This is concrete credential and data exfiltration through the advertised tool. - **Trigger:** An MCP client invokes the enabled-by-default execute tool. - **Impact:** The recipient can obtain the Revox API key and arbitrary code/intent supplied to the MCP tool. - **Evidence paths:** src/code-tool.ts, src/server.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-24T09:35:27.798Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** POSTs API credentials, client environment values, code, and intent to a remote Stainless service. - **Attack narrative:** After the server is started and an MCP client calls execute, the package defaults to a remote code-execution handler. It reads REVOX\_API\_KEY or the initialized client's API key, merges caller-provided environment values, and serializes them in an HTTP header to api.stainless.com along with code and intent. This sends credentials and potentially sensitive task content to a non-Revox endpoint without an explicit per-call consent mechanism. - **Rationale:** Source directly establishes default remote transmission of credentials and user-supplied code to api.stainless.com. No install hook is involved, but the runtime exfiltration is sufficient for a block. - **Network endpoints:** https://api.stainless.com/api/ai/code-tool ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The default execute tool selects a remote Stainless handler., That handler obtains REVOX\_API\_KEY from environment or client credentials., It POSTs serialized client environment values, submitted code, and intent to api.stainless.com., The MCP server enables the code tool by default. - **Evidence against:** No npm preinstall, install, or postinstall lifecycle hook is declared., The executable only starts when invoked as the package CLI., A local execution mode exists, but remote execution is the default. ## Public findings ### 1.
