FAQ from GSA Per Diem MCP

What dependencies or runtime are required?

A free api.data.gov key (1,000 requests/hour) and an MCP‑compatible client (Claude Desktop, Codex, Gemini CLI, Copilot, etc.). The server runs via uvx or as a Python package.

Where does the data come from?

All rates are sourced from the official GSA Per Diem Rates API (api.data.gov). No local data storage; every call fetches live government data.

Are there any known rate limits or transport constraints?

The API enforces a 1,000 requests per hour limit. The server uses standard I/O (stdio) transport; no HTTP or WebSocket transport is mentioned.

How is authentication handled?

The API key is passed to the server via the PERDIEM_API_KEY environment variable. No other authentication method is described.

Does it handle edge cases like non‑listed locations or first/last travel days?

Yes. The server includes standard‑rate fallbacks for non‑listed locations, first/last day M&IE at 75% per FTR 301‑11.101, and monthly seasonal rate variations. It has been tested across multiple fiscal years.
