Perplexity

Fetch daily PTAX rates via MCP Server

`get_cotacao_dolar` grabs the official BRL/USD reference rate straight from the Brazilian Central Bank. You ask Claude for today's dollar value, and the agent pulls the exact buy and sell figures calculated from authorized dealers. No more switching tabs to check financial portals. Need something other than the dollar? `get_cotacao_moeda` handles over 150 global currencies. You can check the Euro, Japanese Yen, or even the Thai Baht against the Brazilian Real while building financial reports inside the Claude web app.

Browse the complete foreign exchange catalog

`listar_moedas` outputs the full registry of available currency codes recognized by the Central Bank. Claude uses this to figure out exactly which ticker you need before making a quote request. This matters when you deal with exotic pairs. If a client asks for the Chilean Peso rate, Claude hits the registry first, finds CLP, and then pulls the exact daily quote without guessing the symbol.

Plot long-term historical currency trends

`get_dolar_periodo` extracts up to a year of daily PTAX bulletins, including opening and closing marks. Feed Claude a date range, and it pulls the entire series so you can spot pricing trends over the last few months. For massive datasets that go back years, `get_dolar_sgs` taps the SGS system. Your agent grabs decades of commercial dollar buy/sell marks, letting you generate deep historical context right inside your local desktop environment.

The integration supports over 150 currencies mapped by the Brazilian Central Bank. Claude runs listar_moedas to find the exact code, then pulls the specific buy and sell rates for everything from EUR to MXN.
