A side-by-side look at the Posokanei MCP and Stierproducts tier lists MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Posokanei MCP for e-commerce work as a local process; choose Stierproducts tier lists for e-commerce over a hosted endpoint. You can also run both side by side in one mcpServers block.
search_products, get_product, lookup_barcode.list_categories, search_products, get_tier_list.Rows where the two servers differ are marked.

search_productsSearch products by text.get_productGet details and retailer prices for a product id.lookup_barcodeFind product prices by EAN/GTIN barcode.list_products_by_categoryList category products, sorted by unit price by default.list_categoriesReturn a simplified category tree.list_retailersList known retailers.get_price_historyFetch product detail with history when available.compare_competitorsFetch comparable/competitor product data when available.compare_basketCompare a small basket across retailers.get_statsReturn high-level dataset stats.list_categoriesList the product categories that have a published tier list, newest research first. Call this first when you do not already know the exact category slug: slugs cannot be guessed reliably and every other tool takes one.search_productsFind ranked products by name or brand across every board. Returns the slug, category and tier for each match, which is what get_product and get_tier_list need next.get_tier_listThe full S-to-F tier list for one category: every ranked product with its tier, rank, LP, verdict, pros, cons, citation counts, GTIN barcodes and, where the maker published one, the announcement date. This is the primary tool and one call answers a "what is the best X" question completely. Call get_product for the quotes behind a placement.get_productEverything held on one product: its placement, verdict, pros and cons, GTIN barcodes, the announcement date where the maker published one, and a breakdown of how the cited sources read (how many were glowing, positive, neutral or negative, and whether they were outlets, named authors, video channels or forum owners). Then every citation in full, with a verbatim quote, who said it, and whether the link was fetched and confirmed. Use this when a claim needs backing up.compare_productsCompare two to five products side by side. They must share a category: LP is points on one category ladder and comparing across boards is meaningless, so a mixed request is refused rather than answered misleadingly.what_to_avoidThe products the research placed in the bottom tiers, and the ones it deliberately entered as traps buyers cross-shop but should not buy. Use it to answer "what should I not buy" and to check whether a product a user is considering was flagged.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
