# pantheon-cli@0.2.103 npm security report

## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.2.103
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

LPM treats this as warn-only first-party agent extension lifecycle risk. After a user connects the CLI, it installs a Pantheon MCP server and agent instructions across several AI coding clients. This is a broad first-party agent-extension setup rather than an npm install-time attack.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** After a user connects the CLI, it installs a Pantheon MCP server and agent instructions across several AI coding clients. This is a broad first-party agent-extension setup rather than an npm install-time attack.

- **Trigger:** Running pantheon connect successfully, or running pantheon mcp-install after connecting.

- **Impact:** Pantheon gains a persistent callable integration and instructions in supported agent clients.

- **Evidence paths:** dist/pantheon.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-01T17:07:10.989Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Automatic multi-client MCP configuration and agent-skill installation.

- **Rationale:** The package performs broad persistent AI-agent configuration during explicit setup, which warrants a warning under the extension lifecycle policy. Static inspection found no install-time trigger, self-dependency chain, remote-code execution, or confirmed credential exfiltration.

- **Files touched:** ~/.cursor/mcp.json, ~/.claude.json, ~/.codex/config.toml, ~/.agents/skills/pantheon/SKILL.md, ~/.codex/skills/pantheon/SKILL.md

- **Network endpoints:** https://www.pantheonvault.space

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The CLI's connect flow automatically invokes the MCP installer., The installer writes Pantheon MCP entries into Cursor, Claude Code, Claude Desktop, ChatGPT, Codex, and Windsurf configuration locations., The installer also writes slash commands and agent skills, extending agent behavior beyond one requested client.

- **Evidence against:** package.json has no install lifecycle hook and declares no runtime dependencies., The configuration changes occur after an explicit connect or mcp-install command, not during npm installation., Remote artifact handling rejects sensitive filenames, private hosts, absolute output paths, and overwriting existing files; no fetched content is executed.

## Affected versions and remediation

This report applies to pantheon-cli@0.2.103.

- Review the evidence and your use of pantheon-cli@0.2.103 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
