Connects Muse to Briox accounting. Muse can look up invoices, journal entries and account balances, and create new customers, items and unposted invoices. Drafts stay unposted until you review them in Briox.

Example request: "Show me which invoices are still unpaid in Briox and draft a reminder for the largest one."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Briox to help me. It is a free service with an MCP server at https://briox.usefulapi.io/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
