Track pantry stock from receipts and buy groceries

A custom AI system reads receipts, estimates kitchen stock, checks grocery store availability and prices, buys groceries, and suggests recipes.

Done with a custom-built or unnamed agent

What they did
User ingests receipts and spending data into a custom service, then exposes a grocery budget envelope plus recipe history and financial data to a stock estimator tool. A second tool connects to local grocery store APIs for nutrition, availability, and prices. Both tools are exposed over a terse MCP surface to an AI harness (ChatGPT plus opencodev2) that produces stock updates, budgeting, and recipe recommendations.
How it went
The system genuinely saves the user time and money through ongoing stock estimates and recommendations. No purchase execution or quantitative results are stated.
Worth knowing
User offered to open-source the stack if others want it.

Try it yourself with Claude Code

In the folder [path to receipts] I have grocery receipts. Read them, build a running estimate of what's in my kitchen, and save it as [pantry file name]. Then list what I'm likely low on, suggest [number] recipes using what I have, and prepare a shopping list. You are done when the pantry file and shopping list exist; don't buy anything without showing me the list first.
