Short answer: Not the Copilot most people use. We found no outbound calling in the consumer Copilot app, and it offers only Microsoft's own list of connectors. In Teams, Copilot can answer incoming calls for you in a preview, but it does not ring businesses. Builders have more room: Copilot Studio agents and GitHub Copilot in VS Code both take remote MCP servers, so either can add OsmO and place calls.
Consumer Copilot: no documented outbound calling or custom connectors.
Teams call delegation answers incoming Teams Phone calls (preview); it does not call out.
Copilot Studio: Tools → Add a tool → New tool → Model Context Protocol, with OAuth.
VS Code: run MCP: Add Server, or add OsmO to .vscode/mcp.json.
How it works

- Ask it to callOsmO calls, talks, and tells you what was said.
The full guide
Which Copilot are you using?
| Copilot | Places calls? | Can add OsmO? |
|---|---|---|
| Copilot app and copilot.com | Not documented | Not documented; Microsoft lists a fixed set of connectors |
| Copilot in Teams | Answers incoming calls (preview) | Only connectors an admin builds |
| Copilot Studio agents | Not documented | Yes, as an MCP tool |
| GitHub Copilot in VS Code | Not documented | Yes, as an MCP server |
Add OsmO to a Copilot Studio agent
- Open your agent, then Tools → Add a tool → New tool → Model Context Protocol.
- Enter
https://api.getosmo.app/mcpas the server URL (Streamable HTTP). - Choose OAuth 2.0 with dynamic discovery; OsmO supports dynamic client registration.
- Publish, then sign in to OsmO with your mobile number the first time the agent calls.
Add OsmO to GitHub Copilot in VS Code
Run MCP: Add Server from the command palette and choose HTTP, or add "osmo": {"type": "http", "url": "https://api.getosmo.app/mcp"} under servers in .vscode/mcp.json. VS Code handles the sign-in. Note that GitHub's cloud coding agent does not support remote servers that need OAuth, so use it from the editor.
What it costs
OsmO For my AI starts with 50 free credits when you sign in with your mobile number, with no card. An answered call uses 3 credits however long it lasts, and a call nobody answers is free, so the free credits cover about 16 answered calls. When they run out you can keep calling from the OsmO app.
Questions people ask
