Installation can add Astra-owned skills, commands, and a local stdio MCP registration to detected AI-agent environments. This is an automatic extension setup, not a confirmed remote-control or exfiltration chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-27T04:23:21.991Z - **Finished:** 2026-08-27T04:24:34.618Z - **Download time:** 259 ms - **Static scan time:** 1080 ms - **AI review time:** 71287 ms - **Total time:** 72627 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation can add Astra-owned skills, commands, and a local stdio MCP registration to detected AI-agent environments. This is an automatic extension setup, not a confirmed remote-control or exfiltration chain. - **Trigger:** npm installation when a supported agent CLI is present. - **Impact:** It changes user-level Claude, Codex, or Factory agent configuration and can make the bundled MCP tools available in later agent sessions. - **Evidence paths:** package.json, bin/astra.mjs, lib/rolemap.mjs, lib/mcp-server.mjs, visualizer/server.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-27T04:24:34.618Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall deployment of a package-owned agent extension and MCP server. - **Rationale:** This is a real lifecycle-based agent-extension risk because postinstall modifies user-level AI-agent configuration. The inspected source does not show remote payload delivery, credential theft, destructive behavior, or exfiltration, so blocking as malicious is not justified. - **Files touched:** ~/.claude/skills, ~/.claude/commands, ~/.codex/skills, ~/.codex/prompts, ~/.codex/config.toml, ~/.factory/skills, ~/.factory/commands, ~/.factory/mcp.json, lib/mcp-server.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook runs the installer automatically., The installer copies bundled skills and commands into detected Claude, Codex, and Factory user directories., The installer registers a package-owned stdio MCP server with detected agent CLIs or Factory. - **Evidence against:** The MCP configuration starts the bundled local server through Node and contains no remote endpoint., Existing MCP entries with the same name but different settings are left unchanged., Legacy skill removal is limited to single-file directories whose content hash is allowlisted., No outbound network or credential-exfiltration code was found; the only server is a local visualizer. ## Public findings ### 1.
