The best Claude connectors for a small business are the ones that map to jobs you already do: LedgerMCP for the books, Google Workspace or Microsoft 365 for files and email, Slack for communication, Stripe or PayPal for payments, and Notion or Atlassian for project tracking. As of August 2026 Claude’s directory lists well over fifty connectors, so this roundup is organized by job, not by app, with honest notes on what each one actually does. If connectors are new to you, start with what Claude connectors are; the short version is that each one is an MCP server behind a one-click Connect button.
Books and accounting: LedgerMCP (and when QuickBooks fits)
Bookkeeping is the job where a connector changes the most, because the work is repetitive, rule-bound, and exactly what an assistant is good at when it has real tools. LedgerMCP is a free double-entry ledger built for this: 65 MCP tools, 25 read and 40 write, so Claude does not just answer questions about your books, it keeps them: imports bank CSVs, categorizes, splits, reconciles, and runs the P&L, with every write reversible and read-only keys available. The honest limits: LedgerMCP has no built-in AI (Claude is the intelligence; the ledger is the engine), and while the software is free with unlimited books, the bank feeds are the paid part, Plaid tiers at $9, $19, or $79 a month. The full workflow is on the Claude bookkeeping page.
The alternative is Intuit’s QuickBooks connector, which arrived with Anthropic’s Claude for Small Business plan in May 2026. It is read-and-query oriented, US-only, and requires a paid QuickBooks Online subscription ($38 to $275 a month). If you already live in QuickBooks and mostly want to ask questions of the file, it is a reasonable add-on. If you want Claude to do the bookkeeping, it is not the shape for that; our post on whether Claude can do bookkeeping walks through the difference.
Files and documents: Google Drive, Microsoft 365, Notion
The most-used connectors in the directory are the file suites, and for good reason: most of a small business lives in documents. The Google Workspace connectors give Claude access to Drive, Docs, Sheets, Gmail, and Calendar; Microsoft 365 covers the equivalent on the other side. Pick whichever suite you already run, not both. Notion’s connector is the strongest pick if your operating docs, wikis, and SOPs live there, since Claude can search and work with pages directly. Box and Dropbox connectors also exist as of August 2026 for businesses on those platforms. The job these do is retrieval and drafting: find the contract, summarize the folder, draft the doc where it belongs.
Communication: Gmail and Slack
Email is where connector access starts paying for itself daily: with Gmail connected (via the Google Workspace connector), Claude can search your inbox, summarize threads, and draft replies with the actual history in front of it. Slack’s connector does the same for internal communication: catch up on a channel, pull the decision out of a long thread, draft the announcement. These are also the connectors where permission thinking matters most, because email is the most sensitive system most businesses have. Grant them deliberately, and remember that Claude asks before consequential actions rather than sending things on its own.
Payments: Stripe and PayPal
Stripe’s connector, in the directory since its 2025 launch, lets Claude look at your payments data: find a charge, check on a customer, summarize the week. PayPal’s connector arrived alongside the small business push. These pair naturally with a books connector: the payments tool answers "what happened in the processor," the ledger records what it means. Worth saying plainly: payments connectors are for visibility, not for wiring money around, and that is the right boundary for an assistant.
Projects and design: Atlassian, Asana, Canva, Figma
For project tracking, the Atlassian connector (Jira and Confluence) and Asana’s connector let Claude query and update work items: what shipped, what is blocked, write the standup summary. On the design side, Canva and Figma are among the directory’s most popular connectors as of mid-2026; Canva’s is genuinely useful for a small business that produces its own marketing, since Claude can work with designs rather than just describe them. These are nice-to-haves for most owners: wire them up when the job shows up, not before.
How to choose: two or three, by job
Every connector you add is standing access to a system, so the right number is small. A sensible starter set for most small businesses: your file-and-email suite (Google Workspace or Microsoft 365), your communication tool, and your books. That set covers the daily loop: find it, discuss it, record it. Bookkeeping is worth wiring early precisely because it is the job owners most want off their plate; the full picture of using Claude as your bookkeeper is in Claude for small business bookkeeping. Then let the rest of the directory earn its way in one real job at a time.
Quick answers
What is the best Claude connector for bookkeeping?
For keeping the books, LedgerMCP: a free double-entry ledger whose 65 MCP tools let Claude import, categorize, reconcile, and report directly, with unlimited books. If you already pay for QuickBooks Online in the US, the QuickBooks connector is the read-and-query alternative.
Are Claude connectors free to use?
Adding a connector costs nothing. The service behind it may not be free: the QuickBooks connector expects a paid QuickBooks Online subscription, while LedgerMCP’s software is free and only its optional Plaid bank feeds are paid, from $9 a month.
How many connectors should a small business add?
Start with two or three that map to real jobs: usually your file and email suite, your communication tool, and your books. Every connector is standing access to a system, so add them for jobs you have, not apps you recognize.
Do I need the Claude for Small Business plan to use connectors?
No. The connectors directory is available to Claude users generally. As of August 2026 a few connectors arrived through the Claude for Small Business plan, most notably QuickBooks, which is also US-only and tied to a paid QuickBooks subscription.
