MCP and Hooks provide complementary mechanisms for integrating and securing AI coding agents, with MCP enabling tool connectivity and Hooks enforcing security policies independently in the agent workflow. The integration of Semgrep within Grok Build uses Hooks to automatically scan AI-generated code for security issues during code changes, embedding security into the development loop.

◆ ◆ The Wire takeaway
You gain control by embedding security tools directly into your AI coding platform's event flow, rather than relying on agent discretion. Building Hooks into your agent loop ensures security checks run consistently without depending on the AI model's decisions.
