v2.0.0

Release Notes — MCP Integration & Advanced AI Capabilities

Version: v2.0.0
Date: 2025-08-22

Highlights

• MCP Server Integration: Connect to external Model Context Protocol servers with STDIO, HTTP, and SSE transport support for expanded AI capabilities.
• Advanced Context Management: Intelligent conversation summarization, persistent memory system, and automatic planning with token-aware context compression.
• Enhanced AI Tools: Similarity search, document link traversal, Obsidian base file support, and comprehensive document analysis capabilities.
• Multi-Modal AI Architecture: Specialized Chat, Compose, and Write modes with reasoning display, placeholder states, and modular instruction system.
• Architectural Overhaul: Complete code reorganization with focused services, enhanced path utilities, and improved error handling.

Changes

• Added:

  • MCPManager.ts for handling multiple MCP server connections with OAuth flow detection and retry logic.
  • ContextManager.ts, SummarizerService.ts, MemoryService.ts, and PlanningService.ts for intelligent context management.
  • Enhanced AI instruction system with modular prompts in src/instructions/ directory structure.
  • Comprehensive tool suite: similarity search, link traversal, base file operations, and planning tools.
  • PathUtils.ts for centralized path handling with team-docs vs vault-wide scope support.
  • MCP server configuration UI in settings with transport type selection and connection monitoring.
  • Context management settings for AI scope, summarization, and retrieval parameters.
  • OAuth authentication handling via OAuthManager.ts for MCP servers requiring authentication.
  • Token estimation and context policies for smart conversation management.

• Changed:

  • Reorganized UI components into components/ and modals/ folders with focused responsibilities.
  • Split AI tools into modular architecture: core/, obsidian/, navigation/ tool categories.
  • Enhanced chat interface with MCP server selection, reasoning display, and improved message rendering.
  • Updated file reservation system to use relative paths and improved Git commit parsing.
  • Enhanced settings structure with new sections for MCP configuration and context management.
  • Improved activity feed with better path handling and cleaner display of reservation events.
  • Added GPG signing fallback in Git operations and better error handling throughout.
  • Enhanced provider selection with model-specific last-used settings and improved UI responsiveness.

• Fixed:

  • GPG signing issues in Git operations with automatic fallback to --no-gpg-sign.
  • Path resolution improvements for cross-platform compatibility and team collaboration.
  • Better OAuth flow handling and permission error detection for MCP servers.
  • Enhanced error messages and recovery mechanisms throughout the application.

Dependencies

• Added @modelcontextprotocol/sdk ^1.17.3 for MCP server integration.
• Updated various AI SDK dependencies for improved provider support and compatibility.

Tests

• Updated test structures to accommodate new architectural patterns.
• Enhanced mock utilities for testing new services and components.
• Maintained backward compatibility for existing test suites.

Notes

• MCP integration allows AI to access external tools and data sources beyond your documentation.
• Context management automatically handles conversation length and memory extraction.
• The modular instruction system enables provider-specific optimizations and better tool coordination.
• Path utilities support both team-docs scoped and vault-wide AI operations.

Potential follow-ups

• Add comprehensive MCP server examples and configuration guides.
• Implement visual MCP tool execution feedback in the chat interface.
• Enhance similarity search with semantic embedding support.
• Add collaborative planning features with shared scratchpads.
• Implement advanced memory querying and fact verification.
