Broad access

Why this level

  • The T-Invest token gives access to a real brokerage account, and a leak exposes the owner's data
  • With ENABLE_PORTFOLIO on, the server reads real portfolio and account operations, even though there are no write methods in the code

How we review

Broad accessThe tool can change data, run commands or handle secrets.

  • The T-Invest token gives access to a real brokerage account, and a leak exposes the owner's data
  • With ENABLE_PORTFOLIO on, the server reads real portfolio and account operations, even though there are no write methods in the code

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

What it does

A Python server provides 9 tools and picks the data source itself: without a token, quotes, candles, a screener, indices and coupons work through MOEX ISS with a 15-minute delay; with a T-Bank Invest token, real-time quotes, order book, dividends are added, and, if ENABLE_PORTFOLIO is explicitly set, account portfolio and operations too. Every response follows one contract with a source field, a stale flag for non-live data, and an explicit delay figure. The token is read-only, never appears in logs or responses, and account numbers are masked. A local SQLite cache has its own TTL per data type: the instrument directory for a day, closed-day candles indefinitely, quotes for 15 seconds.

Who it is for. For private investors and developers who want MOEX quotes and portfolio data in one format with no risk of an accidental trade.

Good fit when

  • You need MOEX quotes and candles with no token, even with a 15-minute delay
  • You need a screener for securities filtered by trading mode
  • You need T-Bank Invest portfolio and operations alongside market data, by explicitly enabling ENABLE_PORTFOLIO

Not a fit when

  • You need trading or order cancellation: there are no order-placement methods in the code at all
  • You need market data with no Windows-specific instructions: the README and path examples target Windows, though the stack is cross-platform
  • You need indicators, backtesting or technical analysis: the server only returns raw data

Example request

Show Sberbank's quote and this week's candles, and if the portfolio is available, compare its return with the MOEX index

Transport
stdio
Authentication
key is optional

Environment variables

TINVEST_TOKEN secret
Read-only T-Bank Invest token; without it the server uses MOEX ISS only
ENABLE_PORTFOLIO
Defaults to false; enables registering get_portfolio and get_operations
TINVEST_SANDBOX
Use the T-Bank Invest sandbox for development

Limitations

Portfolio and operations tools are not registered until ENABLE_PORTFOLIO is set to true; by default the server only sees the market. Without a token, data comes from MOEX ISS with a 15-minute delay. T-Bank Invest's TLS certificate is issued by a Russian certification authority, and a verification error on Windows requires installing the Ministry of Digital Development root certificate. The README and instructions target Windows (PowerShell, C:\ paths), though the code itself is cross-platform.

How to disable. Remove the market entry from claude_desktop_config.json and delete the .env file with the token; to disable the portfolio, just remove ENABLE_PORTFOLIO.

FAQ

Do I need a token for basic use?

No, without a token quotes, candles, a screener, indices and coupons already work through MOEX ISS, just with a 15-minute delay.

Could the server place an order?

No, there are no order-placement methods in the code at all, only reading market data and, if enabled, the portfolio.
