Test Your LLM App as a Claude Connector test-in-claude

Last update: July 29, 2026
IMPORTANT
Adobe LLM Apps is currently in Beta.
Features, workflows, and UI shown here do not necessarily represent the final state of the product. To join the Beta, send an email to llm-apps-beta@adobe.com.

After deployment, your LLM App exposes an MCP server URL. Add this URL to Claude as a custom connector, then test the generated actions and widgets.

This is the final verification step after building, customizing, or extending an app.

Plan requirements

Custom connectors using remote MCP are available on Claude, Claude Desktop, and Cowork for Free, Pro, Max, Team, and Enterprise plans. Free plan accounts are limited to one custom connector. For Team and Enterprise organizations, an Owner or Primary Owner must enable connectors before other members can use them.

Copy the MCP server URL

In LLM Apps:

  1. Open the App Detail page.
  2. Find Test the app.
  3. Under Staging environment, select Copy URL.

Add the custom connector

  1. Open claude.ai/new?modal=add-custom-connector. This opens the Add custom connector dialog directly.

  2. Enter:

    • Name — the connector name.
    • Remote MCP server URL — the MCP server URL you copied.

  3. Select Add.

    Claude — Add custom connector dialog

NOTE
Only use connectors from developers you trust. Anthropic does not control which tools developers make available and cannot verify that they will work as intended or that they won’t change.

Allow the generated tools

Each generated action is listed under Tool permissions on the connector page. By default, new tools are set to Needs approval, which prompts you to approve every call during testing.

Set each tool — or the whole Interactive tools group — to Always allow so testing is not interrupted by approval prompts.

Claude — set tool permissions to Always allow

Test the connector

  1. Start a new chat.

  2. Select + in the message box (or type /), hover Connectors, and turn on the connector you added for this conversation.

    Claude — enable the connector for the conversation

  3. Ask a question that matches one of the generated actions. For example: Show me some coffee.

Verify that:

  • Claude invokes the expected action.
  • The widget displays the expected sample data.
  • The text response matches the widget.
  • Widget controls work as expected.
