Perplexity

Query 170+ federal datasets from your terminal

The `query_dataset` tool gives Claude Code direct access to the entire U.S. Treasury API catalog from your CLI. You pass the endpoint path and your filter criteria, and the raw data dumps straight into your shell. This lets you inspect ledger entries, debt figures, and historical accounts without ever leaving your terminal or opening a browser. Skip writing custom wrapper scripts or parsing raw JSON payloads manually. Your terminal agent handles the API calls directly, parsing the Treasury's response so you can pipe the output to other CLI utilities. It turns complex government endpoints into simple commands you can run inside any SSH session.

Track federal finances with this MCP Server

The `get_mts_table_1` and `get_mts_table_9` tools fetch the Monthly Treasury Statement tables directly into your terminal. Table 1 tracks the overall summary of receipts and outlays, while Table 9 breaks down the federal trust funds and domestic accounts. You get the raw financial truth of the federal budget without dealing with clunky PDF reports. Having Claude Code fetch these tables lets you run automated checks on federal spending patterns. You can instruct your terminal client to pull the latest monthly figures, parse the columns, and alert you if specific budget thresholds are crossed. It is a direct line to the nation's ledger, built for headless terminal environments.

Automate foreign exchange checks in Claude Code

The `get_rates_of_exchange` tool pulls official Treasury reporting rates directly into your active terminal workspace. This tool gets the latest quarterly and daily exchange rates that government agencies use to settle international transactions. You don't have to manually look up external currency tables when verifying overseas ledger items. Because Claude Code runs headless, you can script this tool to run in your cron jobs or deployment pipelines. When a transaction requires currency conversion, the agent grabs the exact Treasury rate, validates the math, and outputs the result. It keeps your financial automation scripts tied to the official government source of truth using this MCP connection.
