Generate a cost breakdown for Terraform infrastructure. Analyzes Terraform configuration and provides detailed cost estimates for resources. Requires infracost CLI to be installed.
AI agents call infracost_breakdown to retrieve information from Infracost MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and analyzes Terraform configuration files to produce cost estimates. It is purely a read/query operation with no side effects on infrastructure or data. The only requirement is the infracost CLI being installed. Misuse has minimal blast radius as it only reads configuration.
From the tool's definition Generate a cost breakdown for Terraform infrastructure. Analyzes Terraform configuration and provides detailed cost estimates for resources.
Attacks that exploit this kind of access
Generate a cost breakdown for Terraform infrastructure. Analyzes Terraform configuration and provides detailed cost estimates for resources. Requires infracost CLI to be installed. It is categorised as a Read tool in the Infracost MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Infracost MCP Server MCP server in PolicyLayer and add a rule for infracost_breakdown: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Infracost MCP Server. Nothing to install.
infracost_breakdown is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the infracost_breakdown rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for infracost_breakdown. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
infracost_breakdown is provided by the Infracost MCP Server MCP server (phildougherty/infracost_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
