## Security analysis

### Published attack-surface review

- **Summary:** The npm postinstall hook can retrieve a mutable latest release archive and install its binary payload. It also installs unpinned Python packages into the invoking user's Python environment.

- **Trigger:** npm installation, when the platform binary is absent; Python is present for pip installation

- **Impact:** A compromised release host or dependency resolution path could supply code during installation.

- **Evidence paths:** package.json, postinstall.mjs, bin/tfcode.js, python/tf\_sync/mcp.py

- **Review source:** ai\_review

- **Reviewed:** 2026-08-21T17:35:26.364Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** postinstall remote payload retrieval and user-site pip installation

- **Rationale:** The source has a risky remote install chain and unconsented user-site dependency installation, warranting a warning. It does not show concrete malicious behavior, credential theft, or foreign AI-agent control-surface mutation.

- **Files touched:** postinstall.mjs, bin/tfcode, bin/app/

- **Network endpoints:** gitea.toothfairyai.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** Install hook fetches the latest release version and downloads an archive without an integrity check., Install hook invokes pip with unpinned packages and --user during npm installation., Downloaded archive contents are copied into the package bin directory.

- **Evidence against:** Network use targets the named ToothFairyAI Gitea host and is disclosed by install output., No source evidence of credential harvesting, exfiltration, or foreign AI-agent config writes., MCP synchronization is explicitly unimplemented; it directs users to configure it manually.
