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 Security50
  • Malware scan not yet available for this package.Unverified
  • No known CVEs affecting this package version or its production dependencies.Pass
  • Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
  • No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency32
Schema Quality & AI Usability0
  • Schema quality not yet verified: this package installed, but its server did not start, so we have no schema to assess.Unverified
Stability & Change Management0
  • Stability not yet verified: this package installed, but its server did not start, so we have no schema to compare.Unverified
Tool Coverage0
  • Tool coverage not yet verified: this package installed, but its server did not start, so we have no tool definitions to assess.Unverified
Tool Safety0
  • Tool safety not yet verified: this package installed, but its server did not start, so we have no tool text to scan.Unverified
Capabilities0
  • Protocol version not yet verified: this package installed, but its server did not start, so we never saw its MCP handshake.Unverified

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. How we score packages →

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. 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 →

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.
