stierproducts
Registry code: 0d5edc80fdb09b6e
stierproducts publishes one S-to-F tier list per product category, consolidated from independent research runs over expert reviews and owner reports. Every placement is cited.
Call list_categories first if you do not know the exact category slug. get_tier_list answers a "what is the best X" question in one call. what_to_avoid answers the half that listicles skip: the research deliberately ranks products buyers cross-shop but should not buy.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
list_categories open 6h ago
List 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.
{ "type": "object", "properties": { "limit": { "type": "integer", "default": 50, "maximum": 208, "minimum": 1 }, "query": { "type": "string", "description": "Optional filter matched against the category name and description." } } }arguments 15 lineswhat_to_avoid unknown never probed
The 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.
{ "type": "object", "required": [ "category" ], "properties": { "category": { "type": "string", "description": "Category slug, e.g. \"3d-printers\"." } } }arguments 12 linessearch_products unknown never probed
Find 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.
{ "type": "object", "required": [ "query" ], "properties": { "limit": { "type": "integer", "default": 20, "maximum": 50, "minimum": 1 }, "query": { "type": "string", "description": "Product or brand name, e.g. \"Bambu Lab X2D\"." } } }arguments 18 linesget_tier_list unknown never probed
The 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.
{ "type": "object", "required": [ "category" ], "properties": { "tier": { "enum": [ "S", "A", "B", "C", "D", "F" ], "type": "string", "description": "Optional. Return only this tier." }, "category": { "type": "string", "description": "Category slug, e.g. \"3d-printers\"." } } }arguments 24 linesget_product unknown never probed
Everything 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.
{ "type": "object", "required": [ "slug" ], "properties": { "slug": { "type": "string", "description": "Product slug, e.g. \"bambu-lab-x2d\"." }, "citation_limit": { "type": "integer", "default": 10, "maximum": 200, "minimum": 1, "description": "How many citations to return, most notable first. The sentiment and speaker breakdowns always count every source regardless of this." }, "citation_offset": { "type": "integer", "default": 0, "minimum": 0, "description": "Skip this many citations. Use it to page through the rest." } } }arguments 25 linescompare_products unknown never probed
Compare 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.
{ "type": "object", "required": [ "slugs" ], "properties": { "slugs": { "type": "array", "items": { "type": "string" }, "maxItems": 5, "minItems": 2, "description": "Product slugs to compare." } } }arguments 17 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
