Auditable receipts for AI shopping agents.
Brands pay to be considered. You get the fee. And a receipt anyone can check.

The rails are done. The trust is missing.
If a brand pays your agent, whose side is it on?
A brand's fee should buy a seat at the table, not the final answer. We use a flat toll over x402 to enter the shortlist. The fee is stripped from the data before scoring. Plain arithmetic ranks everything.
A receipt you can argue with.
Shortlisted is a tool your agent calls before it buys, built as an MCP server. Add it once to Claude or any MCP client, and every shopping decision comes back with cryptographic proof.
- One MCP server. Add it once to Claude or any MCP client.
- Every shopping decision returns a signed receipt.
- Re-runnable arithmetic. Verifiable by anyone.
Add it in one line.
In Claude Code, run:
claude mcp add --transport http shortlisted https://app.shortlisted.tech/mcp
Using Claude Desktop or claude.ai? Add a custom connector with this URL: https://app.shortlisted.tech/mcp
Ask your agent:
Find wireless earbuds under $100 with good battery life. Use Shortlisted and choose the weights yourself.
Your own Claude picks the criteria. Shortlisted ranks with plain arithmetic and signs the result.
Then ask: "Verify that receipt." Or paste it into the public verifier. Change any number and watch it fail.
Arithmetic, not AI.
A model turns your request into criteria, then gets out of the way. The ranking is plain arithmetic. Same inputs, same answer, every time.
The toll is stripped from the data before the scoring code sees it. There's a test proving two identical offers with different fees score the same.
See the test →Every receipt is signed. Anyone can check one holding only the receipt and our public key. If checking us required our permission, it wouldn't be an audit.
The toll belongs to you.
Advertising is a toll on attention. Agents remove the attention. The toll gets rebuilt on the shortlist, and it should be paid to you. Join the waitlist for early access.
