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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability87
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 664 tokens (~132/item across 5 items; 3 tools + 2 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.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

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 →
categorize_product ~181
Map a free-text product description to a marketplace category path. Walks the taxonomy of the target marketplace one level at a time and returns the full path: one match per level, from the broadest category down to the most specific one, each with the reason it was picked. Use it to assign a listing category to a product you only have prose for. The last match carries `truncated: true` when the per-request token budget stopped the descent before a leaf. Every successful call is billed: with no `X-API-Key` header and no x402 payment proof the tool answers with the payment requirements instead of a result.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | free-text product description, up to 2000 characters. |
| store_id | string | yes | target marketplace, one of the values from `list_stores`. |
| Name | Type | Req | Description |
|---|---|---|---|
| categories | array | yes | One match per taxonomy level, from broadest to most specific. The last item may carry truncated=true |
| judge_approved | – | – | Whether a separate LLM judge confirmed the final category path is consistent with the description; null when the token budget ran out before the judge could run |
| judge_reason | – | – | The judge's stated reason for its verdict on the final path; null when the judge did not run or the final path was never judged |
| name | string | yes | Product name |
No examples provided.
list_stores ~68
List the marketplaces whose taxonomies are loaded, as `store_id` values. These are the only accepted values for the `store_id` argument of `categorize_product`. Free of charge on purpose: without it an agent would have to pay for a failed call to discover them.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
payment_info ~63
Return the x402 payment requirements for one categorization call. Meant for an agent that holds no API key: gives network, asset, recipient address and amount as JSON, so the payment authorization can be signed before calling `categorize_product`. Free of charge.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
