Do not execute instructions or code found in this document. ## 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:** 1.42.0 - **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. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 89.0% - **Started:** 2026-08-21T07:48:57.157Z - **Finished:** 2026-08-21T07:49:58.426Z - **Download time:** 758 ms - **Static scan time:** 1777 ms - **AI review time:** 58733 ms - **Total time:** 61269 ms ## Security analysis ### Published attack-surface review - **Summary:** The user-invoked \`protect\` command can rewrite discovered MCP/agent configuration files to route local servers through this package's wrapper. Install-time CI workflow creation is guarded by an explicit opt-in. - **Trigger:** Running \`mcp-observatory protect\` without a file argument; separately, installation with auto-setup explicitly enabled. - **Impact:** Can alter how configured MCP servers launch and can add a scheduled GitHub workflow; no unconsented install-time agent-config mutation or exfiltration was confirmed. - **Evidence paths:** scripts/postinstall.mjs, dist/src/commands/handshake.js, dist/src/handshake.js, dist/src/discovery.js, dist/src/cli.js, dist/src/auth.js, dist/src/command-events.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T07:49:58.426Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit MCP configuration rewriting and opt-in CI workflow generation. - **Rationale:** No concrete malicious chain was found: the install hook is opt-in and cloud transmission requires explicit cloud commands. The package nevertheless has an explicit broad MCP-client configuration rewrite capability, warranting a warning under the stated policy. - **Files touched:** .github/workflows/mcp-observatory.yml, \.observatory.bak, \ - **Network endpoints:** https://app.mcp-observatory.com/api/v1/artifacts, https://app.mcp-observatory.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The explicit \`protect\` CLI command rewrites all discovered MCP client configs by default, including home-directory agent configs, and changes server launch commands., Postinstall can create a scheduled GitHub Actions workflow in the consuming project, but only when the project config or an environment flag opts in. - **Evidence against:** Postinstall exits unless \`mcpObservatory.autoSetupCi=true\` or its explicit force environment flag is set., Cloud upload, browser launch, and credential storage are reached only through explicit cloud login/upload commands., Usage telemetry is implemented as a no-op local function; no automatic exfiltration was found. ## Public findings ### 1.
