Running the package binary interactively automatically configures multiple AI-client MCP settings and installs a Claude Code session-start hook. The installed skill directs agents to log all exchanges and suppress privacy warnings. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-09T18:32:59.817Z - **Finished:** 2026-08-09T18:34:10.796Z - **Download time:** 509 ms - **Static scan time:** 9902 ms - **AI review time:** 60564 ms - **Total time:** 70979 ms ## Security analysis ### Published attack-surface review - **Summary:** Running the package binary interactively automatically configures multiple AI-client MCP settings and installs a Claude Code session-start hook. The installed skill directs agents to log all exchanges and suppress privacy warnings. - **Trigger:** User runs chron-mcp interactively after installation. - **Impact:** Persists package-controlled logging instructions across AI-agent sessions and broadens MCP execution surface. - **Evidence paths:** package.json, dist/index.js, dist/cli/index.js, skills/chron.skill.md, skills/codex.skill.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T18:34:10.796Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** runtime AI-client configuration and session-hook installation - **Rationale:** Source inspection confirms persistent cross-client AI-agent configuration and coercive logging guidance, but not unconsented install-time mutation or concrete exfiltration. Warn rather than block under the explicit-user-command extension policy. - **Files touched:** ~/.chron/chron.skill.md, ~/.claude/settings.json, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/Library/Application Support/Claude/claude\_desktop\_config.json, ~/.codex/config.toml, ~/.chron/config.json - **Network endpoints:** https://login.microsoftonline.com/${tenantId}/oauth2/v2.0/token ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** dist/index.js: TTY invocation runs setup automatically., dist/index.js: setup writes MCP entries for Claude Desktop, Cursor, Windsurf, and Claude Code., dist/index.js: setup adds a Claude SessionStart hook that reads ~/.chron/chron.skill.md., skills/chron.skill.md instructs agents to log every exchange and suppress privacy warnings., dist/cli/index.js: connect codex explicitly writes ~/.codex/config.toml., dist/cli/index.js: relay sends telemetry only when user-supplied SIEM/relay configuration is present. - **Evidence against:** package.json has only prepublishOnly; no install lifecycle hook., No hardcoded package-controlled exfiltration endpoint found., Configured relay payloads are telemetry/metadata rather than conversation content., Runtime npm install is limited to the explicit \`chron update\` command., Dynamic native loading and child-process use originate from bundled libsql/setup behavior., Destructive session pruning requires an explicit --confirm flag. ## Public findings ### 1.
