create-page

Implementation Reference

• src/lib/mcp-server.ts:228-279 (handler)

  MCP tool registration for 'create-page', defining the input schema with Zod, the handler function that processes parameters, calls NotionService.createPage, and returns the result or formatted error.

  this.server.tool(
    "create-page",
    {
      parent_type: z
        .enum(["database_id", "page_id"])
        .describe("Type of parent (database or page)"),
      parent_id: z.string().describe("ID of the parent database or page"),
      properties: z.string().describe("JSON string of page properties"),
      children: z
        .string()
        .optional()
        .describe("JSON string of page content blocks"),
    },
    async ({ parent_type, parent_id, properties, children }) => {
      const params: any = {
        parent: {
          type: parent_type,
          [parent_type]: parent_id,
        },
        properties: JSON.parse(properties),
      };
  
      if (children) {
        params.children = JSON.parse(children);
      }
  
      try {
        const page = await this.notionService.createPage(params);
        return {
          content: [
            {
              type: "text",
              text: JSON.stringify(page, null, 2),
            },
          ],
        };
      } catch (error) {
        console.error("Error in create-page tool:", error);
        return {
          content: [
            {
              type: "text",
              text: `Error: Failed to create page - ${
                (error as Error).message
              }`,
            },
          ],
          isError: true,
        };
      }
    }
  );

• src/lib/notion.ts:148-163 (helper)

  Helper method in NotionService that executes the actual Notion API call to create a page using the client.pages.create method.

  async createPage(params: CreatePage) {
    try {
      return await this.client.pages.create({
        parent:
          params.parent.type === "database_id"
            ? { database_id: params.parent.database_id! }
            : { page_id: params.parent.page_id! },
        properties: params.properties,
        children: params.children,
        icon: params.icon,
        cover: params.cover,
      });
    } catch (error) {
      this.handleError(error);
    }
  }

• src/types/notion.ts:35-47 (schema)

  Zod schema (CreatePageSchema) and TypeScript type (CreatePage) defining the structure for page creation parameters used in NotionService.createPage.

  export const CreatePageSchema = z.object({
    parent: z.object({
      database_id: z.string().optional(),
      page_id: z.string().optional(),
      type: z.enum(["database_id", "page_id"]),
    }),
    properties: z.record(z.any()),
    children: z.array(z.any()).optional(),
    icon: z.any().optional(),
    cover: z.any().optional(),
  });
  
  export type CreatePage = z.infer<typeof CreatePageSchema>;
