Developer docs

Connect your own tools.

An API and an MCP server, available on request.

API

For your developer.

Plain web requests that read and update your Harmonia records. Use it from your own code, or from any tool that can send a web request, like Zapier or n8n.

MCP

For your AI assistant.

Plug it into Claude, ChatGPT, or any assistant that supports MCP. Then ask in plain words: “Who called today?” “Who still owes me?”

What it can do
What you see in your dashboard, from your own tools.
Calls

Every call

Who called, the summary, the transcript, and the recording.

Customers

Every customer

Find a customer, see their history, and add a note.

Quotes & jobs

Your calendar

Open quotes and the day’s jobs. Book a job into the calendar.

Payments

Your money

Invoices, what’s been paid, and who still owes.

Through MCP, anything that books a job, sends something, or calls someone asks you for a yes first.

How to get access
Three steps, and we do the second one.
Ask

Tell us what you want to connect

Which tool, and what you want it to do. Book a call, or reply to any email from us.

Set up

We turn it on for your business

You get a private key. It opens your business and nothing else.

Connect

Paste the key into your tool

That’s the setup. Ask us any time and we switch the key off.

The rules
What you agree to when you use it.
  • On request. We turn access on by hand, one business at a time, and we can say no.
  • Your business only. A key opens one business’s records: yours. It can never see anyone else’s.
  • Keep the key secret. It works like a password. If it leaks, tell us and we replace it.
  • Only contact people who asked. Don’t use it to call or text anyone who hasn’t asked to hear from you. The laws on calls and texts still apply, and they apply to you.
  • Your data is yours. Export it whenever you like. Don’t resell access, and don’t use it to build a product like ours.
  • Fair use. Each key has a request limit sized for one business. If you need more, ask.
  • Records, not the recipe. It opens your records and actions. It doesn’t open the instructions, voices, or models behind your digital employee.
  • It can change. It’s new. We’ll tell you before we change or remove anything you use, and we can switch off a key that’s being misused.

Using the API or MCP means you agree to our Terms and Privacy Policy.
