Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`convert`read-only	Convert an amount from one currency to another. Returns {amount, currency} rounded to the target's minor units. Upstream rounds rates per direction; for low-value sources, flip via `get_rates` for more precision. Pass `provider` to use one institution's published rate, e.g. UST for a U.S. Treasury reporting rate.
`get_rates`read-only	Latest or a single day's exchange rates. The raw-rate companion to `convert`. With `provider`, published rates from one or more institutions: on its own base the digits are as published, with the date they took effect.
`list_currencies`read-only	List all supported ISO 4217 currency codes and their full names (e.g. { 'USD': 'United States Dollar' }).
`list_providers`read-only	List the institutions whose rates Frankfurter relays, with key, rate type, frequency (daily, monthly or quarterly) and coverage dates. Use a key as `provider` in `convert` or `get_rates` for that institution's published rates instead of the blend.

Schemas: list_tools.
