Three ways to use these prompts

Billy goes where you work

In the Finout console, from your IDE through the Finout MCP server, or shared with your team as a conversation link. Pick the channel that fits the moment.

01

In‑app, in your Finout console

Open Billy from any page in Finout. Your account context, MegaBill, virtual tags, allocations, and CostGuard scans are already loaded. Ask, refine, and turn the answer into a dashboard with one follow‑up.

02

From your IDE via the Finout MCP

Connect the Finout MCP server to Claude Code, Cursor, or Claude Desktop and use these same prompts from where you already write code. Cost answers without leaving your editor.

03

Shared with your team as a link

Any Billy conversation can be shared with a link. Hand a teammate the analysis, let them continue the thread, or drop the link into the Slack channel where the cost owner lives. Context travels.
