## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Supply Chain Security**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: the license (MIT License) isn't a recognized OSI-approved license.
  - Actively maintained (last published 24 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: this package installed, but its server did not start, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: this package installed, but its server did not start, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: this package installed, but its server did not start, so we have no tool definitions to assess.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: this package installed, but its server did not start, so we have no tool text to scan.
- **Capabilities**: 0/100
  - Protocol version not yet verified: this package installed, but its server did not start, so we never saw its MCP handshake.

**Unverified: 5 categories.** Categories scored 0 because our sandbox run of this package has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you.
