Agent behavior and configuration can be changed during package installation without the user explicitly invoking setup. - **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:** 0.21.1 - **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. The postinstall chain invokes setup across multiple agent platforms with hooks and rules enabled by default, changing agent configuration without an explicit user setup command. This matches the policy for blocking unconsented postinstall mutation of broad AI-agent control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-09T11:29:12.563Z - **Finished:** 2026-10-09T11:30:16.095Z - **Download time:** 5371 ms - **Static scan time:** 4592 ms - **AI review time:** 53567 ms - **Total time:** 63532 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 configures multiple AI agent platforms. It writes agent configuration and hooks without an explicit setup command, and Codex setup can alter approval settings for this package's tools. - **Trigger:** Installing the package with npm and its lifecycle scripts enabled. - **Impact:** Agent behavior and configuration can be changed during package installation without the user explicitly invoking setup. - **Evidence paths:** package.json, dist/postinstall.js, dist/cli/commands-admin.js, dist/cli/setup.js, dist/cli/setup/codex.js, dist/cli/setup/rules.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T11:30:16.095Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall runs \`setup all\`; setup defaults enable hooks and rules, and iterates over supported platforms to write their configuration. - **Attack narrative:** During npm installation, the package automatically runs setup across several AI agent platforms. The setup defaults enable hooks and rules and write agent configuration, including Codex settings. This is an unconsented install-time mutation of broad agent control surfaces. - **Rationale:** The postinstall chain invokes setup across multiple agent platforms with hooks and rules enabled by default, changing agent configuration without an explicit user setup command. This matches the policy for blocking unconsented postinstall mutation of broad AI-agent control surfaces. - **Files touched:** package.json, dist/postinstall.js, dist/cli/commands-admin.js, dist/cli/setup.js, dist/cli/setup/codex.js, dist/cli/setup/rules.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs postinstall.mjs automatically during npm installation., The postinstall script launches \`codesift setup all\` without setup flags., Setup defaults enable hooks and rules, and \`all\` iterates across six agent platforms., Platform setup writes agent hooks and rules; Claude setup also installs global instructions., Codex setup writes its config under \`.codex\` and can change approval settings for CodeSift tools., Rules setup targets agent rule files and, for some platforms, appends to project instruction files. - **Evidence against:** The changes configure this package as an MCP server, which aligns with its stated product purpose. ## Affected versions and remediation This report applies to codesift-mcp@0.21.1. - Avoid installing codesift-mcp@0.21.1. 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.
