Notion MCP Server

Implementation Reference

• src/index.ts:288-321 (handler)

  The handler function that creates a new Notion database under the specified parent page using the Notion client. It takes parentPageId, title, and properties as input and returns success/error messages.

  async ({ parentPageId, title, properties }) => {
    try {
      const response = await notion.databases.create({
        parent: {
          type: "page_id",
          page_id: parentPageId
        },
        title: [
          {
            type: "text",
            text: {
              content: title
            }
          }
        ],
        properties: properties
      });
      
      return {
        content: [{
          type: "text",
          text: `Database created successfully!\nTitle: ${title}\nID: ${response.id}`
        }]
      };
    } catch (error: any) {
      return {
        content: [{
          type: "text",
          text: `Error creating database: ${error.message}`
        }],
        isError: true
      };
    }
  }

• src/index.ts:283-287 (schema)

  Zod schema defining the input parameters for the create-database tool: parentPageId (string), title (string), and properties (record of any).

  { 
    parentPageId: z.string(),
    title: z.string(),
    properties: z.record(z.any())
  },

• src/index.ts:281-322 (registration)

  Registration of the 'create-database' tool on the MCP server using server.tool(), including schema and handler.

  server.tool(
    "create-database",
    { 
      parentPageId: z.string(),
      title: z.string(),
      properties: z.record(z.any())
    },
    async ({ parentPageId, title, properties }) => {
      try {
        const response = await notion.databases.create({
          parent: {
            type: "page_id",
            page_id: parentPageId
          },
          title: [
            {
              type: "text",
              text: {
                content: title
              }
            }
          ],
          properties: properties
        });
        
        return {
          content: [{
            type: "text",
            text: `Database created successfully!\nTitle: ${title}\nID: ${response.id}`
          }]
        };
      } catch (error: any) {
        return {
          content: [{
            type: "text",
            text: `Error creating database: ${error.message}`
          }],
          isError: true
        };
      }
    }
  );
