Trust breakdown (6 categories)

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 →

Supply Chain Security78

No malware found by supply-chain analysis.Pass
CVE check failed: a known high-severity CVE affects uuid 9.0.1, reached via @excalidraw/mermaid-to-excalidraw > mermaid > uuid. A fixed version is available. View diagnostics → Fail
No install/post-install scripts declared.Pass
Only part of the dependency tree could be resolved (250 of 471), so this covers what we could see, not the whole tree. View diagnostics → Partial

Provenance & Transparency45

Source repository is publicly reachable at the declared URL. View diagnostics → Pass
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 176 days ago).Pass
Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail

Schema Quality & AI Usability0

Schema quality not yet verified: our sandbox run of this package did not complete, so we have no schema to assess.Unverified

Stability & Change Management0

Stability not yet verified: our sandbox run of this package did not complete, so we have no schema to compare.Unverified

Tool Coverage0

Tool coverage not yet verified: our sandbox run of this package did not complete, so we have no tool definitions to assess.Unverified

Capabilities0

Protocol version not yet verified: our sandbox run of this package did not complete, so we never saw its MCP handshake.Unverified

Unverified: 4 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. How we score packages →

Dependencies 250 packages

250 packages in the resolved dependency tree · 207 deprecated · 85 stale · 3 without a linked repository.

The dependency tree was only partially resolved, so these counts may be incomplete.

MCP tools

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.

Tools for package channels are captured by running the package in an isolated sandbox. The most recent sandbox run could not capture a tool list from this package.
