Wherbi MCP server

Which MCP servers are Wherbi's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.wherbi/shoppingverified in the MCP registry

The registry name sits under wherbi.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-11-03 the server answered initialize and tools/list without a sign-in. First answer in 214 ms.

Should an agent connect itNot proven either way yet
  • Its tools do compare in-stock prices for one product across many shops, but not confirm delivery dates for a product at each shop.
  • Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

  • not sure · check totals including VAT and shipping before buying
  • cannot · confirm delivery dates for a product at each shop

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • list_sites

    The independent price-comparison sites this server searches (furniture and lighting, tools, toys, LEGO, board games, games, baby, pets, perfume, books, smart home and more): key, name, what each covers, its markets and languages, its home…

  • search_products

    Search every site's catalogue at once for a product, brand or kind of product (typos are corrected per site). Returns products with their site, page URL, manufacturer list price and a summary of current shop offers in the locale's market…

  • find_by_code

    Exact identity lookup on every site: a GTIN/EAN barcode, a manufacturer item number or a LEGO set number. Returns each site's matching product with its current shop offers in the locale's market (cheapest total first, each with its link)…

  • compare_prices

    Shop prices of one product version side by side in the locale's market on the site that lists it (cheapest total first, out of stock last; price, shipping, stock, when checked and the shop link), plus the same version's best price in that…

  • best_deals

    The largest real price drops right now in the locale's market across the sites: a shop's price against its own lowest price of the 30 days before (never a shop's own "was" price), with the site, product page and shop link.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "shopping": {
      "type": "http",
      "url": "https://wherbi.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http wherbi https://wherbi.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://wherbi.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
