Chapter 14. Test with model context protocol (MCP) servers

Authorize and interact with connected MCP servers to use their integrated tools directly from the playground chat.

Prerequisites

You have deployed a model with tool-calling capabilities enabled in your project.
You have configured a playground instance for your project.
A cluster administrator has configured an MCP server, and the server is listed and available in the MCP tab of the settings panel.

Procedure

In the settings panel, click the MCP tab.
Select the checkbox for the server that you want to use.
Click the Auth icon next to the server name.
The Authorize MCP server dialog opens.
If the server requires a token, enter the token in the Access token field and click Authorize.
A Connection successful message appears.
Note
Authorization tokens for MCP servers are stored only for the current browser session. If you close your browser, you must re-authorize the server.
Click Close.
Click the View tools (wrench) icon for the same MCP server.
A modal appears, listing all available tools for that server. You can copy a tool name to use in the chat.
In the chat input field, type a query that uses one of the available tools.
Click the Send button or press Enter.
Note
After you send a prompt, the Send button changes to a Stop button. Click it to interrupt the model response.
