ClickUp MCP Server

# Finalize CLAUDE.md ## Epic: Finalize CLAUDE.md Complete the remote MCP server architecture documentation in CLAUDE.md, establishing it as the single source of truth for all other documentation. **Estimated Duration**: 3h **Phase**: 1 **Priority**: critical **Complexity**: Standard ## Methodology Guidance This task follows the **Distributed SPECTRA** methodology for autonomous agent execution. **Your Focus**: Context → Clarify (if needed) → Implement → Test → Refine → Handoff **Time Allocation Guide**: - Context Gathering (5-10%): Review current CLAUDE.md, documentation standards, actual implementation code - Implementation (40-50%): Complete all architecture sections with accurate technical details - Testing (25-30%): Validate against actual implementation, test all examples - Refinement (5-10%): Ensure clarity, consistency, completeness - Handoff (5-10%): Document architecture decisions for README.md task **Wave Context**: Wave 2 (Core Architecture) - Depends on Phase 0.2 Review handoffs from: phase-0-2-documentation-standards.md (terminology, templates, standards) **Quality Requirements**: - ✅ Architecture descriptions must match actual implementation - ✅ Tool count must be exactly 72 across 12 categories - ✅ OAuth/JWT flow must be technically accurate - ✅ All code examples must be tested - ✅ Handoff required - README.md depends on this architecture 📚 **Full Methodology**: `~/.claude/docs/agent-task-execution-methodology.md` ## Context **Why this matters**: CLAUDE.md is the technical foundation document that all other docs reference. If this is wrong, everything else will be wrong. It serves as the single source of truth for architecture, tool counts, and authentication model. **What it depends on**: - Phase 0.2 (documentation standards and terminology) - Actual implementation code in `src/` (for accuracy) **What depends on it**: - Phase 1.2 (README.md rewrite) - Phase 2.1 (OAuth documentation) - Phase 2.4 (Tool reference) - Phase 2.5 (API reference) ## Tasks - [ ] Review current CLAUDE.md and git diff (30m) - Agent: Technical Writer - Read existing CLAUDE.md - Review uncommitted changes - Identify what's complete vs what needs work - Note any inaccuracies - [ ] Update Repository Overview section (30m) - Agent: Technical Writer - Change description to "Remote MCP Server hosted on CloudFlare Workers" - Update tool count from 36+ to 72 tools across 12 categories - Add OAuth authentication mention in overview - Reference test-all-tools-ultrathink.js for tool validation - [ ] Complete Architecture - Remote MCP Server section (60m) - Agent: Backend Specialist - Document CloudFlare Workers SaaS architecture - Add service layer pattern (Worker, OAuth, User Management, Security, Transport) - Create Mermaid diagram of architecture - Document OAuth 2.0 + PKCE flow - Explain JWT session management - Detail multi-tenant user isolation - [ ] Update Development Commands section (20m) - Agent: DevOps Specialist - Add CloudFlare Workers commands (build:worker, dev:worker, deploy) - Keep traditional MCP commands for reference - Add testing commands including test-all-tools-ultrathink.js - Document environment variables for Workers vs traditional mode - [ ] Add/update environment variables section (20m) - Agent: DevOps Specialist - Document CloudFlare Workers environment (ENCRYPTION_KEY, JWT_SECRET, etc.) - Document traditional mode environment (CLICKUP_API_KEY, CLICKUP_TEAM_ID) - Explain when to use which mode - Add security notes for sensitive values - [ ] Validate all content against implementation (20m) - Agent: QA Specialist - Check src/worker.ts for architecture accuracy - Verify src/auth/oauth-service.ts for OAuth details - Confirm tool count with test-all-tools-ultrathink.js - Test any code examples - Cross-reference with actual environment variables ## Acceptance Criteria - [ ] Repository Overview accurately describes remote SaaS architecture - [ ] Tool count is exactly 72 tools across 12 categories - [ ] Architecture section includes CloudFlare Workers service layer diagram - [ ] OAuth 2.0 + PKCE flow documented with technical accuracy - [ ] JWT session management explained - [ ] Development commands include both Workers and traditional modes - [ ] Environment variables documented for both modes - [ ] All technical details verified against actual implementation code - [ ] No mentions of "local NPX installation" or "STDIO only" - [ ] Document serves as single source of truth for architecture - [ ] Handoff created documenting architecture for README.md task ## Dependencies - Depends on: Phase 0.2 (documentation standards - terminology, templates) - Blocks: Phase 1.2 (README.md rewrite needs this architecture) - Blocks: Phase 2.1 (OAuth docs need architecture reference) - Blocks: Phase 2.4 (Tool reference needs tool count) - Blocks: Phase 2.5 (API reference needs architecture) ## Technical Notes **Key Architecture Elements to Document**: 1. CloudFlare Workers SaaS platform 2. OAuth 2.0 + PKCE authentication flow 3. JWT session tokens (24-hour lifetime, refresh capability) 4. Multi-tenant user isolation 5. AES-256-GCM encryption for stored API keys 6. Rate limiting (100/min free, 500/min premium) 7. Audit logging to R2 8. HTTP Streamable transport for remote MCP **Service Layer Components** (from src/): - `worker.ts` - Hono-based HTTP handler with OAuth endpoints - `auth/oauth-service.ts` - ClickUp OAuth 2.0 + PKCE implementation - `services/user-service.ts` - Multi-tenant user management - `security/encryption.ts` - AES-256-GCM encryption - `security/audit.ts` - Audit logging - `middleware/rate-limit.ts` - Rate limiting - `mcp-worker-server.ts` - MCP protocol handler for Workers **Tool Categories** (from test-all-tools-ultrathink.js): - Task Management: 27 tools - List Management: 8 tools - Space Management: 6 tools - Custom Fields: 6 tools - Project Management: 5 tools - Document Management: 5 tools - Time Tracking: 5 tools - Folder Management: 4 tools - Workspace: 3 tools - Tag Management: 1 tool - Member Management: 1 tool - Other: 1 tool **Risks**: - Inaccurate technical details → Mitigation: Verify against source code - Inconsistent terminology → Mitigation: Use standards from Phase 0.2 - Incomplete architecture description → Mitigation: Cover all service layers ## Resources - [Current CLAUDE.md](CLAUDE.md) (review uncommitted changes) - [Architecture Code](src/worker.ts, src/auth/, src/security/) - [Test Script](test-all-tools-ultrathink.js) (for tool count validation) - [Documentation Standards](.claude/docs/documentation-checklist.md) - [PROJECT-DOCUMENTATION.md](~/.claude/docs/best-practices/PROJECT-DOCUMENTATION.md)
