Architecture

Input Validation

• All tools use Zod schemas for type-safe input validation
• Schemas defined inline with tool handlers
• Runtime validation with helpful error messages

Naming Convention

• All tools follow notion_verb_noun pattern
• Clear, consistent naming for discoverability
• Examples: notion_create_page, notion_query_database, notion_append_block_children

File Structure

src/tools/
├── index.ts          # Barrel export + central routing
├── pages.ts          # Page operations (7 tools)
├── databases.ts      # Database operations (5 tools)
├── blocks.ts         # Block operations (23 tools)
├── users.ts          # User operations (4 tools)
├── comments.ts       # Comment operations (3 tools)
└── search.ts         # Search operations (4 tools)

Each file exports:

• getTools(client: NotionClient): Tool[] - Tool definitions
• handle[Category]Tool(toolName, args, client) - Execution handler

Central Routing

src/tools/index.ts provides:

• getAllTools(client) - Returns all 43 tools
• handleToolCall(toolName, args, client) - Routes to appropriate handler

Notion API Features Covered

Rich Text Support

• All text fields support Notion's rich_text format
• Helper function textToRichText() for simple text conversion
• Supports colors, formatting, links

Property Types

• Full support for all Notion property types
• Database schema creation/updates
• Page property manipulation

Filters & Sorts

• Compound filters (and/or)
• Property filters for all types
• Sorting by property or timestamp

Block Types

• 25+ block types supported
• Nested blocks (children)
• Block-specific properties (color, checkboxes, language, etc.)

Pagination

• Manual pagination tools (start_cursor support)
• Auto-pagination tools (*_all variants)
• Configurable page_size (max 100)

TypeScript Compilation

✅ All files compile successfully with tsc --noEmit ✅ Full type safety with Notion types from src/types/index.ts ✅ No TypeScript errors

Next Steps

To integrate these tools into the server:

1. Import in src/server.ts: import { getAllTools, handleToolCall } from './tools/index.js';
2. Replace inline tools in ListToolsRequestSchema handler with getAllTools(this.client)
3. Replace switch statement in CallToolRequestSchema with handleToolCall(name, args, this.client)
