Access and checks

How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • Installs via pipx and fetches rates, the key rate and inflation from cbr.ru XML and SOAP endpoints
  • Needs no keys and caches responses

This is third-party code. Review the repository files before installing.

What it does

The server exposes five tools: a currency rate on a date (get_rate), rate history over a period (history_rates), the key rate over a period (key_rate), monthly year-over-year inflation (inflation), and a combined get_statistics snapshot with the key rate, USD/EUR/CNY rates and inflation in one response. All data is read from public XML and SOAP endpoints on cbr.ru through an async httpx client with automatic retries on 5xx errors and safe XML parsing via defusedxml. A built-in TTL cache holds daily quotes for an hour and historical series for a day, to avoid hammering the source.

Who it is for. For people who want a ready, well-tested source of Bank of Russia rates and the key rate without writing their own parser.

Good fit when

  • You need an official rate on a date or rate history over up to 366 days
  • You want a single combined macro snapshot in one call (key rate plus main currencies plus inflation)
  • It matters that the data source is covered by tests on offline fixtures, not just manual checks

Not a fit when

  • You need history over more than 366 days in one call: you will need to split the request
  • You need precious metal prices: this server does not provide them, unlike some alternatives

Example request

Plot the USD/RUB rate over the last 90 days and give me the combined macro snapshot

Environment variables

MCP_CBR_HTTP_TIMEOUT
HTTP timeout for CBR calls in seconds, defaults to 15

Limitations

The server is unofficial and not affiliated with the Bank of Russia, which the author states explicitly, disclaiming responsibility for data accuracy. The history_rates window is capped at 366 days per call. There are no precious metal prices. If cbr.ru's HTML or XML schemas change, individual tools may break temporarily until the package is updated.

How to disable. Remove the cbr-rates entry from your MCP client config and optionally uninstall the package: pipx uninstall atomno-mcp-cbr-rates.

FAQ

Is it officially affiliated with the Bank of Russia?

No, it is an independent, unofficial wrapper around cbr.ru's open endpoints.

Can I get multi-year history in one call?

No, history_rates is capped at 366 days per call, longer periods need repeated calls.
