TCG Price API MCP server

Which MCP servers are TCG Price API'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 namedev.tcgdata/tcgdataverified in the MCP registry

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

On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 47 ms.

  • Whether its tools do the product's job has not been judged yet.

Once connected

  • Parameters are untyped or undescribed in 10 of 12 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.

  • not sure · Value a collection from dated price references
  • not sure · Suggest fair asking prices for marketplace listings

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 →

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.
