Two ways to use Hellobell

Whether you're a standalone business or a software platform, Bell works with your data.

For businesses

Enter your info and go live

No engineering required. Sign up, enter your hours, services, and FAQs — Bell uses that to answer calls, texts, and chats for your business.

1. Sign up and enter your business details
2. Customize Bell's voice, tone, and rules
3. Forward your phone number and go live

Want live data? You can optionally connect an MCP server later.

For software platforms

One integration, every customer

Build one MCP server that connects your platform to Bell. Bell handles calls for all your managed accounts with per-tenant data scoping — like Stripe Connect for voice.

1. Build your MCP server (we provide templates)
2. Create managed accounts via API or dashboard
3. Each account gets its own number, voice, and config

Per-tenant auth scoping ensures each account only accesses its own data.

Platform architecture

One MCP server serves all your customers. Bell scopes every request to the right tenant.

Your Customers

You build one MCP server that exposes your platform's capabilities. Bell resolves the tenant from the incoming phone number and scopes every tool call to the right account — your customers' data stays isolated.

What is MCP?

Model Context Protocol (MCP) is an open standard that lets AI systems discover and use your software's capabilities. You expose tools like "check availability" or "book appointment" — Bell calls them in real time during customer conversations.

For platforms, your MCP server handles requests for all managed accounts. Bell passes a tenant header with each request so your server knows which business to query.

Your MCP server lives in your codebase. You control what Bell can access.

Three channels, one brain

Voice

Hellobell answers calls with natural conversation. It checks real availability, books appointments, and answers questions — all from your data.

SMS

Two-way text messaging that handles booking confirmations, rescheduling, and common questions.

Web Chat

Embed a chat widget on your platform. Same AI, same data, instant responses for your customers.

Your data stays yours

Zero database access

Hellobell never connects to your database directly. All data flows through your MCP server.

Per-tenant auth

Authentication is derived from channel context (phone number, API key) — never from AI model output.

You control the tools

Your MCP server defines exactly what Hellobell can do. Add or remove capabilities any time.
