Changes agent instructions and tool authorization across foreign AI clients without explicit setup consent. - **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:** 0.20.0 - **Selected version is latest:** Yes - **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. The npm postinstall hook automatically modifies multiple AI clients' configuration and instruction files. Codex setup also changes tool approval settings without a consent prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-02T10:57:25.383Z - **Finished:** 2026-10-02T10:59:11.433Z - **Download time:** 1531 ms - **Static scan time:** 4768 ms - **AI review time:** 99749 ms - **Total time:** 106050 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:** The npm postinstall hook automatically modifies multiple AI clients' configuration and instruction files. Codex setup also changes tool approval settings without a consent prompt. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** Changes agent instructions and tool authorization across foreign AI clients without explicit setup consent. - **Evidence paths:** package.json, dist/cli/commands-admin.js, dist/cli/setup.js, dist/cli/setup/codex.js, dist/cli/setup/rules.js - **Review source:** ai\_review - **Reviewed:** 2026-10-02T10:59:11.433Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes setup all; default options enable rules and hooks, and platform handlers write agent configuration and package instructions. - **Attack narrative:** An ordinary npm installation invokes setup for all supported AI clients. Rules and hooks default to enabled, and the setup path writes global client configuration and agent instruction files without prompting. Codex setup removes per-tool approval overrides and generates automatic approval for CodeSift tools. These automatic changes cross into foreign agent control surfaces. - **Rationale:** Inspected source proves unconsented postinstall mutation of broad, foreign AI-agent control surfaces, including instruction files and tool approval configuration. This meets the blocking policy independently of scanner similarity labels. - **Files touched:** .codex/config.toml, AGENTS.md, GEMINI.md, .claude/rules/codesift.md, .cursor/rules/codesift.mdc ### 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 runs setup all during postinstall, suppressing error output., dist/cli/commands-admin.js enables hooks and rules by default and runs setup across supported platforms without a consent prompt., dist/cli/setup.js invokes platform configuration handlers and installs rules using the user's home directory., dist/cli/setup/codex.js writes global Codex configuration and removes existing per-tool approval overrides; its generated configuration automatically approves CodeSift tools., dist/cli/setup/rules.js appends or replaces package instructions in AGENTS.md and GEMINI.md and installs rules in global client directories. - **Evidence against:** The configuration changes integrate the package's own MCP server, but occur automatically during npm installation rather than an explicitly requested setup command. ## Affected versions and remediation This report applies to codesift-mcp@0.20.0. - Avoid installing codesift-mcp@0.20.0. 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.
