`mcp-cbr-rates` is part of the [atomno](https://atomno-labs.ru) family of MCP
servers focused on the Russian fintech ecosystem. It is fully open-source,
requires no API keys, and is built on top of the official public CBR
endpoints.

## Features
- Five high-quality MCP tools, each with a strict Pydantic schema:
`get_rate`, `history_rates`, `key_rate`, `inflation`, `statistics`.
- Built-in TTL (Time-To-Live) cache: 1 hour for daily quotes, 24 hours for
historical series, to be polite to the source.
- Async ``httpx`` transport with automatic retries on 5xx errors.
- Safe XML parsing via ``defusedxml``.
- 50+ unit tests with ``respx``-mocked HTTP, ≥80 % coverage.
- No secrets, no telemetry, no third-party trackers.

## Quick start
### Install from PyPI (recommended)
```bash
pipx install atomno-mcp-cbr-rates
atomno-mcp-cbr-rates # starts the MCP server over stdio
```
Or with `uv`:
```bash
uv tool install atomno-mcp-cbr-rates
```
### Install from source
```bash
git clone https://github.com/atomno-mcp/mcp-cbr-rates.git
cd mcp-cbr-rates
pip install -e .
atomno-mcp-cbr-rates # starts the MCP server over stdio
```
### Use with Cursor
Add the following to `.cursor/mcp.json` (or your global `~/.cursor/mcp.json`):
```json
{
"mcpServers": {
"cbr-rates": {
"command": "atomno-mcp-cbr-rates"
}
}
}
```
### Use with Claude Desktop
Add to `claude_desktop_config.json`:
```json
{
"mcpServers": {
"cbr-rates": {
"command": "atomno-mcp-cbr-rates"
}
}
}
```
On Windows the config lives at
`%APPDATA%\Claude\claude_desktop_config.json`; on macOS at
`~/Library/Application Support/Claude/claude_desktop_config.json`.
### Use with Claude Code
```bash
claude mcp add cbr-rates -- atomno-mcp-cbr-rates
```

## Tools
| Name | Inputs | Returns |
|---|---|---|
| `get_rate` | `char_code: str`, `on_date?: date` | `CurrencyRate` — single quote on the given (or latest) date |
| `history_rates` | `char_code: str`, `date_from: date`, `date_to: date` | `HistoryRates` — series of daily quotes |
| `key_rate` | `date_from?: date`, `date_to?: date` | `KeyRateHistory` — CBR key-rate series |
| `inflation` | `year_from?: int`, `year_to?: int` | `InflationData` — monthly year-over-year CPI in percent |
| `statistics` | _(none)_ | `MacroSnapshot` — combined dashboard: key rate + USD/EUR/CNY + inflation |
Examples in plain English:
> *"What was the official EUR rate on April 25, 2024?"*
> Tool: `get_rate(char_code="EUR", on_date="2024-04-25")`
> *"Plot the daily USD-RUB rate over the last 90 days."*
> Tool: `history_rates(char_code="USD", date_from=..., date_to=...)`
> *"Give me the latest key rate, USD/EUR/CNY, and inflation in one go."*
> Tool: `statistics()`
The `history_rates` window is capped at 366 days; for longer periods, call
the tool repeatedly.

## Configuration
All settings are optional and read from environment variables:
| Variable | Default | Description |
|---|---|---|
| `MCP_CBR_HTTP_TIMEOUT` | `15` | HTTP timeout in seconds for CBR calls. |
| `MCP_CBR_CACHE_DAILY_TTL` | `3600` | Cache TTL for daily quotes (seconds). |
| `MCP_CBR_CACHE_HISTORY_TTL` | `86400` | Cache TTL for historical series and SOAP responses. |
| `MCP_CBR_LOG_LEVEL` | `INFO` | Standard Python log level. |
Legacy `CBR_*` names are still accepted for compatibility, but new configs should use `MCP_CBR_*`.
There are no API keys to configure — all CBR endpoints used here are public.
