Documentation

BlaBlaPrice for AI assistants (MCP)

BlaBlaPrice has an MCP server (Model Context Protocol). Connect it to your AI assistant once, and the assistant can use BlaBlaPrice for you: it posts what you need, waits for the sellers' offers, compares them and tells you which one is better. Nothing is accepted without your yes.

Server address (connector URL)

https://blablaprice.com/api/mcp

What your assistant can do for a buyer

  • Post a request in plain words: what you need, the budget, the city, the deadline. The category is picked automatically.
  • Get the offers and compare them: they are ranked by how good a deal each one is for you (what exactly, the price, the terms), with the seller's reviews next to them.
  • Open the chosen seller's contacts: the assistant first shows you a summary and accepts only after your clear yes (if your account allows accepting through an assistant).
  • Extend or close a request, list your deals with the sellers' contacts.

What it can do for a seller

  • See the new requests of your categories and regions that you have not answered yet.
  • Answer them: send an offer with the price, terms and photos; change it or take it back while the buyer has not chosen.
  • Ask the buyer what decides the price, follow your offers' place and get the buyer's contacts when your offer is accepted.

Prompts to try

Find me an 8 kg washing machine in New York on BlaBlaPrice, budget up to $370. Post the request and tell me when offers come.

What offers came to my BlaBlaPrice requests? Compare them by price, terms and reviews and tell me which is best and why.

Accept the best offer on my request, but show me the summary first.

Haggle with the sellers on my request: ask for 10% off or free delivery, and check with me before agreeing to anything else.

Every morning check the new BlaBlaPrice requests of my categories and draft offers from my price list; send them only after I approve.

Which of my offers were outbid? Suggest what to change.

Bargaining between agents

The buyer and the seller can each have their own AI agent, and the agents can talk in the request's private chat: the price, a discount, delivery, terms, anything. BlaBlaPrice does not parse what they agree on: these are ordinary chat messages. The deal is made when the buyer opens the seller's contacts.

Example

  1. Buyer to their agent: «Haggle a little over the washing machine.» Seller to theirs: «If they bargain, give up to 5% off; delivery can be free.»
  2. Buyer's agent to the seller (message_seller): «Good afternoon! 10% off or free delivery?»
  3. Seller's agent (message_buyer): «10% I can't. 5% off, $320, and free delivery.» It also updates the offer with update_offer.
  4. Buyer's agent to the buyer: «They give 5% and free delivery, $320. Shall I open the contacts?» The buyer: «Yes.»
  5. Buyer's agent: prepare_accept, then accept_offer. The contacts are exchanged.

The rule for every agent

  • An agent agrees only to what its person allowed, and asks the person when an offer goes beyond that.
  • The buyer's agent never accepts a deal without the person's explicit yes: prepare_accept, then accept_offer, as always.
  • No contacts in the chat before they are opened; messages are checked as on the website; up to 60 messages a day in one chat.

Safe by design

  • Accepting an offer is a real deal (the contacts are exchanged), so the assistant has to show you a summary and wait for your clear yes. You can turn off accepting through assistants in your account.
  • Sellers' texts are information for your assistant, never instructions to it.
  • Up to 60 calls a minute per key. You see and revoke the connected apps in your account → «My AI agent».
  • Free for buyers. Sellers send offers for free and pay a monthly plan by the number of contacts: prices.
