Frequently asked questions

Common questions and answers from our users.

What is cryptact's AI integration feature?
cryptact's AI integration lets you operate your crypto transaction data in natural language from AI assistants like Claude and ChatGPT. We offer two formats — the MCP Server (conversational) and the CLI (command-line) — so you can complete P&L summaries, transaction search and editing, and recalculations through conversation with AI. Supports 177+ exchanges and blockchains, and 29,207 cryptocurrencies.
What is MCP? Can I use it for crypto tax filing?
MCP (Model Context Protocol) is an open standard that connects AI assistants to external services. With the cryptact MCP server, you can use AI assistants like Claude or ChatGPT to pull your P&L data, portfolio, and transaction history directly — just by asking in plain language. For example, you can ask "What was my BTC realized P&L in 2025?" and instantly get the information you need for tax filing, making it a practical tool for managing your crypto taxes.
Is the cryptact MCP server free to use?
Yes, it's free for all cryptact users on every plan, including the Free plan. There are no additional charges. If you already have a cryptact account, you can connect to the MCP server using your existing credentials — no extra setup or subscription required.

Is it safe to send my crypto transaction data to an AI?
cryptact's MCP server securely connects to your cryptact account via OAuth authentication. Your credentials are never passed directly to the AI assistant, and data is read or written only based on your instructions. Please note that how the AI assistant handles your data (including its use for training) is governed by the policies of the AI service you are using (such as Claude or ChatGPT), so we recommend also reviewing the privacy settings of each service.
Can I estimate my crypto taxes using data from the MCP?
The data you receive through the MCP server — P&L summaries, portfolio positions, and transaction history — is calculated by the cryptact engine. The AI assistant serves as a convenient way to query and organize those results in natural language. You can quickly check things like "What's my realized P&L this year?" or "Which assets have gains?" to make tax filing preparation much faster.
