Read Your Holded Invoices, Contacts, and Leads Through Your Muse

If your small business runs on Holded, your muse can read the books side of it in plain words: who owes what, what is in stock, how much cash sits in your accounts, and where each lead stands.

What it does

The connector adds 9 tools, and every one of them only reads. It can list contacts (customers, suppliers, and leads) with name, tax number, email, and address, and open one in full with billing address, payment terms, and default tax rate. It can list documents by type (invoices, estimates, credit notes, purchase orders) with number, date, contact, total, and payment status, and open one with every line: quantity, price, discount, tax, and payments applied. It can list products and services with code, price, cost, tax rate, and stock level, and list warehouses by name and location. It can list treasury accounts (your bank and cash accounts) with name, account number, and balance: the cash position. For sales, it can list your sales funnels with their stages, and list leads with name, contact, value, stage, and expected close date.

How to use it

1. Start an AnythingMCP account and add the Holded connector.
2. Sign in to Holded, open Settings, then Developers, and generate an API key. Enter it only where the connector asks.
3. In Muse, open Settings, then Connectors, and add a custom connector with the address AnythingMCP gives you. Sign in and approve.
4. Ask for your treasury accounts first, so you know the key works and the balances match what Holded shows.
5. Then ask practical questions, such as which invoices are unpaid, or which leads sit in one funnel stage with a close date this month.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the Holded connector added
• A Holded account and an API key from its developer settings

What to watch for

• The Holded API key belongs to the whole account, not to one person, and it carries full access to every module you pay for. Treat it like a password and enter it only in the connector form.
• The connector uses Holded's older v1 API, not the newer v2 API Holded now documents, so a few newer fields may not appear.
• Nothing can be created, changed, or deleted through these tools. Invoices and follow-ups still happen in Holded, by a person.
• 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.
