Configure Your Widget
Once you have your credentials, use the visual configurator to customize every aspect of the MCP Studio widget. Changes are reflected instantly in the embed snippet preview.
Configuration Sections
Domain
By default, MCP server endpoints are served from appatools.com. You can optionally set a custom domain to serve endpoints from your own domain.
Tools
Choose which of the 10 available tools your users can access. All tools are enabled by default — disable specific ones to focus the experience on what matters for your use case. A minimum of 3 tools is required.
Sources
Control which source types are available: websites, GitHub repos, documentation sites, API endpoints, or MCP servers. At least 1 source type must be enabled.
Colors
Match your brand with 10 customizable color options covering background, text, buttons, cards, steppers, and accents. Use hex color values.
Layout
Choose between horizontal (steps across the top) or vertical (steps along the left side) wizard layout.
Font
Select from 15 Google Fonts to match your application's typography.
Saving Configuration
Click Save Configuration in the configurator to persist your settings. The embed snippet updates automatically to reflect your choices — only non-default values are included to keep the snippet clean.
You can also manage configurations programmatically via the API.
