Loading the registry…
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.
15 critical findings reported by cisco-skill-scanner, agent-audit-kit, 13 of them in the installed artifact. 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/pulseengine/mcp, 149 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- mcp
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
6 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 149 findings across every scanner that examined this package. 1 of 15 findings rated critical by their scanner was among the dismissals.
Not reviewed is not the same as clean. Those 1 finding stand exactly as their scanners reported them, at full severity, as they would have without this review.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
28 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

2 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.

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.

1 The model gave no reason we were willing to publish, and a verdict without one is not usable evidence.
Rules: AAK-MCP-SSRF-001 · Files: mcp-external-validation/python_tests/test_basic_connection.py · reported by agent-audit-kit
Artifact has critical command injection, path traversal, and SSRF vulnerabilities.
The artifact contains critical command injection vulnerabilities in `mcp-external-validation/src/fuzzing.rs`, allowing for shell execution. A critical path traversal vulnerability in `mcp-external-validation/src/config.rs` could permit unauthorized file system access. Additionally, a critical Server-Side Request Forgery (SSRF) vulnerability in `integration-tests/src/end_to_end_scenarios.rs` could lead to network egress. Multiple taint-related findings in `pulseengine-auth` and `pulseengine-security` components also warrant attention.
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.
