data, two ways**: AWS/Azure/GCP bundled data is auto-refreshed weekly via GitHub Actions, and the refresh_* tools fetch live pricing on demand (cached 60 min in-memory). OCI bundled data is curated. See Data freshness for the exact model.
- **Natural Language Queries**: Ask Claude "What's cheapest for 4 vCPU 16GB?"
- **Workload Calculator**: Estimate full workload costs including compute, storage, and egress
- **Migration Planning**: Calculate potential savings when switching providers
