CAUTION

Publisher claims: "Multi-project MCP router + operator dashboard for Claude Code, Codex, Cursor. Ask any local or SSH-reachable project a question without `cd` — the project's subagent loads its own CLAUDE.md and Serena memories and answers. Ships with a live web console: KPI strip, inter-project network graph, trace waterfall, memory editor, multi-axis budgets. Part of the FleetQ ecosystem." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-01 and scored it 63/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Access to sensitive file paths; Outbound HTTP to raw IP address. Summary: no network, touches nothing outside the project, writes no memory.
