Short answer: Not that we could find. We found no calling feature in the DeepSeek chat app and no official way to add a connector to it. The DeepSeek API supports tool calling, but it is not an MCP client, so a developer would have to build the bridge. If you want an AI to call a business today, the practical route is an app that takes connectors, such as Claude, ChatGPT or Grok, with OsmO added.
The DeepSeek app has no phone calling and no custom connectors that we could find.
The DeepSeek API does function calling; you would write the code that turns a tool call into a phone call.
DeepSeek Harness, a separate agent in public preview, ships an official MCP client.
For calls without code, use OsmO in an app that takes connectors.

- Sign in with your mobile numberYou get 50 free credits. Nothing to pay.
- Add OsmO to your AI appChatGPT, Claude, Grok and other apps that take connectors.

The full guide
Three ways people try it
| Route | Calls a business? | Effort |
|---|---|---|
| DeepSeek chat app | No option found | None, but no documented way to add a phone |
| DeepSeek API with your own tool | Only if you build the calling part | High: code, hosting, sign-in |
| DeepSeek Harness (MCP client) | Possibly, with an MCP calling server; we have not tested OsmO with it | Medium: preview software |
| Claude, ChatGPT or Grok with OsmO | Yes | Low: add the connector, sign in |
Using DeepSeek Harness with OsmO
DeepSeek Harness is an open-source agent from DeepSeek, in public preview at the time of writing, with an official MCP client. We have not tested OsmO with it, and we could not confirm that it supports remote servers with OAuth sign-in. If it does, the address is https://api.getosmo.app/mcp; as preview software, check its documentation first.
The simpler route
If what you want is "an AI that phones the shop for me", the model behind it matters less than the app. Claude, ChatGPT, Grok and others accept OsmO in a couple of minutes, and you can still use DeepSeek for everything else.
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
