Claude Desktop supports MCP servers natively since early 2025. Adding eu-finance gives Claude real-time access to European financial data — no plugins, no browser extensions, no custom code.
What changes after installation
Before eu-finance:
“What is the ECB rate?” → Claude gives a training-data answer, possibly out of date.
After eu-finance:
“What is the ECB rate?” → Claude calls
get_ecb_rates, returns today’s exact figure with source and date.
The difference is that Claude stops guessing and starts fetching.
