It establishes an unconsented AI-agent control surface in the consumer workspace and can later execute npx-resolved MCP packages. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.2.15 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Automatic installation mutates the consumer workspace's OpenCode agent, command, and configuration directories. The created configuration enables MCP commands that resolve packages with npx. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-04T06:48:53.467Z - **Finished:** 2026-09-04T06:49:41.551Z - **Download time:** 2649 ms - **Static scan time:** 88 ms - **AI review time:** 45346 ms - **Total time:** 48084 ms ## Security analysis ### Published attack-surface review - **Summary:** Automatic installation mutates the consumer workspace's OpenCode agent, command, and configuration directories. The created configuration enables MCP commands that resolve packages with npx. - **Trigger:** npm installation triggers postinstall. - **Impact:** It establishes an unconsented AI-agent control surface in the consumer workspace and can later execute npx-resolved MCP packages. - **Evidence paths:** package.json, scripts/install.js, opencode.tera.example.json - **Review source:** ai\_review - **Reviewed:** 2026-09-04T06:49:41.551Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies a broad AI-agent extension and enabled MCP configuration into the consumer project. - **Attack narrative:** Installing the package runs scripts/install.js in the npm caller's workspace. It copies the package's agents and commands into .opencode, creates an OpenCode configuration if absent, and enables MCP entries whose commands use npx -y. This is an automatic mutation of a broad AI-agent control surface rather than an explicit user setup action. - **Rationale:** The automatic postinstall writes enabled agent-control configuration and a broad set of agent content into the consuming project. Existing-file conflict handling does not provide consent for creating this control surface when it is absent. - **Files touched:** scripts/install.js, .opencode/agents/, .opencode/commands/, .opencode/opencode.json, .opencode/opencode.tera.example.json, tera-system/, tools/, .tera/license.state.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs its installer automatically after npm installation., The installer targets the consumer workspace and copies agent and command content into its OpenCode control directories., When no configuration exists, installation creates an enabled OpenCode MCP configuration that runs packages through npx. - **Evidence against:** The installer preserves differing existing configuration files and records conflicts., No credential exfiltration or non-local network request was found in the lifecycle installer. ## Public findings ### 1.
