Installed AI clients can launch the package and receive persistent instructions favoring its tools. - **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:** 2.2.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Install-time code modifies multiple third-party AI-client control surfaces and instruction files. It registers the package as an MCP server and injects persistent agent instructions without a user setup action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-04T03:09:17.249Z - **Finished:** 2026-08-04T03:09:43.737Z - **Download time:** 753 ms - **Static scan time:** 2025 ms - **AI review time:** 23708 ms - **Total time:** 26488 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code modifies multiple third-party AI-client control surfaces and instruction files. It registers the package as an MCP server and injects persistent agent instructions without a user setup action. - **Trigger:** npm postinstall - **Impact:** Installed AI clients can launch the package and receive persistent instructions favoring its tools. - **Evidence paths:** package.json, scripts/postinstall.mjs, build/index.js, build/commands/setup.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T03:09:43.737Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic multi-client MCP registration and AI instruction-file injection - **Attack narrative:** On installation, the postinstall script launches the package's setup command. Setup discovers installed AI clients, writes an aidex MCP entry into their configuration, invokes Claude's MCP CLI, and appends or replaces marked instruction blocks in Claude/Gemini instruction files. The injected text directs agents to prefer AiDex and automatically initialize it, creating an unconsented cross-client agent-control-surface change. - **Rationale:** This is concrete unconsented postinstall mutation of foreign, broad AI-agent control surfaces. It meets the firewall block policy even though no separate exfiltration chain was found. - **Files touched:** scripts/postinstall.mjs, build/index.js, build/commands/setup.js, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.gemini/settings.json, ~/.gemini/GEMINI.md, ~/.claude/CLAUDE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/postinstall.mjs invokes build/index.js setup., build/commands/setup.js registers with Claude, Cursor, Windsurf, Gemini, and VS Code configs., setup.js writes coercive AiDex instructions to CLAUDE.md and GEMINI.md., Registration occurs without an explicit user setup command. - **Evidence against:** Postinstall honors CI and AIDEX\_NO\_SETUP=1., Client JSON writes are guarded by detected client directories., No covert remote payload download or credential exfiltration found in inspected paths. ## 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 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 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: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 6. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 7. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 8. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 9. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 10. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% 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:** 21 - **Optional dependencies:** 2 - **Peer dependencies:** 0 - **Development dependencies:** 9 - **Published dependency-graph edges:** 23 ### Published dependency entries - @modelcontextprotocol/sdk ^1.0.0 (Dependency) - @tree-sitter-grammars/tree-sitter-hcl ^1.2.0 (Dependency) - better-sqlite3 ^12.0.0 (Dependency) - chokidar ^5.0.0 (Dependency) - express ^4.22.1 (Dependency) - glob ^10.0.0 (Dependency) - highlight.js ^11.11.0 (Dependency) - minimatch ^10.1.1 (Dependency) - simple-git ^3.27.0 (Dependency) - tree-sitter ^0.25.0 (Dependency) - tree-sitter-c ^0.24.1 (Dependency) - tree-sitter-c-sharp 0.23.1 (Dependency) - tree-sitter-cpp ^0.23.4 (Dependency) - tree-sitter-go ^0.25.0 (Dependency) - tree-sitter-java ^0.23.5 (Dependency) - tree-sitter-php ^0.24.2 (Dependency) - tree-sitter-python ^0.25.0 (Dependency) - tree-sitter-ruby ^0.23.1 (Dependency) - tree-sitter-rust ^0.24.0 (Dependency) - tree-sitter-typescript ^0.23.2 (Dependency) - ws ^8.19.0 (Dependency) - @xenova/transformers ^2.17.2 (OptionalDependency) - sqlite-vec ^0.1.9 (OptionalDependency) ## Package metadata - **Package:** aidex-mcp - **Ecosystem:** npm - **Version:** 2.2.2 - **License:** MIT - **Version published:** 2026-06-30T16:37:07.393Z - **Package first seen:** 2026-08-04T03:09:43.737Z - **Package last seen:** 2026-08-09T16:55:57.843Z - **Known versions:** 2 - **Latest version:** 2.3.0 - **Appeal under review:** No - **Description:** MCP Server for persistent code indexing.
