Read Your Mercury Business Banking Through Your Muse

If your business banks with Mercury, your muse can read your accounts, balances, and transactions in plain words, and it works with a read-only token that cannot send money.

What it does

Mercury is business banking with checking and savings accounts, cards, and Treasury accounts. Through a connector with 22 tools, your muse can list accounts with available and current balances, and list transactions for one account or across all accounts, with counterparty, note, category, and card used. It can list your debit and credit cards with spend limits, give you monthly statement download links, and list saved payment recipients without bank details. It can read Treasury accounts, list credit accounts, show who has access, and their role, and list payment requests waiting for approval. Account and card numbers are removed from every answer. The connector has no tool for payments or transfers. The tools that freeze a card or add a note to a transaction are installed switched off.

How to use it

1. Start an AnythingMCP workspace and install the Mercury connector.
2. In Mercury, open Settings, then Tokens, create an API token, and choose Read Only. Copy the token into the connector where it asks for MERCURY_API_TOKEN.
3. In Muse, open Settings, then Connectors, and add a custom connector with the MCP server address AnythingMCP gives you. Sign in and approve.
4. Check the setup by asking the muse to name your organization and list your accounts.
5. Ask the real questions, such as what went out over 5,000 dollars in the last 30 days, or which payment requests are waiting for approval.

What you need

• A Muse account that can add custom connectors
• A Mercury business banking account
• An AnythingMCP account with the Mercury connector added
• A Mercury Read Only API token, never a Read and Write token

What to watch for

• Use the Read Only token only. A Read and Write token can send money, and this guide does not need it. Mercury shows a token only once, and deletes tokens unused for 45 days, so you may need to make a new one later.
• Bank data is sensitive company data. Share this connector only with people allowed to see balances and transactions, and disconnect it when it is no longer needed.
• The muse can list a payment request, but it cannot create, approve, or cancel one. Approvals still happen inside Mercury.
• This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
