Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection shows sensitive primitives are aligned with the package's documented MCP memory, setup, HUD, and migration features and are activated by explicit commands or tool calls, not lifecycle or hidden import-time behavior. The scanner's dangerous-delta and network findings are real capability changes but do not establish unconsented execution or exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-07-01T02:09:04.521Z - **Finished:** 2026-07-01T02:10:05.640Z - **Download time:** 1267 ms - **Static scan time:** 1034 ms - **AI review time:** 58817 ms - **Total time:** 61119 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:** No confirmed malicious attack surface. The package is an EchoMem MCP bridge with user-invoked setup, login, HUD, report, sync, and migration flows that access local agent logs and EchoMem APIs. - **Trigger:** User runs echomem-mcp/echomem-hud commands or MCP tools; no install-time trigger. - **Impact:** Can store credentials locally, configure supported MCP clients, read local agent transcripts, and send selected EchoMem data to package-aligned APIs when invoked. - **Evidence paths:** package.json, dist/index.js, dist/setup.js, dist/keystore.js, dist/events.js, dist/migrate.js, dist/codex-sync.js, dist/hud/hooks.js, dist/hud/cli.js, dist/hud/adapters.js - **Review source:** ai\_review - **Reviewed:** 2026-07-01T02:10:05.640Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated MCP bridge plus optional local setup, telemetry, HUD, and migration utilities. - **Rationale:** Static inspection shows sensitive primitives are aligned with the package's documented MCP memory, setup, HUD, and migration features and are activated by explicit commands or tool calls, not lifecycle or hidden import-time behavior. The scanner's dangerous-delta and network findings are real capability changes but do not establish unconsented execution or exfiltration. - **Files touched:** ~/.echomem/credentials.json, ~/.echomem/events.jsonl, ~/.echomem/migrate-ledger.json, ~/.echomem/migrate-metrics.jsonl, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/Library/Application Support/Claude/claude\_desktop\_config.json - **Network endpoints:** https://echo-mem-chrome.vercel.app, https://memory-feed.vercel.app, https://yeahecho.com ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** dist/setup.js can write MCP client configs and Codex config, but only via setup/update subcommands., dist/hud/hooks.js can write Codex hook config, but only via echomem-hud install-hooks., dist/migrate.js and dist/codex-sync.js can read local Codex/Claude logs and upload summaries/transcripts after explicit sync/migrate actions. - **Evidence against:** package.json has no install/preinstall/postinstall lifecycle hooks., dist/index.js starts an MCP stdio server; no import-time config mutation beyond serving when bin is run., Network endpoints are package-aligned EchoMem services: echo-mem-chrome.vercel.app, memory-feed.vercel.app, yeahecho.com., Keystore writes are documented local credentials under ~/.echomem with 0600-style permissions., No eval/Function/native binary loader or hidden staged payload found; shipped wasm/riv assets are HUD/city UI assets. ## Affected versions and remediation This report applies to @echomem/mcp@1.4.3. - Review the evidence and your use of @echomem/mcp@1.4.3 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
