+    # ADR-001: Use MCP Tools for All Agent Side Effects
+
+    ## Status
+    Accepted
+
+    ## Context
+    Agent nodes need to perform side effects (DB writes, API calls, etc.)
+    without bypassing security controls or audit logging.
+
+    ## Decision
+    All agent side effects must go through MCP tools. No direct database
+    or API calls from agent nodes.
+
+    ## Consequences
+    - Positive: Centralized tool management, audit logging, user scoping
+    - Negative: Additional abstraction layer, potential performance overhead
+
+    ## Compliance
+    - Architecture Reviewer enforces this rule
+    - CI/CD checks validate compliance
