Last9 MCP Server - Model Context Protocol server implementation for Last9

Version:: 0.12.0
License:: Apache-2.0
Author:: Last9
Provenance:: Found by crawling (provenance, not a security rating)

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.

4 critical findings reported by cisco-skill-scanner. The composite score alone does not reflect this — read the per-scanner reports below.

github_release: https://github.com/last9/last9-mcp-server, 0 findings

Install

Choose your runtime: the CLI writes the mcpServers config entry for that target.

nerlo install --target claude-code -- @last9/mcp-server

Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.

Your view:

10 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.

AI review of these findings

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.

Upheld as real: 72
Dismissed as false positives: 6
Not reviewed: 0

Out of 78 findings across every scanner that examined this package. None of the 4 findings rated critical by their scanner were dismissed.

Why those were dismissed

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.

3 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.
Rules: AAK-AGENT-002, FILE_MAGIC_MISMATCH, opt.nerlo-rules.nerlo-install-run-bundled-artifact · Files: AGENTS.md, /repo/CLAUDE.md, /repo/AGENTS.md · reported by agent-audit-kit, cisco-skill-scanner, nerlo-install-instruction
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/release.yaml · reported by agent-audit-kit

In installed code — never dismissed

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.

What the review concluded

Critical command injection and dynamic execution capabilities detected.

Critical command injection vulnerabilities are present in `/repo/bin/cli.js` and `/repo/bin/download-binary.js`, enabling shell execution. Dynamic code execution capabilities are also identified in `/repo/bin/download-binary.js`. A high-severity finding indicates potential credential access via `internal/telemetry/logs/attributes_for_pipeline.go`. Additionally, multiple medium-severity findings include file magic mismatches and known vulnerabilities in dependencies.

Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
