The installed MCP process can then read the user's Warp API configuration and make authenticated Warp API calls. - **Trigger:** npm installation executes postinstall; restarting Claude Desktop activates the injected MCP entry. - **Impact:** Unconsented persistence in a foreign AI-agent control surface, causing Claude Desktop to launch the package with user privileges. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/run.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T21:55:53.273Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time creation or replacement of a Claude Desktop MCP server entry - **Attack narrative:** On installation, the package's postinstall script locates or creates Claude Desktop's configuration file and writes an MCP server entry named warp. That entry runs the package launcher whenever Claude Desktop starts. The launcher starts the bundled MCP server, which reads the user's Warp configuration and is configured to access Warp's API. This is an unconsented install-time mutation of a foreign AI-agent control surface. - **Rationale:** The automatic postinstall writes a persistent Claude Desktop MCP command without user invocation or consent. This meets the install-control-surface blocking criterion regardless of the package-aligned API functionality. - **Files touched:** scripts/postinstall.mjs, scripts/run.mjs, ~/Library/Application Support/Claude/claude\_desktop\_config.json, ~/AppData/Roaming/Claude/claude\_desktop\_config.json, ~/.config/Claude/claude\_desktop\_config.json, ~/.warp/config.json - **Network endpoints:** https://www.wearewarp.com/api/v1/warp ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs automatically on npm installation., It selects a Claude Desktop configuration path under the user home directory., It creates or overwrites config.mcpServers.warp with a command to execute this package's launcher., The launcher starts the MCP server with access to the user's Warp config and API endpoint. - **Evidence against:** No remote code download or shell payload execution was found in the inspected lifecycle script., The runtime API calls target declared Warp endpoints, but this does not mitigate the unconsented install-time Claude mutation. ## Public findings ### 1.
