update_page

Instructions

Implementation Reference

• src/index.js:161-179 (handler)

  MCP tool handler for 'update_page' that extracts input, validates, calls the updatePage helper, and returns success indicator.

  async (input) => {
    // Handler
    const { pageId, ...updateData } = input;
    // Basic validation, although schema handles optionality
    if (Object.keys(updateData).length === 0) {
      throw new Error(
        "No update data provided (title, status, content, or elementor_data)."
      );
    }
    await updatePage(pageId, updateData);
    return {
      content: [
        {
          type: "text",
          text: "true",
        },
      ],
    };
  }

• src/index.js:138-160 (schema)

  Zod input schema defining parameters for the update_page tool: pageId (required), title/status/content/elementor_data (optional).

  {
    // Input Schema: Use plain object with Zod types
    pageId: z
      .number()
      .int()
      .positive()
      .describe("The ID of the page to update."),
    title: z.string().optional().describe("The title for the page."),
    status: z
      .enum(["publish", "future", "draft", "pending", "private"])
      .optional()
      .describe("The status for the page (e.g., 'publish', 'draft')."),
    content: z
      .string()
      .optional()
      .describe("The standard WordPress content for the page (optional)."),
    elementor_data: z
      .string()
      .optional()
      .describe(
        "The Elementor page data as a JSON string. Optional for update."
      ),
  },

• src/index.js:135-180 (registration)

  Registration of the 'update_page' tool on the MCP server using server.tool() with name, description, schema, and handler.

  server.tool(
    "update_page",
    "Updates an existing page in WordPress with Elementor data, it will return a boolean value to indicate if the update was successful.",
    {
      // Input Schema: Use plain object with Zod types
      pageId: z
        .number()
        .int()
        .positive()
        .describe("The ID of the page to update."),
      title: z.string().optional().describe("The title for the page."),
      status: z
        .enum(["publish", "future", "draft", "pending", "private"])
        .optional()
        .describe("The status for the page (e.g., 'publish', 'draft')."),
      content: z
        .string()
        .optional()
        .describe("The standard WordPress content for the page (optional)."),
      elementor_data: z
        .string()
        .optional()
        .describe(
          "The Elementor page data as a JSON string. Optional for update."
        ),
    },
    async (input) => {
      // Handler
      const { pageId, ...updateData } = input;
      // Basic validation, although schema handles optionality
      if (Object.keys(updateData).length === 0) {
        throw new Error(
          "No update data provided (title, status, content, or elementor_data)."
        );
      }
      await updatePage(pageId, updateData);
      return {
        content: [
          {
            type: "text",
            text: "true",
          },
        ],
      };
    }
  );

• src/wp-api.js:41-68 (helper)

  Core helper function updatePage that constructs the payload from input data, validates elementor_data, and performs the PUT-like update via WordPress REST API POST to /pages/{id}.

  async function updatePage(pageId, pageData) {
      const client = getApiClient();
  
      const payload = {};
      if (pageData.title) payload.title = pageData.title;
      if (pageData.status) payload.status = pageData.status;
      if (pageData.content) payload.content = pageData.content; // Use !== undefined to allow setting empty content
  
      if (pageData.elementor_data) {
          if (typeof pageData.elementor_data !== 'string') {
               throw new Error('elementor_data must be provided as a JSON string.');
          }
           try {
              JSON.parse(pageData.elementor_data); // Basic validation
          } catch (e) {
              throw new Error('elementor_data is not valid JSON string.');
          }
          payload.meta = { _elementor_data: pageData.elementor_data };
      }
  
      if (Object.keys(payload).length === 0) {
          throw new Error("No update data provided.");
      }
  
      // WP uses POST for updates via ID route
      const response = await client.post(`/wp-json/wp/v2/pages/${pageId}`, payload);
      return response.data;
  }
