Assist is a platform where teams can build, host, and deploy internal AI software and agents in one place — giving companies a safe, controlled environment to standardize workflows and improve operations.

What are sandcastles?

Sandcastles are purpose-built internal apps created by non-technical teams on the Assist platform. They allow employees to build custom tools and workflows without engineering resources.

How much does Assist cost?

Assist uses pay-as-you-go pricing: provider costs + 5%, $0.17 per 1k tool calls, with no seat fees. Enterprise custom pricing is also available.

Do we need engineers to use Assist?

No. Assist is designed for non-technical teams to build and deploy AI tools. Engineers can use it too, but it doesn't require engineering resources to get started.

Creating an MCP Server

This guide walks you through creating an MCP server that exposes your workspace tools to external AI clients.

Before you begin

You need at least one tool available in your workspace. If no tools exist, the New Server button is disabled.
You need to know which tools you want to expose. You can select tools from any tool pack in your workspace.

Steps

1. Open the MCP Servers settings

Navigate to Settings, then select MCP Servers. You see a list of any existing servers or an empty state prompting you to create your first one.

2. Start creating a new server

Click New Server in the top-right corner, or click Create Your First Server if you have no servers yet. The Create MCP Server dialog opens.

3. Enter a name

Type a name in the Name field. Choose something descriptive that identifies the purpose of this server (for example, "Sales Tools" or "Development Utilities"). This name is shown to clients during the authorization flow.

4. Add a description (optional)

Type a description in the Description field. This helps you and your team remember what the server is for.

5. Select tools

Under Select Tools, check the boxes next to each tool you want to include. Tools are grouped by tool pack. Click a pack name to expand or collapse it.

The counter next to "Select Tools" shows how many tools you have selected.

If you have many tools, scroll down to load more.

6. Create the server

Click Create Server. The button is disabled until you provide a name and select at least one tool.

7. Copy the server URL

After creation, a confirmation dialog shows your new Server URL. Click the copy button next to the URL to copy it to your clipboard.

Save this URL. You need it to configure your AI client.

8. Close the dialog

Click Done to close the confirmation dialog. Your new server appears in the MCP Servers list with its name, tool count, creation date, and server URL.

Walkthrough: creating an MCP server from start to finish

Connect your client

After copying the server URL, open your AI client and add it as a remote MCP server. Follow the setup guide for your client:

When the client connects for the first time, you are redirected to authorize the connection. See Authorizing an MCP client.
