The postinstall hook can add a scheduled GitHub Actions workflow to an MCP project, but only after explicit auto-setup configuration or an environment flag. No unconsented agent-control mutation or exfiltration was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-18T01:45:30.018Z - **Finished:** 2026-08-18T01:46:21.105Z - **Download time:** 1030 ms - **Static scan time:** 1640 ms - **AI review time:** 48415 ms - **Total time:** 51087 ms ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook can add a scheduled GitHub Actions workflow to an MCP project, but only after explicit auto-setup configuration or an environment flag. No unconsented agent-control mutation or exfiltration was established. - **Trigger:** npm install with mcpObservatory.autoSetupCi=true or MCP\_OBSERVATORY\_AUTO\_SETUP\_CI=1 - **Impact:** Adds recurring CI execution of the vendor action in the project repository. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/src/cli.js, dist/src/auth.js, dist/src/discovery.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T01:46:21.105Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded creation of a vendor GitHub Actions workflow - **Rationale:** This is a guarded install-time CI extension with persistent repository effects, so it warrants a warning under the lifecycle-risk policy. It is not concrete malicious behavior because setup is opt-in and source shows no install-time exfiltration or broad AI-agent control-surface mutation. - **Files touched:** scripts/postinstall.mjs, package.json, .github/workflows/mcp-observatory.yml ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Install lifecycle hook can create a scheduled GitHub Actions workflow in the consuming project., The generated workflow invokes the vendor action on push, PRs, and a weekly schedule., Auto-creation is gated by an explicit package config or environment flag and does not overwrite an existing workflow. - **Evidence against:** No install-time network request, credential collection, shell execution, or AI-agent config write was found., Cloud authentication and artifact upload occur only through explicit CLI cloud commands., Agent configuration discovery is runtime scanner functionality, not an install-time mutation. ## Public findings ### 1.
