Best Claude connectors for small business owners

How do Claude connectors work, and what do you consent to?

A connector is an MCP server that gives Claude a short, fixed list of actions inside another product. You add one from the directory under Customize, then Connectors, or add a custom connector by pasting its URL.

Consent has two layers. You sign in to the product through OAuth and see what the connector can reach; Claude never sees your password. Then Claude asks before it runs a tool, and you allow once, allow always, or decline. Disconnecting in settings cuts access at once; the agent security page explains the model as we apply it.

Finance and funding: BusinessLoanBroker.ai

This one is ours, so read it with that in mind. The BusinessLoanBroker.ai connector lets Claude apply for a business loan on your behalf: you share bank statements, tax returns and financials, and Claude extracts the numbers, fills the application, tells you what is missing, matches lenders in every category and submits only when you approve.

What to watch: it cannot accept an offer or sign anything, and it cannot make a weak file strong. It is free for your business; lenders pay us when a loan funds, and we are paid the same whichever lender you choose. Setup is on the Claude page; using AI to get a business loan explains the process.

Accounting: QuickBooks and Xero

QuickBooks. Intuit's connector lets Claude read your profit and loss, balance sheet and aging reports, and draft invoices, estimates and payment reminders from your own books. Let it read freely and ask before it creates or sends anything. Your QuickBooks subscription is the cost; the connector is free.

Xero. Xero publishes an MCP server covering contacts, invoices, bank transactions and reports. Check the Claude connector directory first; if Xero is not listed, its server can be added as a custom connector, though that setup is more technical.

Payments and banking data: Stripe and Plaid based tools

Stripe. Stripe publishes an MCP server that lets Claude look up customers, payments, subscriptions and your balance, and create products, invoices and payment links. A refund or a cancellation has money consequences, so keep those on ask every time. Stripe's normal fees apply; the connector adds nothing.

Plaid based tools. You will not usually connect Plaid itself. Plaid is the plumbing that cash flow, bookkeeping and lending apps use to read your bank transactions with your consent. Connect one of those apps or your accounting software and let Claude read from there. Lenders still want the statements themselves, so keep the PDFs.

Documents: Google Drive and Notion

Google Drive. The Google Drive connector lets Claude search your Drive and read documents, sheets and PDFs you can access, so you can ask it to find last year's lease and the renewal date, or point it at a folder of statements. It reads; it does not reorganize your files.

Notion. The Notion connector lets Claude search, read and create pages and update database entries, a reasonable home for procedures, a vendor list or a simple pipeline. Both cost nothing beyond the Google or Notion plan you have.

Email and calendar: Gmail and Google Calendar

Gmail. The Gmail connector lets Claude search and read your mail and draft replies. Whether it can also send depends on the permissions you grant, so start with search and draft. Your inbox holds everything, so connect only the account you intend.

Google Calendar. The Calendar connector lets Claude read your schedule and create or update events, so asking it to find an hour this week for the bank call and book it works. Both come with a Google account and a paid Claude plan, and both use an OAuth sign in you can revoke from your Google security settings at any time.

CRM, e signature and projects: HubSpot, DocuSign, Asana and Linear

HubSpot. The HubSpot connector lets Claude read contacts, companies and deals and add notes and tasks, so you can ask what changed in the pipeline this week without opening the CRM. DocuSign. The DocuSign connector lets Claude list agreements, check who has not signed, send reminders and send a document from a template. Sending an envelope is a real action, so keep it on ask every time.

Asana and Linear. Asana lets Claude create and update tasks and projects and report what is overdue; Linear does the same for software teams. With every connector here, start with one weekly job, run it with Claude asking before each action for a month, then widen.
