How to Set Up and Use AWS Spot Instance CLI
Spotinfo is a CLI tool and MCP server for exploring AWS EC2 Spot Instance inventory, giving AI assistants access to live Spot price data, interruption frequency statistics, placement scores, and savings compared to On-Demand pricing. It integrates with the AWS Spot Advisor dataset and optionally fetches live pricing via the EC2 API, making it valuable for DevOps teams optimizing cloud costs or selecting the right instance types for fault-tolerant workloads. Through its MCP interface, Claude can answer questions like 'which m5 instance type has the best spot savings and lowest interruption rate in us-east-1?'
Prerequisites
- spotinfo binary installed (via Homebrew, direct download, or Go build)
- AWS credentials optionally configured for placement scores and live pricing (requires ec2:DescribeSpotPriceHistory and ec2:GetSpotPlacementScores IAM permissions)
- Go 1.24+ if building from source
- Claude Desktop or another MCP-compatible client
Install spotinfo
Install the spotinfo binary using Homebrew on macOS, or download the release binary for Linux/Windows.
# macOS
brew tap alexei-led/tap
brew install alexei-led/tap/spotinfo
# Linux (amd64)
curl -L https://github.com/alexei-led/spotinfo/releases/latest/download/spotinfo_linux_amd64.tar.gz | tar xz
sudo mv spotinfo /usr/local/bin/Verify the installation
Run spotinfo to confirm the binary is accessible and check the version.
spotinfo --versionConfigure AWS credentials (optional but recommended)
Configure AWS credentials to enable live pricing and placement score features. Without credentials, spotinfo falls back to cached Spot Advisor data.
aws configure
# Ensure the IAM entity has:
# - ec2:DescribeSpotPriceHistory
# - ec2:GetSpotPlacementScoresAdd the MCP server to your client config
Add the spotinfo MCP server to your Claude Desktop configuration. The --mcp flag starts spotinfo in MCP server mode.
{
"mcpServers": {
"spotinfo": {
"command": "spotinfo",
"args": ["--mcp"]
}
}
}Restart Claude Desktop and query Spot data
Restart Claude Desktop and ask it about AWS Spot instances. The server will respond with pricing, interruption frequency, and placement scores from AWS Spot Advisor.
AWS Spot Instance CLI Examples
Client configuration
Add this to your Claude Desktop claude_desktop_config.json. The spotinfo binary must be on your PATH.
{
"mcpServers": {
"spotinfo": {
"command": "spotinfo",
"args": ["--mcp"]
}
}
}Prompts to try
Use these prompts to explore Spot instance options and optimize costs through Claude.
- "What are the cheapest m5 Spot instances in us-east-1 with a low interruption rate?"
- "Compare Spot savings and interruption frequency for c5.xlarge across us-east-1 and eu-west-1"
- "Find Spot instances with 4 vCPUs and 16 GB RAM that have a placement score above 8"
- "Which t3 instance types have the highest Spot savings percentage right now?"
- "Show me all Spot instances matching 'c5.*' sorted by interruption frequency"Troubleshooting AWS Spot Instance CLI
'spotinfo: command not found' when Claude tries to start the server
Ensure the spotinfo binary is installed and on the PATH that Claude Desktop uses. On macOS, use the full binary path in the command field (e.g., '/usr/local/bin/spotinfo') or run 'which spotinfo' to find it.
Placement scores not available or returning zero
Placement scores require valid AWS credentials with ec2:GetSpotPlacementScores permission. Run 'aws sts get-caller-identity' to confirm credentials are active, and verify the IAM policy includes the required EC2 actions.
Spot data appears stale or outdated
Spotinfo uses the AWS Spot Advisor dataset as its primary source, which is updated periodically. For live prices, ensure AWS credentials are configured so spotinfo can call ec2:DescribeSpotPriceHistory. Pass --region explicitly if you need data for a specific region.
