What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • haggl_list_vendors

    List vendors that accept AI-agent price negotiations through haggl.ai. A vendor appears once haggl.ai is installed on its own store or website (the listed website): the haggl.ai Shopify app on that store, or its snippet detected on that site. Vendors can opt out, so the list is n

  • haggl_start_negotiation

    Start a price negotiation with a vendor. Returns contextual guidance, current permitted actions and a new session with a session id. No customer-profile selection is required. Skip this tool if REST initialization already returned a session; pass that session.id directly to haggl

  • haggl_search_catalog

    Search a vendor's catalog so the offer can name exact products, then follow the how_to_ask field of the result. A store catalog returns products with a handle, price and collections: ask with ask.items [{ product_handle, quantity }]. A campaign catalog returns eligible variants w

  • haggl_get_negotiation

    Read the canonical state, current offer version, guidance and permitted actions of an existing negotiation. Use after human changes, reloads, transport switches or uncertain results; this does not open another session.

  • haggl_submit_offer

  • haggl_accept_offer

    Accept the vendor's offer and lock in the deal. Consequential: only call after the buyer has approved this exact offer, every time. Provide the offer version the buyer reviewed and approved; a changed offer needs a new approval. Read state.acceptance_effects and state.commits_pur

  • haggl_search_discounts

    Find merchants that run a sales agent on haggl.ai, by business name, website or kind of product. Only when the user asks for a discount, a coupon, a promo code or a lower price; a purchase at the listed price is not a request for one. Returns matching merchants with a vendor_id f

  • haggl_create_haggl_id

    Create a haggl ID for the user, so offers and codes from different merchants stay together and can be read back later. Show the user this text first, and call this only if they agree: "haggl.ai, operated by MOOJO.ID, INC. ("we"), offers your agent a haggl ID. You can decline: you

  • haggl_request_haggl_id_confirmation

    Get a link for the user to read the haggl ID consent text and confirm it on haggl.ai, when they are not in this conversation to agree to it. Send them confirm_url (valid 30 minutes). After they confirm, call haggl_create_haggl_id with the returned confirmation; until then it answ

  • haggl_get_my_offers

    Read what haggl.ai holds for the user's haggl ID: when it was created and the negotiations, offers and codes linked to it, newest first.

  • haggl_get_bids

    Have the merchants on haggl.ai in one shopping category (for example travel) bid for the user at once, from their haggl ID record, without new proof. Works once the record holds a verified purchase in that category (from an earlier offer with signed email proof); otherwise it say

  • haggl_delete_haggl_id

    Delete the user's haggl ID and unlink the offers linked to it. Only when the user asks. Codes already issued keep working at the merchant until they expire.

  • haggl_hotel_cashback

    The haggl.ai hotel cashback offer: whether it is open, the tiers and rates, the hotels with a cashback agent (independent and boutique hotels in San Francisco, each with the vendor_id of its haggl agent), and the steps. No haggl ID needed. Call it when the user is choosing a hote

  • haggl_hotel_cashback_add_trip

    Optional, before asking a hotel's agent for a rate: prove one past trip to San Francisco (last 12 months) with its signed flight booking, hotel booking or hotel post-stay email, one email per call, to raise the user's cashback tier (1+ trips: returning, 3+ trips: frequent). Only

  • haggl_hotel_cashback_claim

    After the user booked the hotel whose agent's offer they accepted, before its reference code expired: claim the cashback with the hotel's booking confirmation email, exactly as received. Show the user these conditions first, and call this only if they agree: "haggl.ai (MOOJO.ID,

  • haggl_hotel_cashback_stay

    After the user checked out: send the hotel's post-stay email (final receipt or folio, thank-you for staying, or review request), exactly as received. It shows the stay happened, and haggl.ai sends the cashback within 2 business days.

  • haggl_hotel_cashback_get

    Read a hotel cashback claim made with the user's haggl ID: its status and what comes next.

Common questions

Is haggl.ai safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 26 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?
