A Model Context Protocol server providing tools to analyze network traffic captures using Wireshark/TShark
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
2 critical findings reported by agent-audit-kit. The composite score alone does not reflect this — read the per-scanner reports below.
This artifact ships from 2 sources and their verdicts differ. The worst is github (Flagged). Installing from a cleaner source does not mean the others are safe — check the source you actually install from.
github: https://github.com/li-yanliang/mcp-wireshark, 47 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- mcp-wireshark
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
5 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 41 findings across every scanner that examined this package. None of the 2 findings rated critical by their scanner were dismissed.
These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Critical DNS rebinding and credential exposure risks identified.
The artifact contains critical DNS rebinding vulnerabilities in `src/mcp_wireshark/server.py` and `sse_bridge.py`, which could allow network egress control. High severity findings include potential credential exposure in `decode_payload.py` and an infinite loop in `src/mcp_wireshark/session_manager.py`. Additionally, the artifact uses an outdated SDK with a known CVE and includes an Anthropic SDK in `src/mcp_wireshark/server.py` and `sse_bridge.py`.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
