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 Security75
- No malware found by supply-chain analysis.Pass
- CVE check failed: an unpatched critical CVE affects this package; the score is capped at 0. See how to fix → View diagnostics → Fail
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 23 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency84
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to imattau/polypack-mcp). View diagnostics → Pass
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 46 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: 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 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 →

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.
