An opt-in postinstall helper can add a project GitHub Actions workflow. Separate explicit CLI commands can inspect or rewrite MCP client configurations. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-21T07:48:57.336Z - **Finished:** 2026-08-21T07:50:11.739Z - **Download time:** 751 ms - **Static scan time:** 1608 ms - **AI review time:** 72042 ms - **Total time:** 74403 ms ## Security analysis ### Published attack-surface review - **Summary:** An opt-in postinstall helper can add a project GitHub Actions workflow. Separate explicit CLI commands can inspect or rewrite MCP client configurations. - **Trigger:** Install with mcpObservatory.autoSetupCi=true or MCP\_OBSERVATORY\_AUTO\_SETUP\_CI=1; alternatively run protect. - **Impact:** Adds CI automation or changes configured MCP server launch commands; no unconsented install-time control-surface mutation was confirmed. - **Evidence paths:** scripts/postinstall.mjs, dist/src/handshake.js, dist/src/cli.js, dist/src/auth.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T07:50:11.739Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Opt-in CI workflow generation and explicit MCP-config wrapping. - **Rationale:** The package has a guarded lifecycle-based CI mutation and explicit broad MCP-config mutation capability, warranting a warning. Source inspection found no concrete malicious chain, hidden exfiltration, or remote payload execution. - **Files touched:** scripts/postinstall.mjs, project/package.json, project/.github/workflows/mcp-observatory.yml, dist/src/handshake.js, MCP client config files, \.observatory.bak - **Network endpoints:** https://app.mcp-observatory.com/api/v1/artifacts ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall can create a GitHub Actions workflow in the installing project., The write is gated by explicit mcpObservatory.autoSetupCi=true or an environment flag., Explicit protect command rewrites discovered MCP client configs, with backups. - **Evidence against:** Default postinstall only logs guidance; it exits unless the opt-in gate is set., Cloud upload/auth flows are exposed only through explicit CLI commands., No hidden payload, obfuscated execution, or install-time network request was found. ## Public findings ### 1.
