# MCP Servers (mobile)

An MCP server, short for Model Context Protocol server, is a lightweight program that exposes specific capabilities to AI models via a standardized protocol, enabling AI to interact with external data sources and tools.

MCP servers allows you to extend BoltAI's capabilities with custom tools and commands.

{% hint style="warning" %}
This guide is for the mobile app. To set up MCP servers for the Mac app, [follow this guide](/docs/plugins/mcp-servers.md).
{% endhint %}

## Adding a server

You can only use a remote MCP server in BoltAI for iOS as the mobile OS doesn't allow running a local server. Note that you can add an stdio server when using the Mac app. Make sure your server is reachable from the your phone (via SSE). To use a server on your Mac, make sure your phone and your Mac are connected to the same network. For convenience, set your Mac to use a static IP instead of DHCP.

Adding a server is simple. Go to Settings > MCP Servers, tap Add. Enter the server name, and your remote MCP server URL. Tap "Add Server".

### How to setup Zapier MCP server?

Zapier is an integration platform that hosts 7,000+ third-party apps and has 30,000+ actions. AI Actions equips your own AI or systems with the ability to run any action on Zapier (eg. Send a Slack message, find a Google Calendar event, draft a Gmail reply, create a HubSpot lead, etc.)

Using Zapier MCP server, you can build your own AI assistant to perform real-world tasks.

### How to use a local MCP server?

To run a local MCP server (stdio transport), you will need to convert it to a SSE server using [supergateway](https://github.com/supercorp-ai/supergateway). If you need to access it from the Internet, either host the MCP server using Cloudflare or use a tunnel service like ngrok or Cloudflare Tunnel.

{% hint style="warning" %}
**IMPORTANT**: Without authentication, anyone with the URL can interact with your MCP server. Make sure to keep it secret and turn the server off when not in use.
{% endhint %}

For example, here is a step-by-step guide on how I set up the Memory MCP server and expose it to the internet via ngrok.

**Start the SSE server using supergateway:**

```bash
npx -y supergateway \
    --stdio "npx -y @modelcontextprotocol/server-memory" \
    --port 8071 \
    --ssePath /sse \
    --messagePath /message
```

**Serve it using ngrok (optional):**

```bash
$> ngrok http 8071

ngrok                                                                                                                                                                                                                                (Ctrl+C to quit)

```

**Add to BoltAI:**

If you don't use ngrok, your server would look like this: `http://<your_mac_ip_address>:8071/sse`

If you use ngrok, your remote MCP server URL would be `https://xxxx-xxxx-xxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx.ngrok-free.app/sse`

Now you can use this MCP server on the mobile app ✌️
