<h3>Bringing Crypto P&amp;L Data to AI-driven Workflows&nbsp;</h3>cryptact, the crypto tax platform used by more than 200,000 investors and operated by pafin Inc., today released an MCP server that lets AI assistants such as Claude and ChatGPT pull users' profit-and-loss and portfolio data directly from their cryptact accounts. The server gives users a new way to put their crypto data to work with AI — from analysis to automation.<h3>How It Works</h3>Using Anthropic's open MCP protocol, the cryptact MCP server connects AI assistants directly to a user's cryptact account. Once connected, users can ask questions in plain language and get back profit-and-loss summaries, portfolio data, and transaction histories.<h3>What Users Can Do</h3>At launch, the server offers ten read-only tools. Users can pull realized P&amp;L summaries by fiscal year or asset, search transactions by date or exchange, and check portfolio holdings with current market values and cost basis.For example, a user can ask an AI assistant "Show me my 2025 BTC realized gains," retrieve the annual P&amp;L summary from their cryptact account, and use it for further analysis or automation — all within the AI assistant.<h3>Part of a Broader Push</h3>The MCP server is the second new access channel. On April 2, <a target="_blank" rel="noopener noreferrer" href="https://www.cryptact.com/en/news/cryptact-cli-en">cryptact released a command-line interface (CLI) </a>for developers who prefer terminal workflows. The MCP server broadens the reach further: anyone with an AI assistant can query their cryptact data in plain language — no coding or API calls needed.Future releases will add write capabilities, including transaction editing and transaction history file uploads.<h3>Availability</h3>The MCP server is free for all cryptact users, regardless of plan tier. Setup instructions are available at the <a target="_blank" rel="noopener noreferrer" href="https://support.cryptact.com/hc/en-us/articles/56762747250201">help page</a>.<h3>About pafin Inc.</h3><h4>Services</h4>cryptact — Crypto tax calculations: Simplified.

<h3>Bringing industry-leading crypto tax calculation to automated and agentic workflows</h3>cryptact, the crypto tax platform operated by pafin Inc., today released a command-line interface (CLI) that gives developers and power users direct access to its profit-and-loss calculation engine. The tool works from any terminal and is compatible with AI coding environments such as Claude Code.The cryptact CLI lets users upload exchange files, trigger gain-and-loss calculations, search transaction histories, and export results without leaving the command line. The same commands can be invoked by AI coding tools, trading scripts, and automated workflows.cryptact will also release a <a target="_blank" rel="noopener noreferrer" href="https://modelcontextprotocol.io/docs/getting-started/intro">Model Context Protocol (MCP) server</a> in April 2026, enabling non-technical users to interact with cryptact through chat-based AI assistants.<h3>Background</h3>Accurate cryptocurrency tax reporting demands deep expertise in both blockchain technology and national tax codes. cryptact has spent eight years encoding that expertise into a calculation engine that aggregates data from over 175 sources — including major exchanges and blockchains — and computes realized gains and losses under the tax rules of Japan, Canada, and India.As AI-powered tools become a standard part of everyday workflows, the company has packaged that engine into interfaces that AI tools can call directly — starting with the CLI released today.<h3>How It Works</h3>Users authenticate once via OAuth in their browser, after which the cryptact CLI stores credentials locally.&nbsp;Below are representative examples of what the tool can do.Upload an exchange transaction file:<div style="border-radius:8px;box-shadow:0 4px 16px rgba(0,0,0,0.35);font-family:'SF Mono','Menlo','Consolas','Liberation Mono',monospace;font-size:0.85em;margin:1em 0 1.5em;overflow:hidden;"><div style="background-color:#3a3a3a;line-height:1;padding:8px 14px;">●●●</div><div style="background-color:#1e1e2e;color:#cdd6f4;line-height:1.7;overflow-x:auto;padding:16px 20px;white-space:pre-wrap;">

NFTマーケットプレイス「Blur（ブラー）」での売買の自動損益計算に対応！ 2024年分の確定申告をよりスムーズに

We are pleased to announce the release of our new "Live View" feature. With this update, users can now view their real-time balances across multiple exchanges via API connections.&nbsp;<h4>Development Background</h4>As more investors diversify across multiple exchanges, the need to individually check asset balances has become a notable challenge. Previously, we provided portfolio views based on manually uploaded transaction data. Now, with the Live View feature, we acquire balance information in real-time through API connections with exchanges. This ensures users have an accurate, live view of their holdings, mitigating the issues of data gaps and delays. With this addition, investors who manage assets across several exchanges can now save time and effortlessly oversee their entire portfolio in one unified view. We remain committed to enhancing the user experience continuously.&nbsp;<h4>Key Features</h4>Direct Data Retrieval from ExchangesThrough API connections with over 33 exchanges, this feature provides users with real-time balance data, making asset management more accurate and efficient.* This feature currently supports API-connected exchanges, with plans for ongoing expansion, both within Japan and internationally.*Exchanges supported for API: <a href="https://support.cryptact.com/hc/en-us/articles/33114664105113">https://support.cryptact.com/hc/en-us/articles/33114664105113</a>&nbsp;Consolidated Management Across Multiple ExchangesUsers who previously relied on tools like Excel for balance management can now enjoy automatic, consolidated balance updates from multiple exchanges, eliminating the need for manual data entry.&nbsp;<h4>Future Outlook</h4>With this launch, we plan to build a historical repository of balance data, enabling users to view asset performance and past balance history in JPY. Additionally, this feature is expected to enhance the profit and loss calculation process. Currently, profit and loss calculations rely on user-uploaded transaction histories; however, with this feature, actual balances retrieved directly from exchanges can soon be cross-checked against uploaded data, with adjustments for any discrepancies under consideration. This improvement will lead to even more precise profit and loss calculations, making the investment process smoother for users.We also plan to expand the list of API-connected domestic exchanges to broaden the feature’s user base.cryptact will continue to keep pace with the evolving cryptocurrency market, enhancing user convenience through continuous feature improvements.&nbsp;&nbsp;

Cryptact launched new "Live View" feature. With this update, users can now access their most up-to-date cryptocurrency balance across multiple exchanges.
