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 Security66
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (stop_watching_recalls). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1836 tokens (~229/item across 8 items; 8 tools + 0 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 Management3
- Stability observed for 1 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
- 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
- All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →
check_lab_report Check a lab report ~271
Check a children's product lab test report before the importer certifies. Upload the report PDF as file, or paste its text as text. Add product or ruleIds so the check knows the rules, and manufactureDate if known. Scores gaps: a rule the report does not cite, a failed result, a lab CPSC does not accept for that test, a test before the lab's acceptance, an old ASTM F963 edition, and missing or wrong dates. Returns a readiness score, each gap with how to fix it, and draft values for the CPSC eFiling certificate fields. It never says a filing is correct.
| Name | Type | Req | Description |
|---|---|---|---|
| file | object | – | The lab test report the user uploaded (a text PDF or a .txt file). |
| labId | string | – | The lab's CPSC lab ID, when the report does not show it |
| manufactureDate | string | – | When the goods were made, YYYY-MM-DD |
| product | string | – | What the product is and who it is for, such as "plush toy for ages 3+", so missing rules can be found |
| ruleIds | array | – | Rule ids from find_cert_rules, instead of product |
| text | string | – | The report text, when the user pasted it instead of uploading a file |

find_accepted_labs Find CPSC-accepted labs ~267
Shortlist testing labs that CPSC currently accepts for every test a product needs, in one country (default Vietnam and China). Pass ruleIds from find_cert_rules (testedRuleIds), and country if the user names one. For a toy, f963Sections narrows the ASTM F963 sections; metalParts adds the lead in metal test. Returns each lab's name, city, accreditation body and its CPSC detail page. Reads the live CPSC lab list. It does not book a lab or quote prices.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Country where the goods are made or tested, such as Vietnam or China (default: both) |
| f963Sections | array | – | Only these ASTM F963 sections for a toy, such as ["4.3.5.1(2)", "4.3.5.2", "4.6"] (default: all common toy sections) |

find_cert_rules Find the safety rules and certificate ~247
Find which US product-safety rules a consumer product must meet and which certificate the importer files: CPC (Children's Product Certificate, for products made for children 12 and under) or GCC (General Certificate of Conformity). Pass product as plain words, or describe what a photo shows. Add age and features (paint, small parts, batteries, magnets, metal parts) when known. Covers the 16 most common children's product types and 3 general ones. Returns each rule with its 16 CFR citation, whether a CPSC-accepted lab must test it, and the eFiling citation code. Use testedRuleIds with find_accepted_labs. It does not decide that a product is legal to sell.
