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 Security100
- 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
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency19
- Repository check failed: the declared repository URL returned HTTP 404. See how to fix → View diagnostics → Fail
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 15 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability69
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 239 tokens (~47/item across 5 items; 5 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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 5 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
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
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.

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 →
witnessed_feed ~40
Signed market facts (MA333, sigma bands, ATR on closed 4h bars) with the evidence block needed to recompute every figure. Returns JSON.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
witnessed_listings ~28
Curated listings with their evidence. Currently verified Tasmanian business data and physical survey work.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
witnessed_market ~46
Every listing on the open market, each self-signed by its publisher, with its purchase endpoint, price and delivery contract. Verify a listing against listing.publisher; do not trust the catalogue.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
witnessed_receipt_verify ~85
Verify a delivery receipt: Ed25519 signature against the delivery did:key, plus the sha256 of the body you actually received. Call this before acting on purchased data.
| Name | Type | Req | Description |
|---|---|---|---|
| body | string | – | The delivered bytes, to check the hash |
| signed | object | yes | The {receipt, signature} object from the X-DELIVERY-RECEIPT header |
No output schema declared.
No examples provided.
witnessed_verify ~40
Independently verify the published feed: canonical bytes, Ed25519 signature against the publisher did:key, and freshness. Use this before trusting any number from it.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
