How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 713 tokens (~178/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management43
- Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_card Card metrics & history ~208
Use this when the user wants detailed metrics for a specific card: PSA 10 reference price, population, market cap, price changes, daily history, and canonical URL. Requires an exact card ID from search_cards. Prices are daily published observations in USD, not live or executable quotes. Null values mean data is unavailable for that field — do not substitute zero.
| Name | Type | Req | Description |
|---|---|---|---|
| historyDays | integer | – | Days of price history to include, counting back from the most recent published point. Default 90; max 365. Omit for standard 90-day view. |
| id | string | yes | Exact CARDZ card ID returned by search_cards, e.g. cmc_fc229f7ae1b256b2119fa79b. Do not guess or construct IDs; always obtain from search_cards first. |
| lang | string | – | Language for display labels in the response. Does not filter by card language; use tcg to narrow by game. Printing language is always returned in the result. |
No output schema declared.
No examples provided.
get_market TCG market rankings ~183
Use this when the user asks about the top-ranked cards by market cap, wants to know which cards are most valuable by the CARDZ index, or requests a leaderboard for Pokémon or One Piece graded cards. Returns the published ranking with PSA 10 prices, populations, market caps, and the effective date of the data. Market cap = PSA 10 reference price × verified PSA 10 population. This index does not represent the full trading-card market.
| Name | Type | Req | Description |
|---|---|---|---|
| lang | string | – | Language for display labels in the response. Does not filter by card language; use tcg to narrow by game. Printing language is always returned in the result. |
| limit | integer | – | How many top-ranked cards to return. Default 10, max 20. |
| scope | string | – | 'pokemon', 'one-piece', or 'all' (combined index). Default: all. |
No output schema declared.
No examples provided.
search_cards Search TCG cards ~204
Use this when the user names a card, set, or collector number and wants to find matching printings or get card IDs for further lookup. Searches CARDZ public graded Pokémon or One Piece cards. Returns candidate printings with names, sets, languages, market ranks, PSA 10 prices, populations, market caps, and canonical card links. Multiple candidates may match; call get_card with the exact id for full metrics. An empty result means no published match.
| Name | Type | Req | Description |
|---|---|---|---|
| lang | string | – | Language for display labels in the response. Does not filter by card language; use tcg to narrow by game. Printing language is always returned in the result. |
| q | string | yes | Card name or collector number. Examples: 'Charizard', '199/165', 'OP05-119', 'Van Gogh Pikachu'. At least one meaningful keyword. |
| tcg | string | – | Optional: 'pokemon' or 'one-piece'. Omit to search both games. |
No output schema declared.
No examples provided.
How do I install the CARDZ MCP server?
CARDZ MCP is a hosted endpoint at https://mcp.cardz.game/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
