Spotinfo MCP Server
Spotinfo MCP server enabling AI agents to query AWS EC2 Spot Instance pricing, interruption rates, and availability — comparing spot prices across instance types and availability zones, checking historical interruption frequency, identifying cost-optimal instance types for workloads, and integrating cloud cost optimization into agent-driven infrastructure planning and Kubernetes cluster optimization workflows.

⚡ Reliability
Best When
A platform engineer or DevOps team using AWS needs AI-assisted spot instance selection — optimizing for cost versus interruption risk for batch, ML training, or Kubernetes workloads.
Avoid When
You're on Azure, GCP, or don't use AWS EC2 spot instances.
Use Cases
- • Comparing AWS Spot Instance prices across instance types from cost optimization agents
- • Checking spot interruption rates for reliability planning from infrastructure agents
- • Identifying cheapest spot instances for batch workloads from cost management agents
- • Optimizing Kubernetes node pools with spot instance data from platform engineering agents
- • Planning EMR, ECS, or Batch workloads with spot availability from data pipeline agents
- • Monitoring spot price changes for budget alert agents
Not For
- • Non-AWS clouds (Azure spot, GCP preemptible instances require different tools)
- • On-demand instance pricing (Spotinfo focuses on spot/preemptible pricing)
- • Teams not using EC2 or AWS compute services
Interface
Authentication
No authentication required for public spot pricing data. Spotinfo uses publicly available AWS spot pricing API and spot interruption data. No AWS credentials needed for basic functionality.
Pricing
Free open source tool. AWS spot pricing data is publicly available. No AWS account or credentials required.
Agent Metadata
Known Gotchas
- ⚠ Spot pricing data is near-real-time — prices can change rapidly in hot AZs
- ⚠ Interruption rate data is historical — past rates don't guarantee future interruptions
- ⚠ Not a real-time AWS API client — may have data freshness lag
- ⚠ Useful for planning, not for millisecond-precise pricing decisions
- ⚠ Community MCP from alexei-led — experienced cloud tools author
- ⚠ Covers AWS primarily — other cloud providers require different tools
