The postinstall hook conditionally creates a GitHub Actions workflow in the consuming project. It is enabled only by explicit project configuration or an environment flag; no unconsented broad AI-agent control-surface write was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-08-18T01:27:40.176Z - **Finished:** 2026-08-18T01:28:48.460Z - **Download time:** 1026 ms - **Static scan time:** 1352 ms - **AI review time:** 65904 ms - **Total time:** 68284 ms ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook conditionally creates a GitHub Actions workflow in the consuming project. It is enabled only by explicit project configuration or an environment flag; no unconsented broad AI-agent control-surface write was confirmed. - **Trigger:** npm install in an MCP project with mcpObservatory.autoSetupCi=true or MCP\_OBSERVATORY\_AUTO\_SETUP\_CI=1 - **Impact:** Adds scheduled vendor CI to 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:** 2026-08-18T01:28:48.460Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** conditional CI workflow creation - **Rationale:** The guarded postinstall project-workflow mutation warrants a warning under the lifecycle policy. Source inspection found no install-time exfiltration, remote payload execution, or broad agent-control hijack. - **Files touched:** scripts/postinstall.mjs, package.json, .github/workflows/mcp-observatory.yml ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Install-time hook can create a project GitHub Actions workflow., The workflow adds scheduled CI invoking the vendor action., The hook only writes when explicit package config or an environment flag enables auto-setup. - **Evidence against:** No install-time network request, credential harvesting, shell execution, or agent-config write found., Cloud upload is an explicit authenticated CLI command for a user-supplied artifact., Target discovery and process execution are scanner functions invoked by CLI commands. ## Public findings ### 1.
