WriteGuard: Fine-grained controls for MCP Servers
Aug 5, 2026Scott Roe-Meschke, Kenny Johnson

Summary
Introduced WriteGuard, a system for fine-grained control over AI agent actions on MCP servers. WriteGuard implements a shared policy, attribution, and auditing layer that sits between MCP clients and servers. It allows for defining risk tiers for tools, enabling/disabling them, and configuring labeling for agent attribution. WriteGuard also generates scrubbed audit events for agent activity, providing a centralized view of machine-speed actions across MCP-enabled systems.
