Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. The project’s MCP client can load the registered server and expose its tools. - **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:** 8.1.3 - **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. The manifest activates a postinstall script that modifies the consumer project’s MCP configuration and registers this package’s server by default. This is unconsented install-time mutation of an AI-agent control surface, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-21T05:15:23.766Z - **Finished:** 2026-10-21T05:17:20.222Z - **Download time:** 3065 ms - **Static scan time:** 77913 ms - **AI review time:** 35477 ms - **Total time:** 116456 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 install hook changes project-level MCP configuration and registers this package’s server without requiring affirmative setup consent. - **Trigger:** Installing the package with lifecycle scripts enabled, unless the consumer has set the opt-out variable. - **Impact:** The project’s MCP client can load the registered server and expose its tools. - **Evidence paths:** package.json, scripts/postinstall-mcp.js, dist/mcp-server/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T05:17:20.222Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook writes an Exosphere server entry to the consuming project’s \`.mcp.json\`, launching the package’s MCP server with Node. - **Attack narrative:** During package installation, the postinstall hook adds or updates an Exosphere server entry in the consuming project’s \`.mcp.json\`. That entry launches this package’s MCP server, which exposes tools to the configured MCP client. An environment variable can skip setup, but installation performs the configuration change by default. - **Rationale:** The manifest activates a postinstall script that modifies the consumer project’s MCP configuration and registers this package’s server by default. This is unconsented install-time mutation of an AI-agent control surface, so the package should be blocked. - **Files touched:** .mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook runs the MCP setup script automatically., The script targets the consuming project’s \`.mcp.json\` and registers a command that launches this package’s MCP server., The script writes the registration into the project configuration; the server exposes MCP tools. - **Evidence against:** The setup can be skipped with an environment variable, but the default install path performs the configuration write. ## Affected versions and remediation This report applies to @boomi/exosphere@8.1.3. - Avoid installing @boomi/exosphere@8.1.3. 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.
