Explicit \`claude-codex-wechat start\` creates a first-party local daemon and an MCP configuration that exposes file-send and video-download tools to configured Claude/Codex sessions. Those tools can transfer selected local files to the active WeChat chat; this is an intentional but powerful agent-extension capability, not install-time malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-07-12T01:30:35.284Z - **Finished:** 2026-07-12T01:32:16.319Z - **Download time:** 254 ms - **Static scan time:** 644 ms - **AI review time:** 100136 ms - **Total time:** 101035 ms ## Security analysis ### Published attack-surface review - **Summary:** Explicit \`claude-codex-wechat start\` creates a first-party local daemon and an MCP configuration that exposes file-send and video-download tools to configured Claude/Codex sessions. Those tools can transfer selected local files to the active WeChat chat; this is an intentional but powerful agent-extension capability, not install-time malware. - **Trigger:** User runs \`claude-codex-wechat start\` and uses the configured Claude/Codex bridge. - **Impact:** A compromised or prompt-injected configured agent could use the installed MCP tools to send accessible files to the connected WeChat account. - **Evidence paths:** package.json, dist/server/cli.js, dist/mcp/mediaServer.js, dist/mcp/scripts/douyin-download.mjs, config.example.json, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-12T01:32:16.319Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked daemon persistence plus MCP-mediated local file transfer. - **Rationale:** The scanner's remote-decode-and-execute claim is unsupported by the shipped CLI: no dynamic code execution path was found. The package intentionally provisions a powerful first-party MCP extension and user daemon only through explicit runtime commands, so it warrants a warning rather than a malware block. - **Files touched:** ~/.claude-codex-wechat/config.json, ~/.claude-codex-wechat/mcp-media.json, ~/.claude-codex-wechat/media, ~/Library/LaunchAgents/com.claude-codex-wechat.bridge.plist, ~/.config/systemd/user/claude-codex-wechat.service, ~/Downloads - **Network endpoints:** https://ilinkai.weixin.qq.com, https://registry.npmmirror.com/claude-codex-wechat/latest, http://localhost:8787, wss://wechat.style520.com/agent, https://www.iesdouyin.com, https://aweme.snssdk.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`dist/server/cli.js\` explicitly creates an MCP config that launches its bundled media server., \`dist/mcp/mediaServer.js\` accepts arbitrary file paths from MCP tools and asks the local bridge to send them to the active WeChat chat., \`dist/server/cli.js\` installs a user-level launchd/systemd service when the user runs \`start\`., \`dist/mcp/scripts/douyin-download.mjs\` downloads requested Douyin videos and the MCP flow sends them to WeChat. - **Evidence against:** \`package.json\` has no preinstall, install, or postinstall lifecycle hook; \`prepublishOnly\` only builds before publishing., \`dist/server/cli.js\` has no eval, vm, Function, remote import, or decoded-payload execution path., Process spawning targets configured/local Claude or Codex CLIs, service utilities, and the packaged downloader., Network use is feature-aligned: WeChat API, configured relay, package update check, localhost bridge, and Douyin downloads., Service installation and MCP configuration occur only after explicit CLI \`start\`/runtime execution, not package installation. ## Public findings ### 1.
