Kryptos — Claude Code MCP server: features and setup
Connect Claude Code to Kryptos portfolio data to inspect transactions, tax figures and accounting records. Useful for reconciling crypto activity and preparing a tax report.
claude mcp add --transport http kryptos https://mcp.kryptos.io/What Kryptos 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.
What it helps with
- inspect portfolio holdings and transaction history
- find uncategorised transactions or missing prices
- check balance mismatches and unidentified addresses
- prepare a tax report for a tax year
- map transactions to ledger accounts in Kryptos Enterprise
Example prompts for the agent
- Show the assets and recent transactions in my Kryptos workspace.
- Review my transactions for reconciliation issues and ask before saving any changes.
- Check the data for this tax year and prepare a tax report.
