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. 77 · Caution

The sandbox observed nothing beyond the static findings; the proposal cites those.

Title: mcpbait: Credential pass-through configuration (KillerSkills verdict caution 77)
## 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 77/100**. Summary: no network, touches nothing outside the project, writes no memory. - See the findings below. Full trace and findings: https://killerskills.ai/skills/pypi/mcpbait/0.4.2 ## Findings with a location - `src/mcpbait/modules/elicitation_phish.py:36` · Credential pass-through configuration — src/mcpbait/modules/elicitation_phish.py:36 · Credential pass-through configuration — agent relays sensitive credentials - `docs/LEADERBOARD.md:112` · Instructs the agent to modify its persistent memory or instruction files — docs/LEADERBOARD.md:112 · Instructs the agent to modify its persistent memory or instruction files · informational: not an instruction file - `src/mcpbait/modules/memory_poisoning.py:53` · Instructs the agent to modify its persistent memory or instruction files — src/mcpbait/modules/memory_poisoning.py:53 · Instructs the agent to modify its persistent memory or instruction files · informational: not an instruction file ## Proposed change The attached patch removes the 3 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.
