Whose server it is
  • Registry nametw.botbuy/marketplaceverified in the MCP registry

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

On 2026-11-02 the server answered initialize and tools/list without a sign-in. First answer in 66 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: Browse used hi-fi and studio audio listings; Find second-hand computer memory and guitar amplifiers.
  • Checked on 2 of the 7 days it takes to judge reliability.

Once connected

  • For "Browse used hi-fi and studio audio listings", the likely first call is search_listings.
  • For "Find second-hand computer memory and guitar amplifiers", the likely first call is search_listings.
  • create_request, cancel_request, send_deal_message, create_listing, update_listing change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 15 of 18 tools: check arguments before calling.

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.

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_request, cancel_request, send_deal_message, create_listing, update_listing

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 →

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.
