These transmissions are enabled by default and require environment-variable opt-out. - **Trigger:** Starting the package-owned MCP server after setup or client restart. - **Impact:** Remote disclosure of user prompts, tool-result excerpts, social-posting configuration, persona corpus, and subprocess output. - **Evidence paths:** mcp/dist/index.js, scripts/relay\_session\_transcripts.py, mcp/dist/telemetry.js, mcp/install.mjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-04T20:11:49.965Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default background telemetry, log streaming, state sync, and transcript relay - **Attack narrative:** The MCP server starts a default-on relay that reads newly written Claude session transcripts from package-matching project folders, preserves user/assistant text and tool-result excerpts, and posts them to app.s4l.ai. It also sends raw subprocess logs plus configuration and persona-corpus snapshots to package-controlled endpoints; opt-out requires setting undocumented environment flags rather than affirmative consent. - **Rationale:** Source establishes automatic, remote transmission of user content and local operational data after MCP startup. This is concrete data exfiltration, not merely package-aligned network use. - **Files touched:** ~/.claude/projects/\*/\*.jsonl, ~/.social-autoposter-mcp/transcript-relay-state.json, ~/.social-autoposter-mcp/config.json, persona\_corpus.txt, ~/.claude.json, ~/Library/Application Support/Claude/claude\_desktop\_config.json - **Network endpoints:** https://app.s4l.ai/api/v1/installations/logs, https://app.s4l.ai/api/v1/installations/onboarding-events, https://s4l.ai/api/v1/installations/state-snapshot, https://s4l.ai/api/v1/installations/heartbeat, https://4d44ac907262c6545cf8681703528d04@o4507617161314304.ingest.us.sentry.io/4511598804336640 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** mcp/dist/index.js relays Claude session transcripts by default every 5 minutes., scripts/relay\_session\_transcripts.py reads matching ~/.claude/projects/\*.jsonl files and POSTs message text/tool results., mcp/dist/telemetry.js sends config, persona corpus, queues, and onboarding state to s4l.ai., mcp/dist/telemetry.js streams raw pipeline stdout/stderr to app.s4l.ai by default., mcp/install.mjs registers the server in Claude Desktop and Claude Code configs. - **Evidence against:** package.json has no npm preinstall/install/postinstall hook., Transcript relay scopes itself to social-autoposter/s4l-worker project directories., Cookie import is described as an explicit confirmed setup action. ## Public findings ### 1.
