## What it does

The MCP server gives Claude access to assets, transactions, tax figures and ledger data in one selected Kryptos workspace. Its skills can help connect a wallet by public address, review data issues and prepare a report for a tax year. Accounting features require Kryptos Enterprise.

Sign-in uses OAuth 2.1 and a Kryptos account; access follows the user’s role and applies to the selected workspace. Claude asks before writing changes, and its tools cannot move or trade assets. Wallet private keys and exchange API keys are not needed; exchanges are connected through the Kryptos web app.
