LifeReceipt — Your Purchases, Remembered

The Idea

We’ve all been there — you buy something expensive, keep the receipt somewhere “safe,” and then completely forget about it until you actually need it.

A warranty expires, a receipt is difficult to find, or you realize too late that you could have made a claim.

That made us think: what if our receipts could actually remember things for us?

That’s where LifeReceipt came from.

What We Built

LifeReceipt is a purchase vault that turns ordinary receipts into useful, intelligent assets.

Instead of simply storing receipts, it keeps track of purchases, warranty deadlines, receipt details, and potential claims. More importantly, we made these capabilities accessible to AI agents through WebMCP.

An agent can search for a purchase, check its warranty, find the receipt, and prepare a claim without the user having to manually navigate through everything.

For example, a user can ask:

“Find my Sony headphones, check if they’re still under warranty, retrieve the receipt, and prepare a claim if eligible.”

LifeReceipt can handle the investigation and preparation — but it stops before submitting the claim.

The user has to explicitly approve the action.

That human approval step was an important part of our design because we don't want an agent making consequential decisions completely on its own.

How We Built It

We built LifeReceipt as a React + Vite web application and created a WebMCP layer that exposes the application's capabilities as agent tools.

We implemented 9 tools covering purchase search, warranty checking, receipt retrieval, claim preparation, approval, submission, and claim status.

The UI was designed to make the whole process visible. Users can explore their purchases through the Purchase Vault, see upcoming warranty expirations through Warranty Radar, and follow the agent's actions through the Agent Activity Log.

What We Learned

The biggest thing we learned was that building for agents is different from building a normal website.

We had to think about what an agent should be allowed to do, what information it needs, and where a human should take over.

WebMCP made us think of the website as more than just pages and buttons. Each useful capability can become something an agent can discover and use.

Challenges

Getting the WebMCP integration and the normal website experience to work together reliably was one of our biggest challenges.

We also faced deployment issues with Netlify, including SPA routing and JavaScript MIME types. Fixing those issues taught us that a project isn't finished when it works locally — it also needs to work reliably in the real environment where people and agents will use it.

Why LifeReceipt?

We don't want LifeReceipt to be another place where receipts go to be forgotten.

We want it to be a place where your purchases stay useful long after you buy them — with an agent handling the boring work and a human staying in control of the important decisions.
