On a later editor launch, those clients can start the package through npx; its server reads the project .env DATABASE\_URL. - **Trigger:** npm installation followed by opening the project in a supported editor - **Impact:** Adds an AI-agent tool and automatic execution path to foreign project/editor control surfaces, with access to the configured database connection. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/index.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-15T23:47:44.852Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented install-time editor MCP configuration injection - **Attack narrative:** Installing the package invokes postinstall. The hook walks out of node\_modules to the consumer project and creates missing MCP configuration for multiple editors, registering an npx pgautopilot command. This is an unconsented mutation of broad, foreign AI-agent control surfaces. When an editor subsequently loads the project, it can launch the MCP server, which reads the project working directory’s .env DATABASE\_URL and exposes database-management tools to the editor’s AI client. - **Rationale:** The postinstall hook concretely injects MCP launch configuration into multiple third-party editor directories under the consumer project. This meets the install-time foreign/broad AI-agent control-surface block policy even without separate exfiltration code. - **Files touched:** .cursor/mcp.json, .vscode/mcp.json, .codeium/windsurf/mcp\_config.json, .env.example, .env ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs automatically on npm installation., The hook locates the consuming project root rather than staying in its package directory., It creates Cursor, VS Code, and Windsurf MCP configuration files that launch pgautopilot via npx., The generated MCP server reads the project working directory’s .env, including DATABASE\_URL. - **Evidence against:** Existing editor config files are left untouched., No source evidence of HTTP exfiltration, remote payload download, or credential transmission was found. ## Public findings ### 1.
