Infracost Cost Estimation

Analyze infrastructure as code (IaC) projects to estimate cloud costs, identify savings opportunities, and flag FinOps policy violations.

Supported IaC types: Terraform, CloudFormation, Terragrunt. CDK is not yet directly supported.

This plugin ships an MCP server (infracost mcp) that's started automatically when the plugin loads. Every operation in this skill is an MCP tool call — there are no shell commands to run, no JSON files to parse, no flags to remember.

Important: Verify the Infracost CLI is installed, the user is authenticated, and an organization is selected before running any scans.

Workflow

1. Run a scan

Call the scan tool with the absolute path to the IaC directory:

scan(path="/abs/path/to/repo")
