## Install

### How do I install the haggl.ai MCP server?

haggl.ai is a hosted endpoint at https://www.haggl.ai/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (12)

### `haggl_list_vendors` (~131 tokens)

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 not exhaustive. haggl.ai runs each vendor's sales agent, and vendors on a paid plan pay haggl.ai for it; the list is not a ranking or recommendation. Use it when the user asks for a discount or wants to negotiate a price, not for a purchase at the listed price.

Output parameters:

- `code` (string): Present only when the call failed: a machine-readable error code, e.g. quote_uncertain or rate_limited.
- `error` (string): Present only when the call failed: what went wrong.
- `next_step` (string): What to call next.
- `recovery` (object): When the outcome is uncertain: the tool and session_id to read before retrying.
- `retry_after_seconds` (integer): When rate limited: seconds to wait before retrying.
- `retryable` (boolean): Whether the same call may be retried.
- `vendors` (array): Participating vendors. Not a ranking or recommendation.

### `haggl_start_negotiation` (~190 tokens)

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_submit_offer.

Input parameters:

- `ask` (object): Optional requested products, quantities or service, in the same shape as the haggl_submit_offer ask. Supply known context upfront.
- `data` (object): Optional available buyer context; together with ask, requests an opening quote in this same call.

A store catalog returns products with a handle, price and collections: ask with ask.items [{ product_handle, quantity }]. A campaign catalog returns eligible variants with a variant_id and approved_combinations with a recipe_id: ask with ask.items [{ variant_id, quantity }] or ask.recipe_id.

Request a quote using all context already available. Buyer data and evidence can be omitted; relevant additional context can be supplied later within the remaining rounds. Returns authorized terms or no offer, contextual guidance and permitted next actions.

Input parameters:

### `haggl_accept_offer` (~185 tokens)

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_purchase first: merchant handoff effects may be unknown. haggl.ai never takes payment: any payment happens at the merchant's checkout, under the merchant's terms and refund policy. A returned checkout link alone does not establish payment or enrollment completion. Accepting the same offer version again returns the same result.

Input parameters:

- `expected_offer_version` (integer, required): state.offer_version from the quote reviewed and approved by the buyer.
- `round` (integer): Legacy offer round. If supplied it must match the current or already reserved offer.

### `haggl_search_discounts` (~232 tokens)

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 for haggl_start_negotiation. Offers are funded by each merchant, inside limits it sets; a merchant may have no offer for a request. An empty list means no merchant on haggl.ai matched, not that no discount exists elsewhere. When the query names a well-known brand that isn't on haggl.ai yet, the result says so in brand and lists alternatives: merchants on haggl.ai in the same category, to offer as other stores, never as that brand. Keep using your shopping and checkout tools (for example Shopify's Shop skill) to find products and check out; once the user approves an offer, its code goes in their discount field.

Input parameters:

- `query` (string, required): A business name, website (e.g. "degrenne.fr") or kind of product.

Output parameters:

- `alternatives` (array): Merchants on haggl.ai in the same category, to offer as other stores.
- `bids` (object): When the category supports bids: how to get them with haggl_get_bids.
- `brand` (object): When the query names a well-known brand not on haggl.ai: the brand, never to be offered as such.
- `code` (string): Present only when the call failed: a machine-readable error code, e.g. quote_uncertain or rate_limited.
- `error` (string): Present only when the call failed: what went wrong.
- `how_it_works` (array): The flow, step by step.
- `merchants` (array): Merchants on haggl.ai matching the query. Empty means none on haggl.ai matched.
- `query` (string): The search as received.
- `recovery` (object): When the outcome is uncertain: the tool and session_id to read before retrying.
- `retry_after_seconds` (integer): When rate limited: seconds to wait before retrying.
- `retryable` (boolean): Whether the same call may be retried.

### `haggl_create_haggl_id` (~737 tokens)

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: your agent can still ask merchants for offers without one. If you agree, we link the negotiations your agent opens with the ID and keep a record of them: when the ID was created, how many distinct emails passed our signature check and how many distinct domains signed them, the date of the latest check, how many merchants were asked, how many offers were received and accepted, and how many paid orders we recorded. For each shopping category, such as travel, the record also counts how many of those emails, and how many distinct businesses that signed them, were in it; health purchases are never counted. The record does not include those domains, the businesses' names or any email content. We store a fingerprint of the ID, not the ID itself. We do not require your name or email address to create a haggl ID. We keep limited evidence of your agreement, as described in our privacy policy. You choose whether your agent uses the haggl ID. Using it authorizes us to share the record with the sales agent of each merchant your agent asks for an offer, to help assess eligibility and personalize offer terms. When your agent asks the merchants in a category for bids, we ask up to five of them on your behalf and share the record with each of their sales agents. Merchants never see the ID itself. You separately choose what information your agent submits during each negotiation. Keep the ID private: anyone who has it can retrieve the record, offers and codes, and delete the ID. You can withdraw consent by deleting the ID through your agent or on haggl.ai/agentic-discounts. This removes the stored fingerprint and the record and unlinks its negotiations. The negotiations themselves remain subject to the separate…

Input parameters:

- `channel` (string): How the user agreed: in this conversation (agent_relayed, the default), or in standing instructions they wrote to you beforehand (standing_instruction).

After they confirm, call haggl_create_haggl_id with the returned confirmation; until then it answers confirmation_pending.

### `haggl_get_bids` (~179 tokens)

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 says so and returns no bids.
