How to Use the Infracost MCP in Cursor

Q: Can Infracost in Cursor check my terraform files?

Yes. By using the querypricing tool, your agent reads your terraform definitions and maps them against cloud provider rates to show you estimated costs.

Q: How does Infracost in Cursor secure my pricing data?

Your custom price books are loaded via ingestpricebook and remain scoped to your organization. The server ensures that your sensitive contract details stay isolated and secure.

Q: What happens to my data if I delete a guardrail in Cursor?

When you call deleteguardrail, the policy is immediately removed from your active configuration. The server ensures your cost monitoring stays aligned with your current project needs.

Perplexity

Instant pricing queries in Cursor

Run complex cost calculations without switching windows. Use `query_pricing` with a GraphQL string to pull exact numbers for any resource configuration you are currently drafting. Your agent fetches live data, giving you immediate feedback on the financial impact of your architectural choices. You stop provisioning expensive resources by accident.

Manage guardrails as code

Treat your cloud budget like your application code. Use `create_guardrail` and `update_guardrail` to define cost policies that live right alongside your project configuration. When you ask your agent to review your code, it applies these guardrails to your Terraform files. It catches expensive misconfigurations before you even commit your changes.

Integrate custom enterprise pricing

Bring your company's negotiated cloud rates into your editor. Use `get_price_book_files_url` to prep your data and `ingest_price_book` to load it into the server for accurate estimation. Your agent uses these custom books to provide realistic cost projections. This eliminates the gap between developer estimates and actual monthly cloud invoices.
