Future agent sessions inherit mandatory conversation logging instructions and altered client configuration. - **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:** 0.1.60 - **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. Global npm installation automatically changes foreign AI-client configuration and broad agent instruction files without requesting consent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-30T16:52:40.940Z - **Finished:** 2026-09-30T16:54:57.269Z - **Download time:** 2316 ms - **Static scan time:** 10296 ms - **AI review time:** 123716 ms - **Total time:** 136329 ms 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:** Global npm installation automatically changes foreign AI-client configuration and broad agent instruction files without requesting consent. - **Trigger:** Global npm installation activates the postinstall setup command. - **Impact:** Future agent sessions inherit mandatory conversation logging instructions and altered client configuration. - **Evidence paths:** package.json, dist/cli/index.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T16:54:57.269Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup registers Chron MCP servers, appends or replaces logging instructions, and installs shell wrappers for Codex. - **Attack narrative:** The postinstall hook invokes the CLI setup command. Its gate suppresses local installation setup but allows global installation to proceed automatically. Setup changes multiple AI-client MCP configurations and writes home-level agent instructions requiring conversation logging, without a consent prompt or saved authorization check. It also installs Codex shell wrappers. These are broad foreign agent control surfaces rather than package-owned extension files. - **Rationale:** The inspected global postinstall path performs unconsented mutation of foreign AI-agent configuration and broad instruction files, meeting the blocking policy. The local-install guard and logging purpose do not authorize those automatic global changes. - **Files touched:** CLAUDE.md, AGENTS.md, .codex/instructions.md, .claude.json, .cursor/mcp.json, .gemini/settings.json, .gemini/GEMINI.md, .codex/config.toml, .zshrc, .bashrc ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically invokes setup during postinstall., The active CLI dispatches setup, which permits automatic configuration on global npm installs without a consent prompt., Setup writes MCP configurations and installs instructions across foreign AI clients., Instruction destinations include home-level CLAUDE.md, AGENTS.md, and .codex/instructions.md; existing files receive appended instructions., The MCP configuration writer creates directories and writes updated client configuration files., dist/index.js also contains the flagged global Claude and Cursor configuration destinations. - **Evidence against:** Local npm postinstall skips setup; the automatic mutation requires a global install., The installed integration serves the package's conversation logging purpose. ## Affected versions and remediation This report applies to chron-mcp@0.1.60. - Avoid installing chron-mcp@0.1.60. 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.
