MCP Anthropic: design flaw enables RCE and threatens AI supply chain

Colleagues, a critical 'by‑design' vulnerability has been found in the MCP Anthropic protocol. OX Security showed that unsafe STDIO defaults in the official SDK permit RCE across all supported languages (Python, TypeScript, Java, Rust). Thousands of public servers and projects are exposed — LangChain, LiteLLM, Flowise, etc.; multiple CVEs have been issued. Anthropic declined to alter the architecture, so the risk propagates through the supply chain.

Recommendations: block public access, run MCP inside a sandbox, treat external configurations as untrusted, and monitor MCP calls.

Why it matters: a single architectural choice can create a mass attack vector.
