+description: Implements Notion API interactions for pages, databases, blocks, users, and search using generated clients and MCP tools. Use when doing ANYTHING that touches Notion workspaces, pages, or databases.
+---
+
+# Major Platform Resource: Notion
+
+## Common: Interacting with Resources
+
+**Security**: Never connect directly to databases/APIs. Never use credentials in code. Always use generated clients or MCP tools.
+
+**Two ways to interact with resources:**
+
+1. **MCP tools** (direct, no code needed): Tools follow the pattern `mcp__resources__<resourcetype>_<toolname>`. Use `mcp__resources__list_resources` to discover available resources and their IDs.
+2. **Generated TypeScript clients** (for app code): Call `mcp__resource-tools__add-resource-client` with a `resourceId` to generate a typed client. Clients are created in `/clients/` (Next.js) or `/src/clients/` (Vite).
+
+**CRITICAL: Do NOT guess client method names or signatures.** The TypeScript clients in `@major-tech/resource-client` have strongly typed inputs and outputs. ALWAYS read the actual client source code in the generated `/clients/` directory (or the package itself) to verify available methods and their exact signatures before writing any client code.
+
+**Framework note**: Next.js = resource clients must be used in server-side code only (Server Components, Server Actions, API Routes). Vite = call directly from frontend.
+
+**Error handling**: Always check `result.ok` before accessing `result.result`.
+
+**Invocation keys must be static strings** — use descriptive literals like `"fetch-user-orders"`, never dynamic values like `` `${date}-records` ``.

+
+## MCP Tools
+
+- `mcp__resources__notion_search` — Search pages and databases in the Notion workspace. Args: `resourceId`, `query`, `filter?`, `sort?`, `startCursor?`, `pageSize?`
+- `mcp__resources__notion_get_page` — Get a Notion page by ID. Args: `resourceId`, `pageId`
+- `mcp__resources__notion_query_database` — Query a Notion database with optional filters and sorts. Args: `resourceId`, `databaseId`, `filter?`, `sorts?`, `startCursor?`, `pageSize?`
+- `mcp__resources__notion_get_database` — Get a Notion database schema and properties. Args: `resourceId`, `databaseId`
+- `mcp__resources__notion_get_block_children` — Get child blocks of a page or block. Args: `resourceId`, `blockId`, `startCursor?`, `pageSize?`
+- `mcp__resources__notion_invoke` — Make any HTTP request to the Notion API. Args: `resourceId`, `method`, `path`, `query?`, `body?`, `timeoutMs?`
+
+## TypeScript Client
+
+```typescript
+import { notionClient } from "./clients";
+
+// Generic invoke for any Notion API endpoint
+const result = await notionClient.invoke("GET", "/v1/pages/PAGE_ID", "get-page");
+if (result.ok && result.result.status === 200 && result.result.body.kind === "json") {
+	const page = result.result.body.value;
+}
+
+// POST with body
+const searchResult = await notionClient.invoke("POST", "/v1/search", "search-pages", {
+	body: { type: "json", value: { query: "Meeting notes" } },
+});
+
+// Query a database with filters
+const queryResult = await notionClient.invoke("POST", "/v1/databases/DB_ID/query", "query-tasks", {
+	body: {
+		type: "json",
+		value: {
+			filter: { property: "Status", select: { equals: "Done" } },
+			sorts: [{ property: "Created", direction: "descending" }],
+		},
+	},
+});
+```
+
+## Tips
+
+- All Notion API requests automatically include the `Notion-Version: 2022-06-28` header
+- Notion uses UUIDs for page/database/block IDs (with or without hyphens)
+- Pagination uses `start_cursor` and `has_more` pattern
+- Database queries use a filter object — refer to Notion API docs for filter syntax
+- Rich text is returned as arrays of rich text objects, not plain strings
+- **Rate limit**: ~3 requests/second per integration. Handle HTTP 429 with Retry-After header.
+- Response structure: `{ kind: "api", status: number, body: { kind: "json", value: {...} } }`
