Send Prompts

👨‍💼 Our users expect the "Summarize" button to instantly craft a short, insightful take on the entry they're viewing. To make that happen, the UI needs to send a natural-language prompt to the host via our MCP bridge, then show the result without a page reload. If we don't deliver, people lose trust and the feature feels broken.

Here's the pattern you'll use from components:

// Send a prompt message to the host
await sendMcpMessage('prompt', {
	prompt:
		'Please ask CafeLedger get_balance for account espresso-ops and summarize the budget health.',
})

What you need to build:

Add a new 'prompt' message type to app/utils/mcp.ts so the bridge can validate payloads.
Add a function overload for sendMcpMessage('prompt', payload, options) that mirrors the 'link' overload but accepts { prompt: string }.
In the summarize button component, call sendMcpMessage('prompt', { prompt }).

👨‍💼 Let's wire up the prompt path so pressing "Summarize" works.
