## Future Roadmap

See [ROADMAP.md](ROADMAP.md) for detailed implementation plans.

### Phase 1: Foundation (P0-P1)
- **Path Normalization** - Consistent path handling across platforms
- **Error Message Improvements** - Clear, actionable error messages with troubleshooting tips
- **Enhanced Authentication** - Secure API key management, multiple keys with labels, expiration, rate limiting, audit logging, and permission scopes
- **API Unification** - Standardize parameter naming and return structured, typed results
- **Discovery Endpoints** - Add `stat` and `exists` tools for exploring vault structure

### Phase 2: Enhanced Operations (P1-P2)
- **Write Operations & Concurrency** - ETag-based version control, partial updates (frontmatter, sections)
- **Conflict Resolution** - Create notes with conflict strategies (error, overwrite, rename)
- **File Rename/Move** - Rename or move files with automatic wikilink updates
- **Enhanced List Operations** - Filtering, recursion control, pagination, frontmatter summaries
- **Advanced Search** - Regex search, snippet extraction, glob filtering

### Phase 3: Advanced Features (P2-P3)
- **Frontmatter Parsing** - Read and update frontmatter without modifying content
- **Linking & Backlinks** - Wikilink validation, resolution, and backlink queries
- **Waypoint Support** - Tools for working with Waypoint plugin markers
- **Excalidraw Support** - Specialized tool for reading Excalidraw drawings

### Future Considerations
- **Resources API** - Expose notes as MCP resources
- **Prompts API** - Templated prompts for common operations
- **Batch Operations** - Multiple operations in single request
- **WebSocket Transport** - Real-time updates and notifications
- **Graph API** - Enhanced graph visualization and traversal
- **Tag & Canvas APIs** - Query tags and manipulate canvas files
- **Dataview Integration** - Query vault using Dataview syntax
