Team-wide GSA lodging lookups in VS Code Copilot

The GSA Per Diem Rates MCP Server integrates directly with VS Code Copilot to provide instant lodging lookups for your team. By committing the server configuration to your repository, every developer can use `get_conus_lodging` to verify travel policy code against official federal limits. This ensures that everyone on your team is building with the exact same financial limits in VS Code. Copilot reads the live rates and suggests code that is fully compliant with the latest fiscal year guidelines.

Automate meal expense logic with Copilot Chat

This MCP Server allows VS Code Copilot to execute the `get_mie_breakdown` tool during your coding sessions. If you are writing a service to parse travel vouchers, Copilot can call this tool to verify the exact breakfast, lunch, and dinner limits. It speeds up the development of financial compliance software by removing manual data entry from VS Code. You can ask Copilot in the chat sidebar to write a parsing algorithm and test it against the real M&IE breakdown.

Query precise geographic rates in your editor

The GSA Per Diem Rates toolset lets your team query locations using `get_rates_by_zip`, `get_rates_by_city`, and `get_rates_by_state` inside VS Code Copilot. This helps you build applications that handle complex municipal boundaries without errors. The server also includes `get_zip_mapping` to resolve zip codes to counties quickly inside VS Code. Copilot uses these tools to help you write accurate geospatial database queries for your travel management systems.
