Copilot Studio and VS Code: Add Phone Calls With OsmO

Short answer: We found no way to add your own connectors to the consumer Copilot app, but two Microsoft tools can take them: Copilot Studio agents and GitHub Copilot in VS Code. Both take OsmO as a remote MCP server with OAuth.

Copilot Studio: Tools → Add a tool → New tool → Model Context Protocol.

VS Code: MCP: Add Server or .vscode/mcp.json.

We found no way to add OsmO to the consumer Copilot app.

Ask it to callOsmO calls, talks, and tells you what was said.

The full guide

Before you start

Copilot Studio access, or VS Code with GitHub Copilot.
A mobile number from the US, Canada, the UK or Australia (India also works) to receive a sign-in code.
Nothing to pay: you start with 50 free credits.

Connect OsmO to Copilot

In Copilot Studio, open your agent and choose Tools → Add a tool → New tool → Model Context Protocol.
Enter https://api.getosmo.app/mcp as the server URL.
Pick OAuth 2.0 with dynamic discovery; OsmO supports dynamic client registration.
Publish the agent. The first time it calls, sign in to OsmO with your mobile number and the texted code.

GitHub Copilot in VS Code

Run MCP: Add Server from the command palette, choose HTTP and paste the URL, or add "osmo": {"type": "http", "url": "https://api.getosmo.app/mcp"} under servers in .vscode/mcp.json. VS Code runs the sign-in for you.

GitHub's cloud coding agent does not support remote MCP servers that need OAuth, so use OsmO from the editor.

Make a first test call

Make your first call a low-stakes one, such as asking a shop for its opening hours. You will see how your AI app confirms the call, how long a call takes and what the answer looks like, before you send it on anything that matters.

If something goes wrong

Common messages and what they mean
What you see	What it means	What to do
"You've used your free OsmO credits"	Not enough credits left for this request (each call needs 3)	Ask for fewer calls at once, or keep calling from the OsmO app: getosmo.app/app
"OsmO can call listed businesses and toll-free numbers"	The number is not a listed business, a toll-free line or one of your saved contacts	Give the business name instead. To call your contacts from your AI app, use the OsmO app, which syncs them
The sign-in page will not take your number	Sign-in accepts US, Canadian, UK, Australian and Indian mobile numbers	Use a mobile number from one of those countries
"Scheduling calls for later is available in the OsmO app"	Calls booked for a later time need the app	Ask for the call now, or schedule it in the OsmO app
A call is refused for the same number	OsmO places at most 5 calls to one number in any 24 hours	Try again once 24 hours have passed since the earliest of those calls

Turn it off

To disconnect, remove OsmO from your AI app's connector settings. Some apps do not tell OsmO when you do that. If you use the OsmO app, also open the Sharing card, then Connect AI apps, and tap Disconnect. If you only use OsmO from AI apps, email [email protected] with the mobile number you signed in with and we will end the access.

Questions people ask

Can Copilot call without asking me?

OsmO asks your AI app to read you who it will call and why, and to wait for your yes before it dials. Some apps also ask permission before using a connector at all.
