Compare managed Kubernetes costs across AWS (EKS), Azure (AKS), GCP (GKE), and OCI (OKE), including control plane and node pricing.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Cloud Cost MCP Compare 4 vCPU 16GB VMs across AWS, Azure, GCP, and OCI"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.
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?"

claude mcp add cloud-cost-dev -- node /path/to/cloud-cost-mcp/dist/index.jsThis server uses a two-tier data model — it helps to know which is which:
Bundled data (src/data/bundled/*.json) is what the comparison/calculator tools
read by default, so the server works instantly with no network calls.
AWS, Azure, GCP bundled data is regenerated from live upstream sources
(instances.vantage.sh + the official Azure Retail Prices API) and auto-refreshed
weekly via the refresh-data GitHub Action.
You can also regenerate locally with npm run fetch-data.
OCI bundled data is curated (vantage.sh has no OCI feed) and updated manually.
For always-live OCI pricing, use the refresh_oci_pricing tool or the dedicated
oci-pricing-mcp.
Live refresh tools (refresh_aws_ec2_pricing, refresh_azure_full_pricing,
refresh_gcp_pricing, refresh_oci_pricing, refresh_aws_rds_pricing) fetch current
pricing from provider APIs at call time, cached 60 minutes in-memory for the life of
the process. These return fresh data to the caller but do not rewrite the bundled
files — that only happens via npm run fetch-data / the weekly Action.
Use get_data_freshness to see the bundled timestamp and staleness for each provider.

Scored across 31 tools
Each tool targets a specific combination of cloud provider and resource type (e.g., compare_compute, compare_egress, compare_storage, etc.), with no overlapping functionality. The descriptions clearly delineate their distinct purposes.
All tool names follow a consistent verb_noun pattern in snake_case (e.g., calculate_workload_cost, list_aws_regions, refresh_oci_pricing). The prefixes (get_, list_, compare_, refresh_) are semantically clear and uniformly applied.
With 31 tools, the server exceeds the 25+ threshold considered too many for typical scope. While the breadth of cloud providers and resource types partially justifies this, many tools could be consolidated (e.g., unifying refresh_* tools or combining compare_* tools).
The tool set covers the full lifecycle of cloud cost estimation: compute, storage, egress, GPU, Kubernetes, migration savings, and data freshness. Missing aspects like specific database or network pricing are out of scope, making the surface complete for its intended domain.
