Designing Zero-Trust Multi-Agent Workflows with Model Context Protocol (MCP)

An architectural reference guide for securing tool endpoints, token verification, role-based tool scope restrictions, and sandboxing MCP servers in enterprise agent networks.

Key Takeaways

  • Model Context Protocol (MCP) establishes a standardized transport layer for LLM tool integration, but requires explicit security boundaries.
  • Implementing OAuth 2.0 bearer token validation at the MCP server level prevents unauthorized agent action escalation.
  • Role-Based Tool Scoping restricts worker sub-agents from executing high-privilege administrative functions.
