mcp-server-cloudflare

The repository is a monorepo containing multiple distinct MCP servers, each leveraging Cloudflare services. Authentication is handled via Cloudflare OAuth or API tokens, with granular scopes defined per server to limit access. Sensitive credentials like `MCP_COOKIE_ENCRYPTION_KEY`, `CLOUDFLARE_CLIENT_ID`, and `CLOUDFLARE_CLIENT_SECRET` are expected to be provided via environment variables, not hardcoded. Logging and error tracking (via Sentry and Analytics Engine) are integrated for observability. A significant security consideration is the `apps/sandbox-container` server, which is explicitly designed to allow arbitrary code execution (`exec`) and file system operations within its environment. While this is its intended function as a sandbox, it introduces an inherent risk if not deployed and managed with robust isolation (e.g., secure containerization) and strict access controls. An LLM interacting with this tool could potentially be prompted to perform harmful actions within the sandboxed environment. The documentation indicates per-user Durable Object instances for containers and a user blocklist mechanism, which improves isolation and access control. However, the presence of direct `child_process.exec` calls in a server component requires careful consideration of the execution environment's isolation from the host system.
