BuyLater Docs

BuyLater lets you save a product you want to buy later and get notified when it is back in stock, drops in price, or a new model is released — or simply save it for later with no alert. You can save from the website or through an AI assistant.

For AI assistants (MCP server)

BuyLater runs a Model Context Protocol (MCP) server so assistants like Claude and ChatGPT can save and list products on your behalf.

Endpoint: https://buylater.com/api/mcp
Transport: Streamable HTTP
Authentication: OAuth 2.1 via Clerk. Sign-in is passwordless (email magic link). Clients register automatically (Dynamic Client Registration) — there is no manual setup. The first time you connect, you will be asked to sign in and approve access.

Tools

save_intent

Save a product to buy later, with a condition to watch for. Your email is taken from your sign-in, so you do not provide it.

product_name (required)
product_url (optional)
intent_mode (required): researching, back_in_stock, on_sale, or new_release
geo (optional, defaults to AU)

list_intents

List your current saved items. No parameters — it uses your sign-in to find your items.

Connecting

Claude / ChatGPT: add https://buylater.com/api/mcp as a custom connector and sign in when prompted.
MCP Inspector: run npx @modelcontextprotocol/inspector, connect to the endpoint using Streamable HTTP, and complete the OAuth sign-in.

Notifications

When your condition is met, BuyLater emails you. Every email includes a link to view or cancel the saved item.
