Parrot — give any AI a real phone

Giving your AI agent those abilities

It makes calls. It answers calls.

Outbound or inbound — the same bridge, assistants, and guardrails work both directions.

Outbound

Parrot places the call

Claude Code dials any number on your own SIM — presses DTMF keys to work through IVR menus, waits on hold, talks to a real human, and hands back a structured answer.

Inbound

Parrot answers the call

Calls to your number get picked up and screened by the agent — it answers questions, takes a message, or rings you through when it matters.

Real calls, not VoIP

Calls ride your phone's own SIM and carrier over Bluetooth HFP. Any number that can be dialed can be reached — IVR menus, hold music, real humans.

You hold the guardrails

Read-only by default. Blocked number ranges, never-say lists, call caps, and per-agent scopes are all enforced server-side — never trusted to the caller.

How it works

A headphone, designed for AI.

To your phone it's an ordinary Bluetooth headset. To any AI agent, it's a real phone line — bridged through your browser.

Virtual Bluetooth

One pairing, and your SIM is on tap

To your phone, the USB board looks like an ordinary Bluetooth headset — so it hands over the call's mic and speaker. Parrot carries that audio through your browser to Parrot Cloud, where it becomes a realtime voice that can speak and hear on both inbound and outbound calls.

Pair once. The phone remembers the board like any headset.
No SIM swap, no app. Your existing number places the call.
Hang up anytime. Close the tab and the audio link drops instantly.

Get started

Live in four steps, all in the browser

No app, no software to install. A USB board, your phone, and Chrome is the whole setup.

STEP 01

Flash from the cloud

Plug the ESP32 board into your laptop. Click Flash and Parrot streams the latest bridge firmware straight from the cloud onto the board — in the browser, no toolchain or IDE.

● ~30s · cloud → board in Chrome

Where do I get the board? ›

STEP 02

Connect over Web Serial

Hit Connect a board and pick the port in Chrome's Web Serial prompt. The tab becomes your bridge host — keep it open and the call's audio flows through it.

● one click · Web Serial

STEP 03

Pair your phone

On your phone's Bluetooth, tap the board — it shows up as a headset. One pairing links your SIM, and the call's audio, to the bridge.

STEP 04

Use Parrot Cloud

In the Parrot Cloud console, define assistants and guardrails — it can already answer & place calls. Optionally mint an MCP key so your agents can trigger outbound calls too.

Configure once

Define the call. Call it by name.

Open either tab to see what a assistant is and what MCP is — how you define them, and why each one matters.

Assistant MCP scn_instock

What's an assistant?A assistant is a reusable call recipe — the goal, the questions, what to extract, the voice, and the guardrails. Define it once in the console; Parrot follows it on every call and hands back a structured result. Why you need it: consistent, on-policy calls without re-explaining the task each time.

Objective · the prompt the agent follows

Call the store and find out whether {{item}} is in stock today and its price. Don't place an order or share personal details. End politely once you have the answer.

What's MCP?MCP (Model Context Protocol) is the standard way AI agents connect to tools. Point any MCP client at your endpoint and it gets one place_call tool — so an agent can trigger a call by assistant name, on demand. Why you need it: only for agent-initiated outbound — inbound & scheduled calls run from assistants alone, no MCP required.

Built for Claude Code

Let Claude Code use your phone
to make and receive calls.

It's a standard remote MCP server with one tool — place_call. Add it to Claude Code and your agent dials real numbers on the number you already own, works the call, and hands back a structured result.
