Claude Code Connector MCP

# Implementation Roadmap ## Overview Phased implementation plan for Claude Code Connector MCP, targeting 4 weeks total development time. --- ## Phase 1: MVP - Core File Operations (Week 1) ### Goal Enable basic project registration and file read/write operations from Claude Desktop. ### Features - ✅ Project registration and configuration management - ✅ File write from Desktop to project - ✅ File read from project to Desktop - ✅ Project listing - ✅ Basic slash commands ### Deliverables **Tools**: 1. `register_project` - Full implementation with validation 2. `list_projects` - With active/inactive filtering 3. `write_to_project` - With overwrite protection 4. `read_from_project` - With line range support **Slash Commands**: - `/projects` - List all registered projects - `/project {id}` - Set active project context - `/save {path}` - Quick save to active project **Configuration**: - `~/.claude/projects.json` schema and management - Config validation and error handling **Testing**: - Unit tests for all tools (>80% coverage) - Integration tests for file operations - Error handling tests ### Success Criteria - Developer can register a project - Developer can write spec from Desktop to project docs/ - Developer can read project files into Desktop - All slash commands work reliably - Tests pass ### Time Estimate: 5 days --- ## Phase 2: Claude Code Integration (Week 2) ### Goal Enable invocation of Claude Code CLI from Desktop with streaming status updates. ### Features - ✅ Claude Code process spawning - ✅ Streaming status updates - ✅ Task result parsing - ✅ Error handling and timeouts ### Deliverables **Tools**: 5. `invoke_claude_code` - Full implementation with streaming **Slash Commands**: - `/implement {task}` - Invoke Claude Code with task **CLI Integration**: - Process spawning with proper shell handling - Stdout/stderr capture and parsing - Streaming protocol implementation - Graceful timeout and termination - Result aggregation (files created/modified) **Testing**: - Unit tests for CLI invocation - Integration tests with mock Claude Code - Timeout and error handling tests - Streaming protocol tests ### Success Criteria - Developer can invoke Claude Code from Desktop - Status updates stream back in real-time - Results show files modified/created - Timeout handling works correctly - Error messages are clear ### Time Estimate: 5 days --- ## Phase 3: State Management (Week 3) ### Goal Implement checkpoint system for cross-interface state sharing. ### Features - ✅ Session state persistence - ✅ Checkpoint creation - ✅ Project status querying - ✅ Cross-interface context ### Deliverables **Tools**: 6. `create_checkpoint` - Save conversation state 7. `get_project_status` - Query project state **Slash Commands**: - `/checkpoint {summary}` - Create checkpoint - `/status` - Show project status **State Management**: - `.claude/session_state.json` schema - Atomic writes (temp file + rename) - Checkpoint history management - Task history tracking **Testing**: - Unit tests for state management - Integration tests for checkpoint flow - Atomic write tests - State corruption recovery tests ### Success Criteria - Checkpoints save reliably - State persists across Desktop sessions - VS Code can read checkpoint state - No data loss on concurrent access - Task history is accurate ### Time Estimate: 5 days --- ## Phase 4: Advanced Features (Week 4) ### Goal Add MCP resources, prompts, git integration, and performance optimization. ### Features - ✅ MCP resources for project data - ✅ MCP prompts for workflows - ✅ Git status integration - ✅ Performance optimization ### Deliverables **MCP Resources**: - `claude-code://{projectId}/files` - File tree resource - `claude-code://{projectId}/session` - Session state resource - `claude-code://{projectId}/docs` - Docs aggregation resource **MCP Prompts**: - `plan-and-implement` - Full workflow guide - `save-to-project` - Quick save workflow - `continue-in-cli` - CLI handoff workflow - `project-status` - Status overview workflow **Git Integration**: - Git status in `get_project_status` - Branch detection - Uncommitted changes count **Performance**: - File tree indexing and caching - Lazy resource loading - Debounced tool calls - Large project optimization (100k files) **Testing**: - Resource tests - Prompt tests - Performance benchmarks - Large project tests ### Success Criteria - Resources load in <100ms - Prompts guide users effectively - Git status shows accurately - Works with 100k file projects - All tools respond in <500ms ### Time Estimate: 5 days --- ## Post-Launch: Maintenance & Enhancement ### Monitoring - Usage telemetry (opt-in) - Error tracking - Performance metrics - User feedback collection ### Enhancement Backlog - [ ] Multi-project operations (work across multiple projects) - [ ] Remote project support (SSH, containers) - [ ] Webhook integration for external systems - [ ] Custom slash command registration - [ ] Project templates - [ ] Automated testing workflows - [ ] VS Code extension API - [ ] Claude Code task presets - [ ] Project search/filtering - [ ] Bulk operations ### Bug Fixes & Polish - Address user-reported issues - Performance tuning based on real usage - Error message improvements - Documentation updates --- ## Risk Mitigation ### Technical Risks **Risk**: Claude Code CLI API is different than assumed **Mitigation**: Early discovery in Phase 2, flexible adapter pattern **Impact**: Medium - May require API redesign **Risk**: File system race conditions **Mitigation**: Atomic writes, file locking, thorough testing **Impact**: Low - Well-understood problem **Risk**: Streaming protocol complexity **Mitigation**: Start simple (polling), iterate to SSE if needed **Impact**: Low - Can ship without streaming **Risk**: Large project performance **Mitigation**: Indexing, caching, lazy loading from day 1 **Impact**: Medium - Core requirement ### Schedule Risks **Risk**: Phase takes longer than estimated **Mitigation**: MVP-first approach, cut scope to ship Phase 1 **Impact**: Medium - Can deliver value incrementally **Risk**: Dependencies on external teams **Mitigation**: Mock external dependencies, minimal coupling **Impact**: Low - Self-contained project --- ## Launch Checklist ### Pre-Alpha (Internal Testing) - [ ] Phase 1 complete and tested - [ ] Documentation written - [ ] Internal dogfooding by PM (Brian) - [ ] Basic error handling in place ### Alpha (Limited Release) - [ ] Phases 1-2 complete - [ ] Integration tests passing -
