The user-started CLI runs a local bridge that invokes configured AI CLIs and communicates with its configured WeChat/relay services. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 91.0% - **Started:** 2026-07-12T03:47:28.410Z - **Finished:** 2026-07-12T03:48:39.834Z - **Download time:** 517 ms - **Static scan time:** 662 ms - **AI review time:** 70244 ms - **Total time:** 71424 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The user-started CLI runs a local bridge that invokes configured AI CLIs and communicates with its configured WeChat/relay services. - **Trigger:** User installs and explicitly runs the \`claude-codex-wechat\` CLI or MCP server. - **Impact:** Can process bridge conversations, invoke configured provider commands, and send user-selected/downloaded media through the configured channel. - **Evidence paths:** package.json, dist/server/cli.js, dist/mcp/mediaServer.js, dist/mcp/scripts/douyin-download.mjs, config.example.json - **Review source:** ai\_review - **Reviewed:** 2026-07-12T03:48:39.834Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-configured AI-command bridge with WeChat media relay and optional video download. - **Rationale:** The scanner's remote decoded-payload claim is not supported by the inspected source. Shipped behavior is a package-aligned, explicitly invoked WeChat-to-Claude/Codex bridge with no install-time execution or concrete exfiltration/payload chain. - **Files touched:** package.json, config.example.json, dist/server/cli.js, dist/mcp/mediaServer.js, dist/mcp/scripts/douyin-download.mjs - **Network endpoints:** https://ilinkai.weixin.qq.com, wss://wechat.style520.com/agent, http://localhost:8787, https://www.iesdouyin.com, https://aweme.snssdk.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** \`dist/server/cli.js\` can spawn configured Claude/Codex commands during its user-started bridge runtime., \`dist/mcp/mediaServer.js\` exposes MCP tools that send selected files through the local bridge and run its bundled Douyin downloader. - **Evidence against:** \`package.json\` has no preinstall/install/postinstall hook; \`prepublishOnly\` only builds before publishing., No eval, Function constructor, encoded-payload decoding, or dynamic remote-code execution found in shipped runtime files., \`dist/mcp/mediaServer.js\` uses \`execFile\` with the packaged downloader path and argument array, not shell interpolation., Network use is aligned with the stated WeChat bridge, optional relay, local API, and explicit Douyin download feature., Config writes target the package-owned \`~/.claude-codex-wechat/config.json\`, not broad Claude/Codex control files. ## Public findings ### 1.
