Evidence

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

Zero-context hunks: apply with git apply --unidiff-zero fix.patch on the tagged source of 0.3.0. If the behavior is intended, declare it (host under permissions.network, a line in the README) instead of removing it; the next crawl scores declarations.

Issue / PR body

Title: mcpvuln: Reads credential paths from the home directory (KillerSkills verdict caution 69)

## 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 69/100**. Summary: no network, touches nothing outside the project, writes no memory.

- See the findings below.

Full trace and findings: https://killerskills.ai/skills/pypi/mcpvuln/0.3.0

## Findings with a location
- `tests/test_cve_2026_rules.py:290` · Reads credential paths from the home directory — tests/test_cve_2026_rules.py:290 · Reads credential paths from the home directory
- `mcpvuln/vuln_analyzer.py:241` · Hidden zero-width characters detected — mcpvuln/vuln_analyzer.py:241 · Hidden zero-width characters detected — may conceal content
- `tests/test_cve_2026_rules.py:290` · References a credential file in the home directory — tests/test_cve_2026_rules.py:290 · References a credential file in the home directory

## Proposed change
The attached patch removes the 2 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.
