// GLOSSARY -- POLICY ENFORCEMENT
What is Policy-as-Code (MCP)?
Expressing MCP tool access rules as version-controlled, machine-readable configuration (typically YAML) rather than UI-configured settings, enabling audit trails, peer review, and CI/CD integration.
WHY IT MATTERS
UI-based policy management doesn't scale. When you have 50 agents accessing 200 tools, clicking through permission dialogs isn't viable. Policy-as-code treats access rules like any other configuration — stored in git, reviewed in PRs, deployed through CI/CD.
This brings software engineering rigour to agent governance. Every policy change has an author, a timestamp, a review, and a rollback path.
HOW POLICYLAYER USES THIS
Intercept policies are YAML files. They live in your repo, go through code review, and deploy alongside your application. No dashboard clicking required.
