Rates, key rate and inflation usually arrive through a data vendor with a key and a quota. These come from the central bank's own endpoints with neither, and the snapshot tool answers where things stand in a single call.
A Python MCP server over the Central Bank of Russia's public endpoints, covering currency quotes, the key rate, CPI inflation and a combined macro snapshot. Five tools, open source, no API key.
- The official CBR rate for one currency on a given date, or the latest published one
- A rate series for one currency between two dates inclusive
- The CBR key rate as a time series over the range you ask for
- Monthly year-over-year CPI inflation as published by CBR
- A compact macro snapshot in one call: latest key rate, USD, EUR and CNY rates, and the latest YoY inflation with the period it covers
- A TTL cache — one hour for daily quotes, a full day for historical series — so repeat questions do not hit the source again
A recent Python. Install with pipx install atomno-mcp-cbr-rates or uv tool install, then run atomno-mcp-cbr-rates, which speaks MCP over stdio. No API key and no account: it reads the official public CBR endpoints. Historical ranges are capped by the server.
One command — uvx atomno-mcp-cbr-rates
