+## Integration Catalog Commands
+
+### stella config integrations
+
+Manage the live Integration Catalog through the Integrations service.
+
+**Usage:**
+```bash
+stella config integrations <command> [options]
+```
+
+**Subcommands:**
+- `list` - List catalog entries with filtering and paging
+- `providers` - List supported providers and discovery metadata
+- `get` / `show` - Display a single integration
+- `create` - Create an integration entry
+- `update` - Update an integration entry
+- `delete` / `remove` - Delete an integration entry
+- `test` - Run connector connectivity test
+- `health` - Query connector health
+- `impact` - Show workflow impact summary
+- `discover` - Discover provider resources such as repositories, projects, jobs, pipelines, or tags
+
+**Examples:**
+```bash
+# Show live providers (default hides test-only providers)
+stella config integrations providers
+
+# Include test-only providers such as InMemory
+stella config integrations providers --include-test-only --format json
+
+# Create a GitLab server entry
+stella config integrations create \
+  --name local-gitlab \
+  --type scm \
+  --provider gitlabserver \
+  --endpoint http://gitlab.stella-ops.local:8929 \
+  --authref authref://vault/gitlab#access-token
+
+# Discover projects from an existing integration
+stella config integrations discover <integration-id> --resource-type projects
+
+# Discover tags within a repository
+stella config integrations discover <integration-id> \
+  --resource-type tags \
+  --filter repository=team/api \
+  --filter namePattern='v*'
+
+# Register local MinIO through the object-storage provider
+stella config integrations create \
+  --name local-minio \
+  --type objectstorage \
+  --provider s3compatible \
+  --endpoint http://minio.stella-ops.local:9000
+```
+
+**Notes:**
+- `providers` returns `isTestOnly`, `supportsDiscovery`, and `supportedResourceTypes`.
+- Deprecated `stella integrations *` routes are preserved as aliases and forward to `stella config integrations *`.
+- Unsupported discovery requests return a client error instead of silently falling back to sample data.
