"The bot says I can merge two shopping carts from different stores." "The AI doesn't know which store to order from." "The chatbot promises a single package when I have two orders." Three failures where a miscalibrated multi-store bot hallucinates merging or ignores store_id.
An e-commerce multi-store cart AI chatbot does not replace MSTRCART agents (#803). It reads MSTRCART-MAP, cites store_name stock_scope shipping_fee, and handoff return reorder to humans without promising impossible cart merging.
This guide #804 covers intents bot_mstrcart_*, flow MSTRCARTbot, and KPI mstrcart_bot. Pair bot of the MSTRCART playbook (#803). Multi-store AI use case: explain tier 1 shipping availability.
Summary
Why automate multi-store shopping carts with a bot?
"Which store", "why not in my cart", "two shipping fees" arrive at the PDP footer store picker widget. A calibrated bot identifies store_id, cites catalog_scope, and distinguishes delivery availability by store without promising virtual merge.
What the tier 1 multi-store bot resolves
Store picker: store_name store_url catalog_scope_copy map
No merge: no_merge_cart_copy NO-MERGE-CITE-BOT map
Stock scope: stock_scope_copy STOCK-API per store map
Shipping store: shipping_fee_by_store_copy map
Handoff CS: #803 payload store_id order_ref
Multi-store groups generate tickets if the bot confuses Markets (Shopify, 2026 stores). Without a grounded bot, AI routes international Markets or promises cart fusion.
MSTRCARTbot vs MSTRCART #803, Markets, CARTCALCbot #802 and anti-hallucination #123
Six contents, six distinct multi-store cart journeys.
Quick matrix
#804 MSTRCARTbot: tier 1 bot available delivery store picker no merge
#803 MSTRCART: agents return reorder wrong store escalate
International Markets: one shop country distinct separate stores
CARTCALCbot #802: total difference distinct calculation which store
Bot checkout #292: fee coupon one distinct multi-store shop
Anti-hallucination #123: store stock = API whitelist only
Pipeline: #804 bot available store tier 1 → #803 agents return reorder routing.
Which bot_mstrcart_* intents should be configured?
Eight multi-shop bot intents mapped to mstrcart_* typologies #803.
Eight bot_mstrcart intents
bot_mstrcart_store_picker: store_name store_url catalog_scope_copy map
bot_mstrcart_no_merge: no_merge_cart_copy NO-MERGE-CITE-BOT map
bot_mstrcart_availability: stock_scope_copy STOCK-API store map
bot_mstrcart_shipping: shipping_fee_by_store_copy map
bot_mstrcart_split_ship: split_ship_policy_copy SPLIT-SHIP-CITE-BOT map
bot_mstrcart_wrong_store: redirect store_url correct map
bot_mstrcart_return: return_store_routing handoff #803 map
bot_mstrcart_handoff: reorder cancel → MSTRCART803-HANDOFF-BOT
Tier 1 auto: store_picker no_merge availability shipping if MSTRCART-MAP active + guardrails STORE-ID NO-MERGE STOCK-API.
bot_mstrcart_handoff wrong store reorder → agents #803 payload store_id order.
How to consume MSTRCART-MAP #803?
The bot reads MSTRCART-MAP #803: store_id, store_name, store_url, catalog_scope_copy, no_merge_cart_copy, split_ship_policy_copy, shipping_fee_by_store_copy, stock_scope_copy, return_store_routing_copy, account_scope_copy, markets_reroute_copy.
Lookup grounded multi-store embed
STORE-ID-CITE-BOT: store_name store_url cite map verbatim
NO-MERGE-CITE-BOT: no_merge_cart_copy cite if merge requested map
STOCK-API-GROUNDED-BOT: inventory per store_id API only not shared invent
SPLIT-SHIP-CITE-BOT: split_ship_policy_copy cite if separate packages map
NO-MERGE-PROMISE-BOT: bot never promises cart merge map
STORE-DETECT-BOT: current URL shop domain → store_id map row
MARKETS-REROUTE-BOT: one country shop → international distinct multi-store
MSTRCART803-HANDOFF-BOT: reorder return → #803 agents MS-7 route
Alignment anti-hallucination (#123): stock shipping = MSTRCART-MAP + per-store API whitelist only. Bot does not invent merge.
