VERIFIEDPublisher claims: "Personal library and AI context vault with durable page snapshots, hybrid search, and a remote MCP server (46 tools) for Claude Desktop, Cursor, Windsurf, and Claude Code. Open source, AGPL-3.0, runs on Cloudflare Workers." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Is [email protected] safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario) on 2026-11-06 and scored it 85/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.
