{
  "mcpServers": {
    "notion": {

Code Architecture

The codebase follows strict project standards with 4 clearly delineated sections in index.mjs:

1. Import Section: Module dependencies (@modelcontextprotocol/sdk, @notionhq/client, zod, dotenv).
2. Functions Section: Low-level Notion API operations.
3. Handler Section: MCP tool definitions and stdio server initialization.
4. Comments Section: Exhaustive documentation for LLM code comprehension and testing.
