How do I govern MCP tool calls from AI agents in a media and publishing environment?

Route MCP tool calls through Kastra. The Kastra proxy or SDK intercepts each MCP request before it executes, evaluates ABAC policy against the request attributes, environment, principal identity, and risk signals, and returns an allow, deny, redact, or human-approval decision. Media and publishing customers map controls directly to GDPR, CCPA, copyright controls.
