Summary generated from the project's README
About Kryptos MCP server
Kryptos connects Claude to your cryptocurrency holdings, transaction history, and accounting data across more than 5,000 exchanges, wallets, and blockchains. This MCP server allows users to manage their financial data through four specific skills: get-started, review-and-reconcile, prepare-tax-year, and crypto-bookkeeping. It is designed for individuals and enterprise users who need to monitor portfolios or sync financial records with professional software.
To use this server, you must install it via Claude Code and sign in using OAuth 2.1 with a Kryptos account. The connection works by interacting with the Kryptos MCP server at mcp.kryptos.io. While the server can read and write data to your workspace, it cannot execute trades, swaps, or withdrawals. For enterprise users, the bookkeeping skill enables synchronization with Xero, QuickBooks, or Softledger by mapping transactions and pushing journals. Security is maintained by only requiring public wallet addresses and never requesting private keys or exchange API credentials during a conversation.
What you can do with it
- 1Onboard new blockchain walletsConnect your blockchain wallets using only your public address to view your initial portfolio.
- 2Reconcile transaction data errorsIdentify and fix issues like missing purchase history, uncategorized transactions, or balance mismatches.
- 3Generate annual tax reportsSummarize a specific tax year and create a formal tax report from your crypto gains.
- 4Sync crypto data to ERP systemsMap transactions with rules and push journals to accounting software like QuickBooks or Xero.

View on GitHubKryptos for Claude
Kryptos brings your crypto portfolio, transaction history, tax figures and accounting ledger into Claude, across 5,000+ exchanges, wallets and blockchains.
This plugin connects Claude to the Kryptos MCP server and adds four skills that guide Claude through common workflows.
What's included
| Component | What it does |
|---|---|
MCP server kryptos (https://mcp.kryptos.io/) |
Tools to read your holdings, transactions, ledgers, tax figures and chart of accounts, and to fix data with your confirmation. |
Skill get-started |
Connect blockchain wallets by public address, wait for the import, and get a first look at the portfolio. |
Skill review-and-reconcile |
Work through the Kryptos Review checks — uncategorised transactions, missing purchase history, missing prices, balance mismatches, high P&L and unidentified addresses — and fix them with you. |
Skill prepare-tax-year |
Check the data and gains are current, summarise a tax year, generate the tax report, and optionally lock the period once filed. |
Skill crypto-bookkeeping |
For Kryptos Enterprise: sync the chart of accounts with Xero, QuickBooks or Softledger, map transactions with rules, and push journals. |
Install
In Claude Code:
/plugin marketplace add Kryptoskatt/ai-plugin
/plugin install kryptos@kryptos
Then run /mcp, choose kryptos and sign in with your Kryptos account.
Authentication and data
- You sign in to Kryptos with OAuth 2.1 and choose one Kryptos workspace. Claude can only act on that workspace, within the permissions your Kryptos role allows. You can revoke access from your Kryptos account at any time.
- The only service this plugin talks to is the Kryptos MCP server at
https://mcp.kryptos.io/, which reads and writes your Kryptos workspace data. The plugin itself contains no scripts, hooks or credentials. - Kryptos never asks for exchange API keys, wallet private keys, seed phrases or passwords in the conversation. Wallets are added by public address only; exchanges are connected in the Kryptos web app.
- No tool can send, swap, withdraw, deposit or trade any asset. The skills ask for your confirmation before changing Kryptos data (labels, prices, contacts, rules, journals), and Claude asks before running a tool that writes.
