Claude Code: ask. ### `ingest_products` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Ingest (upsert) a batch of products into the BuyWhere catalog. Use this to add or update product listings from any merchant/source. Requires a valid API key with ingest permissions. Accepts up to 1000 products per call with source, SKU, title, price, URL, and optional metadata. ``` ## Only reads (12) Looks things up and changes nothing. Claude Code: allow. ### `compare_products` - The name "compare_products" says "compare": a word for reading.

Returns price, brand, rating, and category for each. ``` ### `compare_products_v2` - The name "compare_products_v2" says "compare": a word for reading. Description, as the server wrote it: ```untrusted-server-text REQUIRED deliver_to. Compare multiple products side-by-side. Always pass deliver_to="SG" (or your buyer's country).

Description, as the server wrote it: ```untrusted-server-text Use this whenever a user asks about prices, wants to find the cheapest option, or asks "what's the best price for X" or "where can I buy X for the lowest price". Returns schema.org/Product entities with schema.org/AggregateOffer (lowPrice, offerCount, priceCurrency) across all merchants. BUY-74597 degraded contract: when the candidates query cannot complete inside the user-facing timeout, this tool returns a 200-OK envelope with `meta.degraded=true`, `meta.status="degraded"`, `meta.emptiness_reason="api_error"` with `meta.degraded_kind="timeout"` (or `"partial_timeout"` / `"auth_failure"`), `meta.confidence="low"`, and `meta.diagnostic.timed_out_stage="catalog_search"`, with `best_price=null` and `alternatives=[]`. It never returns an unqualified empty result when the cause is timeout, auth failure, upstream exception, or circuit breaker. ``` ### `find_best_price_v2` - The name "find_best_price_v2" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text REQUIRED deliver_to.

BUY-74597 degraded contract: when the discount-index scan cannot complete inside the user-facing timeout, this tool returns a 200-OK envelope with `meta.status="degraded"`, `meta.emptiness_reason="api_error"` with `meta.degraded_kind="timeout"` (or `"partial_timeout"` / `"auth_failure"`), `meta.confidence="low"`, and `meta.diagnostic.timed_out_stage` (typically `offer_aggregation`).

Returns product records with title, description, image, price, and merchant information. Covers e-commerce platforms across Singapore, Malaysia, Indonesia, Thailand, Vietnam, and US. Use compact=true for agent-optimized responses with structured_specs, comparison_attributes, and normalized_price_usd fields.
