Terminal-driven rate lookups with Claude Code

The GSA Per Diem Rates MCP Server runs directly in your terminal, making it perfect for quick command-line lookups. You can ask Claude Code to query `get_rates_by_zip` directly from a shell prompt to get instant lodging limits for any U.S. destination. This command-line setup fits perfectly into shell scripts. You can pipe a list of ZIP codes to Claude Code, and the agent will fetch the rates in real-time, outputting the results as clean JSON or raw text.

Fast state-wide rate extraction

This MCP-enabled rate lookup tool lets Claude Code pull massive regional datasets directly into your shell. Claude Code can execute `get_rates_by_state` to dump all city and county rates for a specific state directly into your terminal. The agent can then grep, sort, or format this data into custom markdown tables. It eliminates the need to navigate clunky federal search portals or download massive PDF tables.

Scriptable meal and lodging breakdowns

The lodging and meal breakdown tools let you script automated compliance checks inside Claude Code. For terminal-based CI/CD pipelines, Claude Code can pull precise daily limits using `get_mie_breakdown` and `get_conus_lodging`. By integrating `get_zip_mapping`, Claude Code can resolve high volumes of ZIP codes to their official GSA destination IDs. This reduces API overhead and keeps your automated scripts running fast.