MSTRCARTBOT-SUP policy in six rules
Six multi-store cart bot rules responsible.
MSTRCART-MAP-GROUNDED-BOT: store response from map only
STORE-ID-CITE-BOT: store_name store_url cites each map response
NO-MERGE-CITE-BOT: no_merge_cart_copy cites without map exception
STOCK-API-GROUNDED-BOT: store_id inventory availability API not LLM invent
NO-MERGE-PROMISE-BOT: merging cart stores prohibited bot map
STORE-DETECT-BOT: detect shop domain URL before responding stock ship
Flow MSTRCARTbot MSB-1 to MSB-8
Eight-step multi-store bot flow embed store picker PDP.
MSB-1 Classify: bot_mstrcart_* intent detect keyword store merge cart delivery availability
MSB-2 Store detect: shop domain URL product_url → store_id MSTRCART-MAP row
MSB-3 MSTRCART-MAP: catalog no_merge ship stock return account markets reroute
MSB-4 Stock ship lookup: inventory shipping profile per store_id API STOCK-API-GROUNDED-BOT
MSB-5 Guardrail: STORE-ID NO-MERGE STOCK-API SPLIT-SHIP MARKETS HANDOFF NO-MERGE-PROMISE
MSB-6 Respond: TPL-MSTRCARTbot grounded store picker availability ship max 3 sentences
MSB-7 Handoff or close: wrong store return reorder #803 payload or close store_url sent
MSB-8 Log: intent store_id tag mstrcart_bot store_cited no_merge_cited handoff Y/N
Example TPL-MSTRCARTbot-NOMERGE
“ [no_merge_cart_copy map.] Store [store_A name url] and [store_B name url]: separate orders. NO-MERGE-CITE-BOT STORE-ID-CITE-BOT. ”
TPL-MSTRCARTbot and touchpoint templates
Four short multi-store embed templates.

Multi-store touchpoints
Keyword which store: bot_mstrcart_store_picker instant
Keyword add cart other site: bot_mstrcart_no_merge trigger
PDP OOS current store: bot_mstrcart_availability alt store proactive

Edge cases and reroutes
Five tier-1 cases excluded standard multi-store bot.
One country Markets shop: MARKETS-REROUTE-BOT international distinct separate stores
Total cart discrepancy: CARTCALCbot #802 distinct store breakdown
Reorder wrong store cancel: MSTRCART803-HANDOFF-BOT agents #803 MS-7
Return which store: bot_mstrcart_return handoff return_store_routing #803
SSO account cross-store: account_scope_copy cite handoff #803 if complex
Delivery availability tier 1 STORE-ID NO-MERGE. Reorder return cancel → handoff #803.
Essential mstrcart_bot KPIs
Five MSTRCARTbot steering metrics.
mstrcart_bot_store_cite_rate: STORE-ID-CITE-BOT / total bot_mstrcart
mstrcart_bot_no_merge_cite_rate: NO-MERGE-CITE-BOT / bot_mstrcart no_merge
mstrcart_bot_merge_promise_violations: target audit bot promise merge 0
mstrcart_bot_correct_store_redirect: correct store_url sent / wrong_store intent
mstrcart_bot_handoff_rate: escalate #803 / total mstrcart bot
Target: mstrcart_bot_merge_promise_violations 0 and mstrcart_bot_store_cite_rate greater than 95%.
MSTRCARTbot anti-patterns
Five common multi-store cart bot mistakes.
Promising cart merger bot: NO-MERGE-PROMISE-BOT no_merge_cart_copy map
Invented shared stock: STOCK-API-GROUNDED-BOT per store_id API only
Not citing store: STORE-ID-CITE-BOT store_name store_url mandatory
Confusing Markets: MARKETS-REROUTE-BOT verify multi-store vs one shop
Return without handoff: bot_mstrcart_return MSTRCART803-HANDOFF agents #803
