    Questions people ask

    What does the Breezing connector do in Claude?

    Breezing is crypto accounting software for accountants, finance teams and Web3 businesses. It imports transactions from more than 70 blockchains and exchanges, prices them in your base currency, computes cost basis and net gain or loss, and books journals to Xero, QuickBooks Online and Bexio. The Breezing connector gives Claude the same Public API your team uses behind the dashboard. Claude can list companies, wallets, transactions, balances, contacts, rules, reports and tasks. It can categorize transactions by assigning accounts from your chart of accounts, create and apply rules for recurring patterns, group trades and internal transfers, lock closed periods, start balance and net gain or loss calculations, generate token and account reports, and trigger the sync to your accounting platform. What it never does: the connector cannot move funds. Breezing reads blockchain and exchange data through public addresses and read-only exchange keys, and it has no ability to sign transactions or transfer assets. It also never deletes records. Destructive actions stay in the Breezing dashboard. Every tool that changes data is flagged, so Claude asks you to confirm before it writes. Access uses a Breezing API key you create in your company settings, scoped to the companies you choose with read or write permission per company, and you can revoke it at any time. Setup: sign in to Breezing, create an API key under Company settings, then add the Breezing connector in Claude and paste the key on the authorization page. Documentation: https://learn.breezing.io/mcp/introduction

    Is the Breezing connector official?

    It is made by Breezing SA and carries the Anthropic verified mark in Anthropic’s directory. This site is independent and lists it from the official directory.

    What is the Breezing MCP server URL?

    https://mcp.breezing.io/mcp. It is a remote MCP server hosted at mcp.breezing.io. Paste it into Claude as a custom connector, or add it to Claude Code with: claude mcp add --transport http breezing https://mcp.breezing.io/mcp

    How do I add Breezing to Claude Code?

    Run "claude mcp add --transport http breezing https://mcp.breezing.io/mcp" in your terminal, then start Claude Code, type /mcp, choose breezing and sign in to Breezing. Add "--scope user" to make it available in every project.

    Do I need a Breezing account?

    Yes. You sign in to Breezing when you connect it, and Claude works through that account.

    Can Claude change or delete my Breezing data?

    Judging by tool names, 23 of its 60 tools can change data. The other 22 only read. In Claude you can choose, per tool, whether Claude must ask before using it.
