Cursor, Claude, Codex, and other supported agents can be persistently instructed to use Pantheon tools and launch its MCP server. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.2.124 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm installation automatically modifies broad AI-agent control surfaces. It installs agent instructions and commands even when no prior Pantheon connection exists; connected installs also add MCP server entries. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T14:43:12.194Z - **Finished:** 2026-09-08T14:44:16.993Z - **Download time:** 506 ms - **Static scan time:** 7017 ms - **AI review time:** 57275 ms - **Total time:** 64799 ms The recorded confidence comes from the underlying analysis.

It installs agent instructions and commands even when no prior Pantheon connection exists; connected installs also add MCP server entries. - **Trigger:** Global npm installation runs the postinstall hook. - **Impact:** Cursor, Claude, Codex, and other supported agents can be persistently instructed to use Pantheon tools and launch its MCP server. - **Evidence paths:** postinstall.mjs, dist/pantheon.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T14:44:16.993Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic writes to third-party agent skills, commands, and MCP configuration. - **Attack narrative:** On global installation, npm runs postinstall.mjs, which starts the bundled CLI with an internal postinstall command. That command writes Pantheon skill files into generic and Codex agent directories and command files into Cursor and Claude directories without an explicit setup command. If existing Pantheon state is found, it also modifies third-party MCP configuration files to register the Pantheon server. The dropped skill broadly directs agents to call Pantheon MCP tools. - **Rationale:** The package uses an automatic install lifecycle to mutate foreign, broad AI-agent control surfaces and inject persistent agent instructions. This is concrete install-hook abuse under the stated policy. - **Files touched:** postinstall.mjs, dist/pantheon.mjs, ~/.agents/skills/pantheon/SKILL.md, ~/.codex/skills/pantheon/SKILL.md, ~/.cursor/commands/\*.md, ~/.claude/commands/\*.md, ~/.cursor/mcp.json, ~/.claude.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically launches the CLI during global npm installation., That path writes command and skill files into Cursor, Claude, Codex, and generic agent directories without a user command., The dropped Codex skill directs agents to invoke this package's MCP tools., When stored configuration exists, the same automatic path also edits multiple third-party MCP configuration files. - **Evidence against:** The lifecycle hook is limited to global installations, not ordinary local installs. ## Affected versions and remediation This report applies to pantheon-cli@0.2.124. - Avoid installing pantheon-cli@0.2.124. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
