What's MCP, and why use Tugger's?

MCP is how AI assistants connect to business data.

It stands for Model Context Protocol, and it's the standard Claude, ChatGPT and Gemini all use. Tugger's MCP is the secure route between your assistant and your BigChange data. One connection covers every app you've connected to Tugger.

Ask anything.Break nothing.

Why's Tugger's MCP read‑only?

Because your AI assistant should answer questions about BigChange, not make changes to it.

Tugger reads from BigChange. It never writes back. So nothing an assistant does can change, delete or create a record.

Why use Tugger's MCP?

  • One question, every appAsk across BigChange, Xero, HubSpot and the rest in a single conversation. Tugger handles the joins.
  • AI that understands BigChangeYour data arrives structured and described, so your assistant knows what each record is and how they fit together.
  • As much history as you wantPick how far back to go when you connect BigChange. Trends and year-on-year comparisons are there to ask about.
  • Your choice of assistantClaude today, something else tomorrow. Same connection, same data, same controls.

What can AI see of your BigChange data?

Only what you allow.

AI privacy controls, built in

BigChange holds more than jobs. Customer phone numbers. Notes somebody typed three years ago. Customer email addresses. You decide, category by category, what an AI assistant gets to see.

  • Hidden means hiddenSet a category to Hidden and it's withheld inside Tugger before the answer leaves. The AI can't filter, count or total on it either.
  • Staff and customers, set separatelyKeep staff names visible for scheduling questions while customer details stay hidden. Or the reverse.
  • Different rules where you need themSet rules for your whole account, then override them for BigChange, a single connection or an individual user.

What Tugger customers say

Don't just take our word for it.

One of our customers wants a monthly evaluation pack built from thousands of Simpro jobs. It used to take a full day. Now our data reaches Claude through Tugger and the pack comes back in ten minutes, exactly how they want it.

With Tugger we are now utilising Claude AI and Cowork to carry out analysis that was never before available to us. This has been a paradigm shift in speed and accuracy of management decision making in our business.
Jeff Smith
Partner & Director of Digital Disruption · Envirotech Group
Batch invoicing and reporting used to eat hours of admin time each week, chasing details back and forth between Simpro and our spreadsheets. Now it runs on its own, and because Tugger guides the AI to the right figures, I can trust what comes out.

Can I control what AI sees in my BigChange data?

Yes. Tugger's AI privacy controls let an administrator set each category of personal data to Visible or Hidden, separately for staff and for customers. Anything hidden is withheld inside Tugger before the answer leaves, and every AI call is recorded.
