<h1 align="center">OsmO Phone Calls</h1>

<p align="center">
  <b>Let your AI make real phone calls for you.</b><br>
  Ask ChatGPT, Claude, Cursor, Codex, Gemini CLI, Grok or any MCP client to call a shop, clinic,
  restaurant or helpline. OsmO's voice AI makes the call and brings back
  the answer, a summary and the transcript.

```
You:   Call the pharmacy on Main Street and ask if they're open until 9 tonight.
AI:    I'll call Main Street Pharmacy (+1 555 0100) and ask whether they're open until 9 tonight. OK?
You:   Yes.
AI:    (OsmO places the call, then reports what the pharmacy said, with a summary and transcript.)
```

*This is an illustration of the flow, not a recorded conversation. The number is a placeholder.*

**New users get 50 free credits** at [getosmo.app/login](https://getosmo.app/login), in the US, Canada,
the UK and Australia. An answered call uses 3 credits, however long it is. A call nobody answers is
free. With free credits, OsmO calls businesses and toll-free numbers; calling your contacts and scheduling calls need an OsmO app plan.

There is nothing to install or run on your machine. Your AI app connects to OsmO's hosted MCP server.
You sign in once in the browser with your phone number and a one-time code. There is no API key.

## Connect your AI

Every app uses the same server URL: **`https://api.getosmo.app/mcp`** (Streamable HTTP, OAuth).
When you first connect, the app opens OsmO's sign-in page. Enter your phone number and the
one-time code **there**, never in the chat.

The "Guide" column links to OsmO's own step-by-step page for that app.

We have not tested the rows with no guide (OpenClaw, Hermes, Cline, Windsurf, OpenCode) end to end
ourselves. Those rows follow each client's own documented syntax. If a command is out of date for
your version, please [open an issue](https://github.com/Mountainheads-Private-limited/osmo-ai-plugins/issues).

### Claude Code plugin

The plugin adds the MCP server **and** the `osmo-phone-calls` skill, which tells the AI to confirm
before every call. Inside Claude Code:

```
/plugin marketplace add Mountainheads-Private-limited/osmo-ai-plugins
/plugin install osmo@osmo
```

On recent Claude Code versions this works in one step:
`/plugin install osmo --marketplace Mountainheads-Private-limited/osmo-ai-plugins`.
Then type `/mcp`, pick `osmo` and sign in. Install either the plugin or the `claude mcp add` server,
not both, so Claude doesn't see two copies of the tools.

### Codex plugin

The plugin carries the MCP server and the skill. In your shell:

```sh
codex plugin marketplace add Mountainheads-Private-limited/osmo-ai-plugins
codex plugin add osmo@osmo
codex mcp login osmo
```

### VS Code

`.vscode/mcp.json` (workspace) or your user `mcp.json`:

```json
{
  "servers": {
    "osmo": {
      "type": "http",
      "url": "https://api.getosmo.app/mcp"
    }
  }
}
```

### Cursor

`~/.cursor/mcp.json` or `.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "osmo": {
      "url": "https://api.getosmo.app/mcp"
    }
  }
}
```

### OpenClaw

```sh
openclaw skills install @getosmo/osmo-phone-calls
openclaw mcp set osmo '{"url":"https://api.getosmo.app/mcp","transport":"streamable-http","auth":"oauth"}'
openclaw mcp login osmo
```

### Hermes

`~/.hermes/config.yaml`, then `hermes mcp login osmo`:

```yaml
mcp_servers:
  osmo:
    url: "https://api.getosmo.app/mcp"
    auth: oauth
```

### OpenCode

`opencode.json` (follows OpenCode's documented remote-server syntax; not yet tested by us):

```json
{
  "mcp": {
    "osmo": {
      "type": "remote",
      "url": "https://api.getosmo.app/mcp"
    }
  }
}
```

## Example prompts

- "Call the pharmacy on Main Street and ask if they're open until 9."
- "Call my dentist and move my appointment to next Tuesday afternoon."
- "Find the customer-care number for my airline and ask about my refund."
- "Get me a table for 4 at Luigi's on Friday at 8 pm."
- "Ask the hardware store on Elm Street if they have a 10 mm socket set in stock."

## What it can and can't do

> With free credits, OsmO calls businesses and toll-free numbers; calling your contacts and scheduling calls need an OsmO app plan.

**With any account, including free credits:**

- Book, reschedule or cancel an appointment or a table.
- Ask a shop, clinic or restaurant about opening hours, prices, stock or an order.
- Get through a company's phone menu to customer service.
- Call listed businesses (shops, clinics, restaurants, helplines) and toll-free numbers, up to 5 in
  one go.
- Find a business near you, or a company's customer-care number, in your own country.
- Report the outcome, a summary and the transcript of every call it made.

**With an OsmO app plan** ([iOS](https://apps.apple.com/us/app/osmo-ai-phone-assistant/id6761623744),
[Android](https://play.google.com/store/apps/details?id=com.osmo.aicallassistant)):

- Call your saved contacts and people who called you in the last 30 days, for example to pass a
  message.
- Schedule a call for later, and list or cancel scheduled calls.
- Tell you who called your OsmO number and what they wanted, and change your call-screening rules
  and settings.

**It can't or won't:**

- Call emergency services. Dial your local emergency number yourself.
- Send text messages or email.
- Call personal numbers found on the web.
- Need card numbers, bank PINs, passwords or sign-in codes typed into the chat. None of its tools
  take them, the skill tells your AI never to ask for them, and the sign-in code goes on OsmO's own page.
- Dial anything before you say yes.

Calls come from the OsmO number for your country. The voice AI speaks English, Spanish and Hindi.

## Cost

| | |
|---|---|
| New users (US, Canada, UK, Australia) | 50 free credits when you sign in at [getosmo.app/login](https://getosmo.app/login). No card. Calls businesses and toll-free numbers. |
| An answered call | 3 credits, however long it is |
| A call nobody answers | free |
| Contacts, scheduled calls, screening | need an OsmO app plan. Signing in to the app ends any free credits you have left. |
| After the free credits | keep calling with a plan in the OsmO app ([iOS](https://apps.apple.com/us/app/osmo-ai-phone-assistant/id6761623744), [Android](https://play.google.com/store/apps/details?id=com.osmo.aicallassistant)) |

If your free credits run out, the tools say so and point you to the OsmO app
([getosmo.app/app](https://getosmo.app/app)).

## Safety and privacy

- **You confirm every call.** `place_call` first returns a preview: who will be called, the number,
  what will be said and when. Nothing is dialled until your AI sends it back with your approval.
  Changing or deleting a setting or rule works the same way.
- **Sign-in happens on OsmO's page,** not in the chat. Never paste the one-time code into a chat. No
  API key or password is stored in this repo or in your AI app's config.
- **One host.** Everything goes to `https://api.getosmo.app` over HTTPS. This repo has no scripts,
  hooks or executable code.
- **Annotations.** Every tool declares MCP annotations (`readOnlyHint`, `destructiveHint`,
  `openWorldHint`). Tools that place calls are marked destructive and open-world, so well-behaved
  clients ask before running them.
- **Disconnect** by removing OsmO from your AI app's connector settings. If you use the OsmO app,
  also open the Sharing card → Connect AI apps → Disconnect. If you only use OsmO from AI apps,
  email team@getosmo.app with the mobile number you signed in with and we will end the access.

## Tools

The server's `tools/list` is the source of truth. This is what a standard MCP client (Claude,
Cursor, Codex, Gemini CLI, Grok and others) gets today: 27 tools. ChatGPT is served the release its
directory review approved, so its tool text can differ slightly.
