PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Before you install

Common questions

Is Kryptos safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 34 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Kryptos 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

ComponentWhat 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-startedConnect blockchain wallets by public address, wait for the import, and get a first look at the portfolio.
Skill review-and-reconcileWork 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-yearCheck the data and gains are current, summarise a tax year, generate the tax report, and optionally lock the period once filed.
Skill crypto-bookkeepingFor 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.
