The process for connecting MCP clients to use your HXL widget differs depending on the client.
Connect Claude Desktop or ChatGPT as MCP clients by adding the custom MCP server URL and ECA consumer key that you previously noted. For details, see:
To render your widget in Slackbot, add and configure your custom Salesforce MCP server in Slack.
For complete details, see Connecting an MCP server to the Slackbot MCP Client. These options are relevant for Salesforce MCP servers:
https://api.salesforce.com/platform/mcp/v1/custom/HotelInfoMCPServer.HXL widgets don’t currently render when using Block Kit for Slackbot. Block Kit extends the MCP Apps protocol so MCP servers can return native Slack Block Kit JSON when Slackbot is the client.
Warning
After you connect your MCP client to your org, test that the widget renders the data correctly by running a prompt that invokes it. Each client is different, though most have a chatbot window or UI element where you can enter a prompt.
For example, to see the hotel info widget in action, try this prompt:
Tell me about the Four Seasons Resort in Maui.
For more robust testing, check out MCPJam which helps you test, debug, and evaluate MCP servers, MCP apps, and ChatGPT apps.
