A fix the maintainer can act on, with the evidence attached. It opens under your GitHub account in your browser; KillerSkills holds no token and never modifies the package. The fix is verified the only way we verify anything: the next crawl re-runs the new version in the honeypot. 76 · Caution
Evidence
The sandbox observed nothing beyond the static findings; the proposal cites those.

Title: mcpv: Hidden zero-width characters detected (KillerSkills verdict caution 76)
## What the honeypot observed KillerSkills ran **[email protected]** in an isolated sandbox (decoy credentials, recording proxy, syscall trace; engine 1.8.1) and scored it **CAUTION 76/100**. Summary: no network, touches nothing outside the project, writes no memory. - See the findings below. Full trace and findings: https://killerskills.ai/skills/pypi/mcpv/0.3.5 ## Findings with a location - `src/mcpv/vault.py:1` · Hidden zero-width characters detected — src/mcpv/vault.py:1 · Hidden zero-width characters detected — may conceal content - `src/mcpv/__init__.py:1` · Hidden zero-width characters detected — src/mcpv/__init__.py:1 · Hidden zero-width characters detected — may conceal content - `src/mcpv/server.py:1` · Hidden zero-width characters detected — src/mcpv/server.py:1 · Hidden zero-width characters detected — may conceal content - `src/mcpv/main.py:1` · Hidden zero-width characters detected — src/mcpv/main.py:1 · Hidden zero-width characters detected — may conceal content - `src/mcpv/valve.py:1` · Hidden zero-width characters detected — src/mcpv/valve.py:1 · Hidden zero-width characters detected — may conceal content ## Proposed change The attached patch removes the 4 lines above. If the behavior is intended, the fix is to declare it instead: list the host under `permissions.network` (or the MCP manifest) and say in the README why the package needs it; the next crawl will re-score it with the declaration taken into account. ## How this will be verified Nothing is "verified safe" by assertion. When a new version is published, KillerSkills re-runs it in the honeypot and the verdict page updates; you can trigger it early from the verdict page ("Re-scan after I publish a fix"). Reply here or at [email protected] if you believe the verdict is wrong; disputes are reviewed by a person and the outcome is published on the verdict page. _Proposed through killerskills.ai/threats by a user of the package, under their own GitHub account. The evidence is public; the package was never modified by KillerSkills._
We count proposals opened, not merged: a merge shows up as a new version that the crawl re-runs. Disputes: the maintainer can contest the verdict from its page; a person reviews it and the outcome is published.
