dolar-mcp is an MCP (Model Context Protocol) server used to provide AI agents with real-time Argentine exchange rate data. Its core goal is to connect various Argentine exchange rate information to AI assistants, so that users can query exchange rates, perform currency conversions, and calculate exchange rate differences in natural language.
Purpose The tool is mainly aimed at AI agents and developers who need Argentine exchange rate information. It can be used to query the US dollar blue, official, MEP, CCL, crypto, and other exchange rates, and supports currency conversion and spread (exchange rate difference) calculations.
Main capabilities
- Provides multiple Argentine exchange rates: US dollar blue, oficial, MEP, CCL, crypto, etc., as well as all currencies provided by DolarAPI.
- Currency conversion: for example, converting a specified amount of US dollars to Argentine pesos at a certain exchange rate, or converting euros to Argentine pesos.
- Exchange rate difference calculation: for example, calculating the gap between the official rate and the blue rate (brecha).
- No API key required; data comes from the DolarAPI free public API, requires no authentication, and is updated in real time.
How to use Add dolar-mcp to Claude Desktop's claude_desktop_config.json, or to Cursor's .cursor/mcp.json to complete configuration. After configuration is complete, you can ask the AI assistant natural language questions, such as:
- "Dame todas las cotizaciones del dolar"
- "Cuanto sale el dolar blue hoy?"
- "Converti 500 USD blue a pesos"
- "Cual es la brecha entre el oficial y el blue?"
- "Cuanto esta el euro?"
- "Converti 1000 EUR a ARS" It can also be used programmatically.
Use cases Suitable for AI assistant conversation scenarios that require Argentine exchange rate queries, such as daily exchange rate queries, cross-currency conversion, comparing the gap between different exchange rates, etc.
Limitations The materials do not provide more details about fees, pricing, specific platform compatibility scope, conversion accuracy, or usage steps; apart from the known DolarAPI data sources and MCP configuration methods, no other information is currently provided.
