Virtual Model Context Protocol - Unified MCP server gateway
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.
2 critical findings reported by cisco-skill-scanner, agent-audit-kit, 1 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/JaimeCernuda/vmcp, 46 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- vmcp
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 19 findings across every scanner that examined this package. 1 of 2 findings rated critical by their scanner was among the dismissals.
Not reviewed is not the same as clean. Those 3 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 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.
Rules: COMMAND_INJECTION_EVAL, opt.nerlo-rules.nerlo-py-dynamic-exec, AAK-ANTHROPIC-SDK-001 and 2 more · Files: /repo/src/vmcp/testing/mock_server.py, src/vmcp/testing/mock_server.py, /repo/tests/integration/__init__.py and 1 more · reported by cisco-skill-scanner, nerlo-behavioral, agent-audit-kit
3 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/ci.yml · reported by agent-audit-kit
The model could have called any of these a false positive and did not.
3 AAK-ANTHROPIC-SDK-001
Files: src/vmcp/registry/registry.py, src/vmcp/gateway/server.py, src/vmcp/gateway/transports/stdio.py · reported by agent-audit-kit

1 AAK-OAUTH-3P-001
Files: pyproject.toml · reported by agent-audit-kit
3 The model called these false positives and our own check did not agree, so the dismissal was refused.
Rules: AAK-SEC-MD-001, SOCIAL_ENG_VAGUE_DESCRIPTION, MANIFEST_MISSING_LICENSE · Files: SECURITY.md, /repo/SKILL.md · reported by agent-audit-kit, cisco-skill-scanner
Critical risk of environment variable exfiltration
The artifact contains a critical finding related to environment variable exfiltration in `src/vmcp/registry/registry.py`. Additionally, multiple high-severity findings indicate potential for credential access and network egress across various files, including `src/vmcp/cli/main.py` and `src/vmcp/extensions/manager.py`. The artifact also uses SDKs with known vulnerabilities and has a DNS rebind vulnerability in `pyproject.toml`.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Showing 7 of 7; the rest are in the per-scanner reports above.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
