MCP Aggregator - Aggregate multiple Model Context Protocol servers into a single endpoint with unified tool discovery and execution
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.
38 critical findings reported by cisco-skill-scanner, agent-audit-kit, 16 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- mcp-agg
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 161 findings across every scanner that examined this package. None of the 38 findings rated critical by their scanner were dismissed.
Not reviewed is not the same as clean. Those 82 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
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.

Artifact contains critical command injection and sensitive data handling risks.
The artifact includes capabilities for shell execution via child processes in `script/kill.ts`, `script/release.ts`, and `script/test-orchestrator.ts`. It also has critical command injection vulnerabilities in `src/cli/mcp.ts` related to standard I/O and tainted data. Additionally, the artifact handles JWT tokens, which could lead to credential access, and has multiple instances of network egress and file system access.
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.
Showing 25 of 48; the rest are in the per-scanner reports above.
