Plaintext credential storage and lack of sandboxing in MCP tools

9/10 Critical

Many MCP tools run with full host access (launched via npx or uvx) with no isolation or sandboxing. Credentials are commonly passed as plaintext environment variables, exposing sensitive data. Tools lack enterprise-ready features like policy enforcement and audit logs.
