Loading the registry…
The publisher performed an authenticated act of publication — proving control of a namespace in the official MCP registry, or appearing in a first-party catalogue an operator curates. That establishes WHO published it. It is not a security finding, and attested artifacts carry Flagged verdicts too.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- paypal/agent-toolkit
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 148 findings across every scanner that examined this package.
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.
30 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.
Rules: AAK-LANGCHAIN-001, CVE-2026-45134, PYSEC-2026-2555 and 11 more · Files: typescript/examples/langchain/package.json, python/examples/langchain/requirements.txt, /repo/python/examples/langchain/requirements.txt and 14 more · reported by agent-audit-kit, trivy, osv-scanner and 1 more
1 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.
Rules: AAK-GHA-IMMUTABLE-001 · Files: .github/workflows/release.yml · reported by agent-audit-kit
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.

2 FILE_MAGIC_MISMATCH
High severity vulnerabilities and credential egress detected.
The artifact contains multiple high severity vulnerabilities in its Python dependencies, identified in `python/requirements.txt`. Behavioral analysis indicates that Python code in `/repo/python/paypal_agent_toolkit/shared/paypal_client.py` and JavaScript code in `/repo/typescript/src/shared/client.ts` can perform network egress with secrets. Additionally, `AAK-LANGCHAIN-001` and `AAK-LANGCHAIN-003` in `typescript/package.json` indicate potential issues related to LangChain usage.
Concern level assessed by the review: High. 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.
