Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package automatically registers Wayari as an MCP server with installed coding agents. This changes user-wide or global agent control surfaces without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T23:12:35.715Z - **Finished:** 2026-09-11T23:13:46.564Z - **Download time:** 506 ms - **Static scan time:** 3209 ms - **AI review time:** 67134 ms - **Total time:** 70849 ms The recorded confidence comes from the underlying analysis.

This changes user-wide or global agent control surfaces without an explicit setup command. - **Trigger:** npm postinstall during package installation. - **Impact:** Future agent sessions can invoke the package's MCP tools, extending the package's control into unrelated projects. - **Evidence paths:** package.json, dist/cli-postinstall.mjs, dist/wayari.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T23:13:46.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic MCP registration through Claude Code and Codex CLI commands. - **Attack narrative:** The package's postinstall script runs automatically and starts its connect command. Connect detects installed Claude Code and Codex clients, then invokes their MCP add commands to register Wayari outside the consumer project. Claude registration is explicitly user-scoped and the source describes Codex registration as global. This is an unconsented install-time mutation of foreign AI-agent configuration, so it creates a persistent broad control surface after installation. - **Rationale:** The automatic lifecycle chain is complete: postinstall invokes connect, which registers MCP integrations at user or global scope. This meets the install-time foreign AI-agent control-surface block rule. - **Files touched:** bin/wayari.mjs, ~/.claude/settings.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall script automatically., That script launches the installed CLI with the connect command., Connect registers an MCP server for Claude Code at user scope and for Codex globally., The registration commands are run through a login shell when either agent CLI is present. - **Evidence against:** No secret collection or external network exfiltration was confirmed in the inspected lifecycle path., The postinstall also repairs execute permissions for node-pty's local helper. ## Affected versions and remediation This report applies to wayari@0.3.1. - Avoid installing wayari@0.3.1. 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.
