Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

compare_products Read-only

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.

slugsarray, required

Product slugs to compare.

Tools (6)

compare_products

read-only

Argument	Type	Description
slugs*	array	Product slugs to compare.

Input schema (JSON)

{
  "type": "object",
  "required": [
    "slugs"
  ],
  "properties": {
    "slugs": {
      "type": "array",
      "items": {
        "type": "string"
      },
      "maxItems": 5,
      "minItems": 2,
      "description": "Product slugs to compare."
    }
  }
}

get_product

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.

read-only

Argument	Type	Description
slug*	string	Product slug, e.g. "bambu-lab-x2d".
citation_limit	integer	How many citations to return, most notable first. The sentiment and speaker breakdowns always count every source regardless of this.
citation_offset	integer	Skip this many citations. Use it to page through the rest.

Input schema (JSON)

{
  "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."
    }
  }
}

get_tier_list

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.

read-only

Argument	Type	Description
tier	string	Optional. Return only this tier.
category*	string	Category slug, e.g. "3d-printers".

Input schema (JSON)

{
  "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\"."
    }
  }
}

list_categories

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.

read-only

Argument	Type	Description
limit	integer
query	string	Optional filter matched against the category name and description.

Input schema (JSON)

{
  "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."
    }
  }
}

search_products

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.

read-only

Argument	Type	Description
limit	integer
query*	string	Product or brand name, e.g. "Bambu Lab X2D".

Input schema (JSON)

{
  "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\"."
    }
  }
}

what_to_avoid

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.

read-only

Argument	Type	Description
category*	string	Category slug, e.g. "3d-printers".

Input schema (JSON)

{
  "type": "object",
  "required": [
    "category"
  ],
  "properties": {
    "category": {
      "type": "string",
      "description": "Category slug, e.g. \"3d-printers\"."
    }
  }
}
