MongoDB Model Context Protocol Server
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.
403 critical findings reported by cisco-skill-scanner, agent-audit-kit, 19 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
This artifact ships from 3 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/mongodb-js/mongodb-mcp-server, 710 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- mongodb-mcp-server
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 595 findings across every scanner that examined this package. 383 of 403 findings rated critical by their scanner were 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.
471 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file 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.

Rules: COMMAND_INJECTION_EVAL · Files: /repo/tests/eval/scripts/reportCi.ts · reported by cisco-skill-scanner
Critical command injection and DNS rebind vulnerabilities detected.
The artifact exhibits critical command injection vulnerabilities through `child_process`, `eval`, and `Function` constructor calls in files like `src/setup/aiTool.ts` and `src/ui/lib/tools/list-databases.ts`, allowing for shell execution. Multiple critical DNS rebind vulnerabilities are present in `src/index.ts` and other `src/transports` files, which could lead to network egress issues. Additionally, high-severity findings indicate potential credential access in `packages/mongodb-atlas-mcp-remote/src/config.ts` and `src/tokenManager.ts`, and dynamic code execution.
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.
