Remove URL rewriting logic from MCP server that was converting
public URLs to internal Docker URLs. This was a workaround for
Nextcloud's overwritehost setting forcing URLs to localhost:8080.
Changes:
- Remove OIDC endpoint rewriting in app.py (setup_oauth_config)
- Remove OIDC_JWKS_URI override support (no longer needed)
- Remove URL rewriting in browser_oauth_routes.py
- Remove URL rewriting in token_broker.py
- Update Helm chart values and README
- Add hybrid auth setup unit tests
- Update Astrolabe admin UI for Vue 3
The proper fix is in the previous commit which removes the
overwritehost setting from Nextcloud, allowing it to respect
the Host header from incoming requests.
Critical fix:
- deployment.yaml: Only reference OAuth credentials when clientId is set
- Fixes pod failure when using existingSecret without static OAuth creds
- Aligns deployment behavior with secret template logic
Previously, the deployment referenced OAuth credentials when either
clientId OR existingSecret was set. However, the secret template only
includes OAuth credentials when clientId is explicitly provided. This
caused pod failures when users provided an existingSecret for offline
access without static OAuth credentials (intending to use DCR).
The fix ensures OAuth env vars are only referenced when clientId is set,
matching the OAuth mode pattern and allowing DCR to work correctly with
existingSecret configurations.
Minor improvements:
- values.yaml: Clarify OAuth credentials are optional (uses DCR if not provided)
Testing verified all scenarios:
✅ Pass-through only (no offline access): No secrets/PVCs/OAuth vars
✅ Offline + DCR (no clientId): Secret with encryption key only, no OAuth vars
✅ Offline + static OAuth: Secret with all keys, OAuth vars present
✅ existingSecret without clientId: No auto secret, no OAuth vars (FIXED)
Resolves reviewer feedback from PR #447
Fixes Kubernetes label validation error when deploying dashboard ConfigMap.
Problem:
- Kubernetes labels cannot contain spaces (validation regex: [A-Za-z0-9][-A-Za-z0-9_.]*[A-Za-z0-9])
- Previous implementation had grafana_folder: "Nextcloud MCP" as a label
- Deployment failed with: "Invalid value: 'Nextcloud MCP'"
Solution:
- Move grafana_folder from labels to annotations (annotations allow spaces)
- Keep grafana_dashboard="1" as label for ConfigMap discovery
- Grafana sidecar reads folder name from folderAnnotation parameter
Changes:
- dashboard-configmap.yaml: Move grafana_folder to annotations section
- dashboards/README.md: Fix kubectl commands to use annotations
- values.yaml: Update comments to clarify annotation usage
This follows the standard kube-prometheus-stack pattern where:
- Labels are used for ConfigMap discovery (strict validation)
- Annotations are used for metadata like folder names (relaxed validation)

Add support for configurable document chunking parameters to Helm chart
to match docker-compose and application capabilities.
Changes:
1. values.yaml:
- Add documentChunking section with chunkSize (512) and chunkOverlap (50)
- Include comprehensive comments explaining chunking strategies
- Positioned between vectorSync and qdrant sections
2. templates/deployment.yaml:
- Add DOCUMENT_CHUNK_SIZE and DOCUMENT_CHUNK_OVERLAP env vars
- Always set (not conditional), used by vector sync processor
- Environment variables follow same pattern as config.py defaults
3. README.md:
- Add documentChunking parameter table in Vector Search section
- Document chunking strategies (small/medium/large chunks)
- Explain overlap recommendations (10-20% of chunk size)
Validation:
- helm lint: Passes
- helm template: Environment variables correctly generated
- Custom values: Work as expected (tested with chunkSize=1024)
- Always present: Not conditional on vectorSync.enabled
This maintains feature parity between Helm and docker-compose deployments,
allowing users to tune chunking for their embedding models and use cases.

Add support for three Qdrant deployment modes in Helm chart:
1. In-memory mode (:memory:) - Default, zero-config, ephemeral storage
2. Persistent local mode (path-based) - File-based storage with PVC
3. Network mode (URL-based) - Dedicated Qdrant service or external instance
Changes:
- Restructured qdrant configuration in values.yaml with mode selector
- Added conditional environment variable logic in deployment.yaml
- Created PVC template for persistent local mode with optional existingClaim
- Added qdrantPvcName helper template in _helpers.tpl
- Updated README.md with Helm registry URL (https://cbcoutinho.github.io/nextcloud-mcp-server)
Breaking change: Default changed from requiring qdrant.enabled to using
in-memory mode (:memory:) when no Qdrant configuration is provided.

Add support for deploying Qdrant vector database and Ollama embedding
service as optional helm chart dependencies. Enables semantic search
capabilities for Nextcloud content with flexible deployment options.
Chart Dependencies:
- Add Qdrant v0.9.0 from qdrant/qdrant-helm (conditional)
- Add Ollama v1.33.0 from otwld/ollama-helm (conditional)
- Both dependencies only deploy when enabled
Configuration (values.yaml):
- vectorSync: Background sync settings (interval, workers, queue size)
- qdrant: Subchart config with persistence, resources, clustering
- ollama: Subchart config with model pull, persistence, resources
- Support for external Ollama via ollama.url (no subchart deployment)
- openai: Alternative embedding provider (OpenAI or compatible API)
Environment Variables (deployment.yaml):
- VECTOR_SYNC_* variables when vectorSync.enabled
- QDRANT_URL, QDRANT_COLLECTION when qdrant.enabled
- OLLAMA_BASE_URL, OLLAMA_EMBEDDING_MODEL when ollama enabled or URL set
- OPENAI_API_KEY when openai.enabled
Documentation:
- README: New "Vector Search & Semantic Capabilities" section
- README: Example 5 showing three deployment patterns
- NOTES.txt: Conditional guidance when vector features enabled
- Secret template for OpenAI API key management
All features disabled by default for backward compatibility.
Tested with helm template and helm lint.
