Perplexity

Audit infrastructure emissions from Claude Code

Run audits on your servers directly from your terminal. Claude Code uses `estimate_emissions` to calculate the footprint of your cloud instances based on the region and runtime you specify. Because it runs on the command line, you can pipe the output of your cloud CLI directly into this MCP server to get instant carbon metrics.

Process batch emission files in your terminal

Use Claude Code to parse local CSV files containing shipping or energy data. The CLI agent uses `batch_estimate_emissions` to run up to 100 calculations in a single terminal request. This makes it easy to integrate carbon accounting into your existing shell scripts, CI/CD pipelines, or cron jobs without writing custom MCP clients.

Search Climatiq databases directly from the CLI

Find the right emission factors without opening a browser. Claude Code uses `search_emission_factors` and `list_regions` to find the exact data points you need. You can quickly verify support for different years using `list_years` or check data sources with `list_sources` right from your terminal prompt.
