## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 4.16.3
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Review flagged AI-agent configuration or capability changes. 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.

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious install-time control-surface mutation occurs. The explicit setup command installs a first-party governance MCP server and grants it broad assistant-tool approval.

- **Trigger:** User runs \`delimit setup\`.

- **Impact:** Configured Claude Code/Codex sessions can invoke Delimit MCP tools without normal per-tool approval.

- **Evidence paths:** package.json, scripts/postinstall.js, bin/delimit-setup.js, lib/cross-model-hooks.js, gateway/ai/backends/tools\_infra.py

- **Review source:** ai\_review

- **Reviewed:** 2026-07-18T20:12:24.351Z

### AI review details

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

- **Mechanism:** Explicit AI-agent MCP registration, auto-approval, self-update, and artifact download.

- **Rationale:** No concrete malicious chain was found, but explicit setup modifies multiple AI-agent control surfaces and disables per-tool approval for its MCP server. Warn rather than block under the explicit-user-command policy.

- **Files touched:** scripts/postinstall.js, bin/delimit-setup.js, lib/cross-model-hooks.js, gateway/ai/backends/tools\_infra.py

- **Network endpoints:** https://delimit.ai/api/telemetry, https://delimit.ai/releases/, https://github.com/delimit-ai/delimit-gateway.git

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** \`scripts/postinstall.js\` POSTs install metadata to \`https://delimit.ai/api/telemetry\` unless opted out., \`bin/delimit-setup.js\` writes MCP registrations and auto-approval settings for Claude Code and Codex., \`bin/delimit-setup.js\` sets Codex Delimit MCP \`approval\_policy = "never"\`., Explicit \`delimit setup\` self-updates with \`npm install -g delimit-cli@latest\` and downloads/releases extracts a Pro artifact.

- **Evidence against:** The \`postinstall\` hook only prints and sends best-effort package/version/platform telemetry; it does not invoke setup or write agent config., Agent configuration changes are reached through the explicit \`delimit setup\` command, not npm lifecycle execution., Observed endpoints are Delimit/GitHub package-aligned; no source-confirmed credential harvesting or exfiltration chain was found., \`gateway/ai/backends/tools\_infra.py\` contains secret-detection regexes, not embedded credential values.
