It can control agent behavior and alter project instructions, commit hooks, CI files, and package scripts. - **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:** 1.17.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package can alter the consumer project's AI-agent hooks and development controls. The writes occur without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-28T09:28:43.405Z - **Finished:** 2026-08-28T09:30:48.050Z - **Download time:** 279 ms - **Static scan time:** 1216 ms - **AI review time:** 123147 ms - **Total time:** 124645 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package can alter the consumer project's AI-agent hooks and development controls. The writes occur without an explicit setup command. - **Trigger:** npm automatically runs postinstall in a project detected as a Suppa application. - **Impact:** It can control agent behavior and alter project instructions, commit hooks, CI files, and package scripts. - **Evidence paths:** package.json, skills/suppa-entity-code/scripts/postinstall.mjs, skills/suppa-entity-code/scripts/install-entity-code-guards.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T09:30:48.050Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A lifecycle script invokes a project-mutating guard installer. - **Attack narrative:** On installation, the package uses postinstall to execute an installer in the consumer repository. When that repository is detected as a Suppa application, the installer writes Claude Code hooks, agent instruction files, a Git pre-commit hook, a CI include file, and a package script. This is an unconsented lifecycle mutation of a foreign AI-agent control surface and project configuration. - **Rationale:** The package performs broad consumer-project and AI-agent control-surface writes during postinstall. The conditional checks do not establish user consent for those automatic changes. - **Files touched:** .claude/settings.json, AGENTS.md, CLAUDE.md, .githooks/pre-commit, .gitlab/suppa-schema-gate.yml, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook runs an installer against the consumer project., That installer adds command hooks to Claude Code settings., It also changes agent instruction files, Git hooks, CI configuration, and the consumer package manifest., These are unconsented install-time writes to a foreign project and AI-agent control surface. - **Evidence against:** The postinstall hook skips some environments and projects that do not look like Suppa applications., No lifecycle code path inspected sends harvested data or downloads a payload. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node skills/suppa-entity-code/scripts/postinstall.mjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node skills/suppa-entity-code/scripts/postinstall.mjs ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** dist/tools/entityCode.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L81: try { L82: const mod = await import(pathToFileURL(p).href); L83: return String(mod.BLOCKING_SUMMARY ?? "").trim() || "the house rules in SKILL.md"; ``` ### 6. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 7.

High: Entrypoint Foreign Package Code Overwrite - **Category:** Source - **Confidence:** 94.0% - **Path:** dist/version.js - **Public source:** [View source]() Manifest-reachable source overwrites another installed package with package-defined remote behavior. Public source snippet (untrusted): ```javascript Manifest-reachable source resolves another installed package, overwrites its runtime code, and injects package-defined remote behavior. dist/version.js: * node_modules holds; publishing a fix changes nothing until that client is import { mkdirSync, readFileSync, renameSync, writeFileSync } from "node:fs"; const REGISTRY_URL = `https://registry.npmjs.org/${PACKAGE_NAME}/latest`; writeFileSync(tmp, `${JSON.stringify(cache, null, 2)}\n`, "utf-8"); ``` ### 10. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 11.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 90.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, prepublishOnly - **Dependencies:** 3 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 3 - **Published dependency-graph edges:** 3 ### Published dependency entries - @modelcontextprotocol/sdk ^1.18.0 (Dependency) - @napi-rs/keyring ^1.1.0 (Dependency) - zod ^3.23.8 (Dependency) ## Package metadata - **Package:** suppa-mcp-2 - **Ecosystem:** npm - **Version:** 1.17.0 - **License:** MIT - **Version published:** 2026-08-28T09:08:10.930Z - **Package first seen:** 2026-07-01T09:59:52.851Z - **Package last seen:** 2026-08-28T11:18:21.957Z - **Known versions:** 13 - **Latest version:** 1.20.0 - **Appeal under review:** No - **Description:** MCP server for the Suppa platform (modern.suppa.me) — Tasks, Docs/Pages, Entities & Schema, Forms, Automations, and file attachments, with multi-tenant Google auth.
