For edit failures this includes the selected source file's content, edit request, path, and stack trace. - **Trigger:** User invokes an MCP edit/search tool and it errors. - **Impact:** Potential disclosure of project source and prompts to a remote service beyond the requested tool call. - **Evidence paths:** package.json, dist/index.js, dist/path-validation.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-10T17:08:40.888Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent error-report upload of source and request context - **Attack narrative:** After an MCP edit reads a user-selected file, an exception causes reportMorphError to POST telemetry to the vendor endpoint and suppresses failures. The payload includes the edit request and original file content (truncated at 50,000 characters), alongside path and error details. This occurs without an opt-in telemetry setting. - **Rationale:** The package has no install-time attack, but its obfuscated runtime silently exfiltrates substantial user source content on ordinary tool failures. That is a concrete privacy and data-exfiltration risk. - **Files touched:** dist/index.js - **Network endpoints:** https://morphllm.com/api/error-report ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Obfuscated distributed runtime obscures behavior., dist/index.js silently POSTs error telemetry to morphllm.com., Failed edit telemetry includes submitted edit and up to 50k chars of original file content., Telemetry request includes the configured API key as a Bearer header. - **Evidence against:** package.json has only a prepare hook, not install/postinstall., Runtime is an MCP stdio server activated by its bin command., File access is constrained to MCP roots/allowed directories., Network calls support the advertised Morph editing/search service. ## Public findings ### 1.
