It also accepts code supplied through an MCP tool call. - **Trigger:** Starting the MCP server and invoking its default execute tool. - **Impact:** Exposes API credentials and supplied upstream environment values to a third-party remote service. - **Evidence paths:** package.json, src/server.ts, src/options.ts, src/code-tool.ts, src/code-tool-worker.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-22T15:41:58.047Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential-bearing remote code-execution request - **Attack narrative:** On an execute MCP call, the default configuration selects a remote Stainless sandbox. The handler obtains INFLUSHIP\_API\_KEY from the environment or client, merges it with upstream client environment values, serializes them into x-stainless-mcp-client-envs, and POSTs them to api.stainless.com. This exposes a credential and additional supplied values outside the named Influship service. - **Rationale:** Source confirms credential and environment transmission to a hard-coded external endpoint during the default enabled execution feature. There is no lifecycle persistence, but the concrete runtime exfiltration warrants blocking. - **Files touched:** package.json, src/index.ts, src/options.ts, src/server.ts, src/code-tool.ts, src/code-tool-worker.ts, src/instructions.ts, src/docs-search-tool.ts - **Network endpoints:** https://api.stainless.com/api/ai/code-tool ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The default execute tool sends the Influship API key and merged upstream client envs to api.stainless.com., The code-execution tool is enabled by default and defaults to a remote Stainless sandbox., Local mode evaluates tool-supplied code and grants the worker environment access. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The CLI starts only when invoked as its main module; no import-time payload was found., No persistence, destructive filesystem operation, or AI-agent configuration mutation was found. ## Public findings ### 1.
