Category Health and Science
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 3 of 5 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to SemanticDataCharter/sdcvalidator-ts). View diagnostics → Pass
- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 3 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability72
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 460 tokens (~115/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 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 4 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
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 3 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

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 →
check_schema_compliance ~55
Check whether an XSD schema follows SDC4 principles (restriction only, no xsd:extension). Does not validate instances.
| Name | Type | Req | Description |
|---|---|---|---|
| schema_path | string | yes | Path to the SDC4 data model XSD file. |
No output schema declared.
No examples provided.
recover_instance ~130
Recover an XML instance: each value with a semantic error keeps its value and is tagged with an ISO 21090 ExceptionalValue. Returns the recovered record and each value covered; a record with structural errors is rejected.
| Name | Type | Req | Description |
|---|---|---|---|
| instance_path | string | yes | Path to the XML instance (Governed Data Record) to validate. |
| reference_path | string | – | Optional path to a local copy of the SDC4 reference model (sdc4.xsd). Without it the model's include is fetched from its URL. |
| schema_path | string | yes | Path to the SDC4 data model XSD file. |
No output schema declared.
No examples provided.
validate_and_report ~122
Validate an XML instance and report every error: its path, its tier (structural or semantic), the constraint that failed, and the ExceptionalValue code recovery would use.
| Name | Type | Req | Description |
|---|---|---|---|
| instance_path | string | yes | Path to the XML instance (Governed Data Record) to validate. |
| reference_path | string | – | Optional path to a local copy of the SDC4 reference model (sdc4.xsd). Without it the model's include is fetched from its URL. |
| schema_path | string | yes | Path to the SDC4 data model XSD file. |
No output schema declared.
No examples provided.
validate_instance ~108
Validate an XML instance against its SDC4 XSD schema. Returns pass or fail with error counts.
| Name | Type | Req | Description |
|---|---|---|---|
| instance_path | string | yes | Path to the XML instance (Governed Data Record) to validate. |
| reference_path | string | – | Optional path to a local copy of the SDC4 reference model (sdc4.xsd). Without it the model's include is fetched from its URL. |
| schema_path | string | yes | Path to the SDC4 data model XSD file. |
