Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The bundle can change foreign coding-agent skill and MCP configuration, but only after the user starts the MCP server and a tool call supplies the action, platform, and token. There is no install-lifecycle hook, hidden recipient, or self-install chain, so this is a guarded agent-control capability rather than an install-time hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 73.0% - **Started:** 2026-09-26T11:43:09.590Z - **Finished:** 2026-09-26T11:44:52.573Z - **Download time:** 1281 ms - **Static scan time:** 1614 ms - **AI review time:** 100087 ms - **Total time:** 102983 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Running the MCP server exposes tools that install skills into Claude or Cursor skill directories and register MCP servers in Claude Code or OpenCode config. Those writes are command-gated, not npm install hooks. - **Trigger:** A user starts the Whalent MCP server with a token, then a client calls whalent\_manage\_skills or whalent\_manage\_mcp. - **Impact:** A connected client can add or remove coding-agent skills and MCP server entries for the selected provider. The package does not perform that mutation at npm install time. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-26T11:44:52.573Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The skill tool downloads files from the configured platform and writes them under the provider skill directory. The MCP tool calls injectMcpServer, which updates .claude.json or opencode.json with the supplied command, args, and env. - **Rationale:** The bundle can change foreign coding-agent skill and MCP configuration, but only after the user starts the MCP server and a tool call supplies the action, platform, and token. There is no install-lifecycle hook, hidden recipient, or self-install chain, so this is a guarded agent-control capability rather than an install-time hijack. - **Files touched:** .claude.json, opencode.json, .cursor - **Network endpoints:** memory.whalent.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 73.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** High - **Evidence for warning:** package.json exposes the whalent bin at dist/index.cjs and has build, start, and test scripts only, with no preinstall, install, or postinstall hook., After the MCP server is running, whalent\_manage\_skills downloads a skill from the caller-supplied platform URL using the supplied bearer token and installs those files., Skill paths are resolved under the user home or workspace platform directory, including the Cursor .cursor tree and the Claude platform directory., whalent\_manage\_mcp registration calls injectMcpServer, which writes a Claude Code or OpenCode MCP server entry that can include command, args, and env., downloadSkillFiles requests platformUrl plus /pt/api/skills/ and sends the supplied token as Authorization. - **Evidence against:** Nothing in package.json runs these writers during npm install; the MCP entry starts only when that file is executed and a token is present., safeSkillFilePath rejects absolute skill paths and paths that escape the skill directory., The download host is the platform URL the operator passed in, and memory.whalent.com is the package-aligned fallback origin. ## Affected versions and remediation This report applies to @whalent/agent@0.3.468. - Review the evidence and your use of @whalent/agent@0.3.468 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
