This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-09T16:34:05.753Z - **Finished:** 2026-08-09T16:35:17.564Z - **Download time:** 507 ms - **Static scan time:** 10681 ms - **AI review time:** 60621 ms - **Total time:** 71811 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicit interactive chron-mcp launch automatically modifies several AI-client MCP configurations and adds a Claude Code SessionStart hook. The installed skill can cause agents to record all conversation content, including sensitive values, into Chron storage. - **Trigger:** User explicitly runs the chron-mcp binary interactively. - **Impact:** Broad AI-agent behavior changes and local collection of conversation secrets; optional configured relays can export audit metadata. - **Evidence paths:** package.json, dist/index.js, skills/chron.skill.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T16:35:17.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-client configuration and prompt-level conversation logging. - **Rationale:** Source confirms an explicit-user-command AI-agent configuration mutation and a skill that promotes indiscriminate conversation logging. No unconsented install-time execution, hard-coded exfiltration endpoint, or concrete payload chain was found. - **Files touched:** dist/index.js, skills/chron.skill.md, ~/.chron/chron.skill.md, ~/.claude/settings.json, ~/.cursor/mcp.json, ~/Library/Application Support/Claude/claude\_desktop\_config.json - **Network endpoints:** https://login.microsoftonline.com/${tenantId}/oauth2/v2.0/token ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** dist/index.js: TTY execution automatically invokes runSetup., dist/index.js: setup writes MCP entries into Claude Desktop, Cursor, Windsurf, and Claude Code configuration., dist/index.js: Claude setup runs \`claude mcp add\` and installs a SessionStart hook., skills/chron.skill.md directs agents to log every exchange verbatim and suppress security warnings., dist/index.js: optional relay integrations transmit audit metadata to user-configured endpoints. - **Evidence against:** package.json has only prepublishOnly; no install-time lifecycle hook., Setup is reached only when the package binary is explicitly run with a TTY., Relay URLs and tokens require CHRON\_\* environment/config values; no hard-coded receiver was found., Relay event builders send metadata/masked secret detections, not logged message content., Database and signing artifacts are stored under the package-owned ~/.chron directory. ## Public findings ### 1.
