What it does

The project offers three ways to work with Moscow Exchange data on shares and bonds. The command line `python -m moex_iss` runs `quote`, `search`, `history`, `candles` and `bondization` with table or CSV output, for example `python -m moex_iss quote SBER` or `python -m moex_iss history SU26238RMFS4 --from 2025-01-01 --format csv --out ofz.csv`. The Python class `MoexISS` gives the same calls in code and `mcp_server.py` connects them to Claude Desktop or Cowork. The code is written on the Python 3.10+ standard library only and works with no API key. The repository carries a skill `.claude/skills/moex-iss/SKILL.md` that sends the agent to read `AGENTS.md` with a task to method table and data interpretation rules instead of writing requests to iss.moex.com by hand. The documents `docs/ROUTES.md` and `docs/ROUTES_STATUS.md` keep a catalog of verified routes and an automatic report on all 255 routes of the ISS reference. The `scripts/verify_data.py` script self-checks by recomputing accrued interest and yield.

Who it is for. Analysts and private investors who study bonds (OFZ, corporate), the yield curve and the IMOEX composition through Claude Desktop or from the command line.

Limitations

The project is unofficial and not affiliated with PJSC Moscow Exchange, the data belongs to the exchange and its use is governed by exchange terms. Without a subscription quotes are delayed by about 15 minutes and the order book, dividends and CCI indicators are unavailable. Bond prices are expressed in percent of face value.

Python 3.10 or newer is required. Connecting to Claude Desktop is done by editing `claude_desktop_config.json` by hand: the command points to `python` and the path to `mcp_server.py`. Live tests `python -m unittest discover -s tests -v` call the exchange API. The project is not investment advice.

How to disable. Remove the `moex-iss` entry from `claude_desktop_config.json` and the project directory, and take the skill out of `.claude/skills`.

README in short
