Remote or bundled vault content can be installed into agent instruction surfaces without an explicit per-start user approval step; old managed files can also be pruned via manifest. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.3.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Although much of the behavior is package-aligned and documented, the default MCP-server startup path performs unconsented AI-agent control-surface writes from a remote-controlled vault/fallback bundle. Under the firewall decision boundary, that is concrete enough to block as AI-agent control hijack risk. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-07-03T07:19:33.463Z - **Finished:** 2026-07-03T07:20:22.547Z - **Download time:** 501 ms - **Static scan time:** 265 ms - **AI review time:** 48317 ms - **Total time:** 49084 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:** The MCP server mutates AI-agent control surfaces during normal runtime by default. It can pull remote approved vault content from Supabase and write it into ~/.claude or ~/.codex skills/prompts/commands, giving remote content influence over agent instructions. - **Trigger:** Starting the noclaf-mcp MCP server after it is configured in an AI client. - **Impact:** Remote or bundled vault content can be installed into agent instruction surfaces without an explicit per-start user approval step; old managed files can also be pruned via manifest. - **Evidence paths:** package.json, dist/mcp-server.js, dist/lib/vault-source.js, dist/lib/provision.js, dist/lib/targets.js, dist/constants.js, dist/auth.js, dist/lib/dependencies.js - **Review source:** ai\_review - **Reviewed:** 2026-07-03T07:20:22.547Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default runtime auto-pull of remote/bundled agent instructions into AI client directories - **Attack narrative:** When an AI client launches noclaf-mcp, the server authenticates if possible, loads vault documents from Supabase or the bundle, then auto-provisions commands/skills/agents into Claude or Codex directories unless disabled by environment. This is a default runtime mutation of AI-agent instruction surfaces and can source content from a remote service. - **Rationale:** Although much of the behavior is package-aligned and documented, the default MCP-server startup path performs unconsented AI-agent control-surface writes from a remote-controlled vault/fallback bundle. Under the firewall decision boundary, that is concrete enough to block as AI-agent control hijack risk. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** ~/.claude/commands, ~/.claude/skills, ~/.claude/agents, ~/.claude/.noclaf-provision.json, ~/.codex/skills, ~/.codex/prompts, ~/.codex/.noclaf-provision.json - **Network endpoints:** https://wdshvtlsjoegjvmpqobx.supabase.co, https://wdshvtlsjoegjvmpqobx.supabase.co/functions/v1/mcp-token-exchange ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** dist/mcp-server.js runs auto-pull on MCP server startup unless NOCLAF\_AUTO\_PULL is 0/false., dist/mcp-server.js chooses claudeTarget or codexTarget from NOCLAF\_CLIENT and calls pullVault after server connect., dist/lib/vault-source.js fetches approved ai\_vault\_docs from Supabase and falls back to bundled docs., dist/lib/provision.js writes/prunes commands, skills, and agents under the target agent directory with a manifest., dist/lib/targets.js maps Claude to ~/.claude and Codex to ~/.codex skills/prompts., dist/constants.js hardcodes Supabase host and token-exchange endpoint for remote vault/auth. - **Evidence against:** package.json has no install/postinstall lifecycle hook; prepublishOnly is publisher-side build only., Credential handling is user-invoked login/env PAT and exchanges only with the package's Supabase service., dist/lib/dependencies.js avoids shell interpolation and only runs dependency installs after CLI confirmation or -y., Bundled skills/commands are visible markdown, mostly workflow/spec helpers, not hidden payloads. ## Affected versions and remediation This report applies to @noclaf/mcp@0.3.6. - Avoid installing @noclaf/mcp@0.3.6. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
