MCP server for React Native best practices guidance with expert-level code remediation
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.
8 critical findings reported by cisco-skill-scanner, 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/MrNitro360/React-Native-MCP, 63 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- @mrnitro360/react-native-mcp-guide
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 39 findings across every scanner that examined this package. None of the 8 findings rated critical by their scanner were dismissed.
Not reviewed is not the same as clean. Those 2 findings 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.
5 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.
Rules: SOCIAL_ENG_VAGUE_DESCRIPTION, MANIFEST_MISSING_LICENSE, MANIFEST_INVALID_NAME · Files: /repo/.github/SKILL.md, /repo/.github/ISSUE_TEMPLATE/SKILL.md · reported by cisco-skill-scanner
2 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.

The model could have called any of these a false positive and did not.

1 The model gave no reason we were willing to publish, and a verdict without one is not usable evidence.

Artifact contains critical vulnerabilities for remote execution and network access.
The artifact exhibits critical command injection capabilities in `src/tools/index.ts`, allowing for shell execution. Multiple critical Server-Side Request Forgery (SSRF) vulnerabilities are present in `src/resources/index.ts` and `src/tools/index.ts`, enabling network egress. Additional critical findings related to data flow and processing are also identified within `src/tools/index.ts` and `src/resources/index.ts`. High severity SSRF and data taint issues further contribute to potential network and data manipulation risks.
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.
