MCP Servers

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.

Adding a server

You can only use a remote MCP server in BoltAI as the mobile OS doesn't allow running a local server. Make sure your server is reachable from the Internet (via SSE). To use a server on your local machine, use a tunnel service such as ngrok or Cloudflare Tunnel.

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 a couple of things:

1. Convert it to a SSE server using supergateway

2. Expose the service to the Internet using ngrok

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.

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:

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

Serve it using ngrok:

$> ngrok http 8071

ngrok                                                                                                                                                                                                                                (Ctrl+C to quit)

Add to BoltAI:

Your 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 ✌️
