Production-grade MCP server for US federal spending data via [api.usaspending.gov](https://api.usaspending.gov).

## Features

- **Dual transport:** STDIO (Claude Desktop/Code) and Streamable HTTP + SSE (hosted deployments)
- **Progress notifications** for long-running paginated searches and bulk downloads
- **4 MCP resources:** agencies list, current fiscal year, data freshness, glossary
- **Lazy-loaded reference data** with TTL cache (no blocking startup calls)
- **No authentication required** — USASpending API is public
