Notion MCP + Spatial Integration Plan

Executive Summary

This document outlines the implementation plan for integrating Notion with Piper Morgan using the MCP + Spatial Intelligence pattern. The integration will follow the established architectural patterns from GitHub and Slack integrations, providing a unified approach to external tool integration.

Authentication Strategy

OAuth vs Integration Token Approach

• Integration Token (Recommended): Simpler setup, no user consent flow required
• OAuth: More complex but provides user-specific access and better security
• Decision: Start with Integration Token for MVP, upgrade to OAuth for production

Required Notion Setup

1. Create Notion integration at https://www.notion.so/my-integrations
2. Generate internal integration token
3. Share specific databases/pages with the integration
4. Configure workspace permissions

PM-Relevant Data Structures

Core Notion Entities

• Databases: Product requirements, meeting notes, roadmap, task tracking
• Pages: Meeting notes, documentation, project updates
• Blocks: Text, code, images, tables, toggles
• Properties: Status, priority, assignee, due dates, tags

Key Use Cases

1. Product Requirements Management: Structured databases with status tracking
2. Meeting Documentation: Rich text pages with action items
3. Project Roadmap: Timeline databases with milestone tracking
4. Task Management: Kanban-style databases with workflow states

Spatial Dimensions for Notion

Based on the existing spatial patterns in the codebase, here’s how Notion entities map to the 8-dimensional spatial framework:

1. HIERARCHY (Page/Database Nesting)

• Territory: Notion workspace
• Room: Database or page collection
• Path: Page hierarchy (parent-child relationships)
• Object: Individual blocks or properties

2. TEMPORAL (Timestamps)

• Created: Page/database creation time
• Last Edited: Most recent modification
• Due Dates: Task deadlines and milestones
• Meeting Times: Scheduled event timestamps

3. PRIORITY (Status & Importance)

• Status Properties: Not started, in progress, complete
• Priority Levels: Low, medium, high, urgent
• Importance Tags: Critical, nice-to-have, optional

4. COLLABORATIVE (Authors & Editors)

• Created By: Original author
• Last Edited By: Most recent contributor
• Assigned To: Task ownership
• Reviewers: Approval workflow participants

5. CONTENT TYPE (Rich Media)

• Text Blocks: Plain text, rich text, code
• Media: Images, files, videos, embeds
• Structured Data: Tables, databases, forms
• Interactive Elements: Toggles, checkboxes, buttons

6. WORKFLOW STATE (Process Flow)

• Task States: Backlog, active, review, done
• Approval Flow: Draft, review, approved, published
• Development Stages: Planning, development, testing, deployment

7. RELATIONSHIP (Cross-References)

• Database Relations: Linked databases and properties
• Page References: Internal links and backlinks
• External Links: URLs and integrations
• File Attachments: Document and media references

8. CONTEXTUAL (Metadata & Tags)

• Tags: Custom categorization labels
• Properties: Structured metadata fields
• Templates: Reusable page structures
• Workspace Context: Team and project associations

Implementation Architecture

MCP Layer (Protocol)

• NotionMCPAdapter: Implements MCP protocol for Notion
• Authentication: Token management and refresh
• Rate Limiting: Respect Notion API limits (3 requests/second)
• Error Handling: Graceful degradation and retry logic

Spatial Layer (Cognitive)

• NotionSpatialMapper: Converts Notion entities to spatial positions
• Position Mapping: Integer-based spatial coordinates
• Context Preservation: Maintains Notion metadata in spatial context
• Relationship Tracking: Maps Notion links to spatial connections

Domain Integration

• NotionDocumentService: High-level document operations
• NotionTaskService: Task and workflow management
• NotionMeetingService: Meeting notes and action items
• NotionRoadmapService: Project planning and milestones

Rate Limiting & Pagination

API Constraints

• Rate Limit: 3 requests per second
• Pagination: 100 items per page maximum
• Search Limits: 100 results per search query
• Database Queries: 100 items per filter operation

Implementation Strategy

• Request Queuing: Implement rate limit compliance
• Batch Operations: Group related API calls
• Caching: Cache frequently accessed data
• Incremental Sync: Only fetch changed content

Testing Strategy

TDD Approach

1. Connection Tests: Verify authentication and basic connectivity
2. Spatial Mapping Tests: Validate Notion → Spatial conversion
3. Integration Tests: End-to-end workflow validation
4. Performance Tests: Rate limiting and pagination handling

Test Data Requirements

• Test Workspace: Dedicated Notion workspace for testing
• Sample Databases: Product requirements, tasks, meetings
• Mock Data: Synthetic content for edge case testing
• Integration Tokens: Separate tokens for test vs production

Success Criteria

Phase 1: Foundation (Week 1)

• NotionMCPAdapter basic structure
• Authentication flow implementation
• Basic spatial mapping framework
• Connection and health check tests

Phase 2: Core Functionality (Week 2)

• Database and page retrieval
• Spatial position mapping
• Content type recognition
• Basic CRUD operations

Phase 3: Advanced Features (Week 3)

• Relationship mapping
• Workflow state tracking
• Search and filtering
• Performance optimization

Phase 4: Integration (Week 4)

• Domain service integration
• End-to-end workflow testing
• Production deployment
• Documentation and handoff

Risk Assessment

Technical Risks

• API Changes: Notion API evolution may break integration
• Rate Limiting: Complex workflows may hit API limits
• Data Consistency: Large databases may have sync delays
• Authentication: Token expiration and refresh complexity

Mitigation Strategies

• Version Pinning: Lock to stable API versions
• Graceful Degradation: Handle API failures gracefully
• Incremental Sync: Minimize data transfer requirements
• Monitoring: Implement comprehensive error tracking

Rollback Plan

Immediate Rollback

• Feature Flags: Disable Notion integration without code changes
• Fallback Services: Redirect to existing document management
• Data Preservation: Maintain spatial mappings for future restoration

Long-term Recovery

• Data Export: Extract Notion data to alternative formats
• Migration Tools: Convert to other document systems
• Documentation: Preserve integration knowledge for future attempts

Next Steps

1. Immediate: Begin NotionMCPAdapter shell implementation
2. This Week: Complete authentication and basic connection framework
3. Next Week: Implement spatial mapping and core CRUD operations
4. Following Week: Advanced features and domain integration
5. Final Week: Testing, deployment, and documentation
