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: 2,700+ instance types across all providers
  • AWS: 1,147 EC2 instances + 353 RDS database types + Lightsail
  • Azure: 1,199 VM types
  • GCP: 287 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)
• Real-Time Pricing: All providers have real-time refresh capability
• 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

Installation

For Claude Code Users

# One-command install
claude mcp add cloud-cost -- npx cloud-cost-mcp

Manual Installation

npm install -g cloud-cost-mcp

Then add to your Claude Code configuration:

{
  "mcpServers": {
    "cloud-cost": {
      "command": "cloud-cost-mcp"
    }
  }
}

Usage Examples

Once installed, just ask Claude:

Compare Compute

"Compare 4 vCPU 16GB VMs across AWS, Azure, GCP, and OCI"
"Find the cheapest cloud for an 8-core VM with 32GB RAM"
"What's the best deal for ARM instances with 4 cores?"

Compare Storage

"Compare object storage pricing for 1TB across all clouds"
"What's the cheapest archival storage for 10TB?"

Compare Egress (OCI Advantage!)

"Compare egress costs for 5TB monthly"
"What's the cheapest cloud for 10TB data transfer?"

Note: OCI offers 10TB/month free egress - 100x more than AWS/Azure/GCP!

Full Workload Estimates

"Estimate cost for 3 VMs with 4 vCPU each, 500GB storage, and 1TB egress"
"What would a Kubernetes cluster with 5 nodes cost across all clouds?"

Quick Estimates

"Quick estimate for a medium API server"
"Compare all clouds for a kubernetes-cluster preset"
"Estimate cost for gpu-training-large preset"

GPU Pricing (OCI)

"List all available GPU shapes"
"Compare A100 vs H100 GPU pricing"
"What GPU should I use for ML training with 80GB memory?"
"Get details for BM.GPU.H100.8"

Migration Planning

"How much could I save migrating from AWS to OCI?"
"Compare my current GCP setup against other clouds"
