server configuration within an mcpServers object, matching the
expected format for MCP config files.

 ## Advanced Configuration
 
+### Custom Environment Variables
+
+You can pass custom environment variables to Claude Code execution using the `claude_env` input. This is useful for CI/test setups that require specific environment variables:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    claude_env: |
+      NODE_ENV: test
+      CI: true
+      DATABASE_URL: postgres://test:test@localhost:5432/test_db
+    # ... other inputs
+```
+
+The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.

 ### Custom Tools
