Update a product

Instructions

Implementation Reference

• src/tools/products.ts:120-122 (handler)

  The handler function for deonpay_update_product. It destructures `id` from args for the URL path and calls `client.patch()` on `/products/{id}` with the remaining fields compacted (stripping empty/undefined values).

  safeHandler(async ({ id, ...rest }) => {
    return client.patch(`/products/${encodeURIComponent(id)}`, compact(rest));
  }),

• src/tools/products.ts:106-118 (schema)

  Zod input schema for deonpay_update_product. Requires `id` (UUID or SKU string), with optional fields: name, description, unit_amount (min 100 centavos), currency, image_url, sku, is_active, stock_tracking, stock_quantity, and metadata.

  inputSchema: {
    id: z.string().min(1).describe("Product UUID or SKU."),
    name: z.string().min(1).max(255).optional(),
    description: z.string().max(1000).optional(),
    unit_amount: z.number().int().min(100).optional().describe("New unit price in centavos."),
    currency: z.string().length(3).optional(),
    image_url: z.string().url().optional(),
    sku: z.string().max(100).optional(),
    is_active: z.boolean().optional(),
    stock_tracking: z.boolean().optional(),
    stock_quantity: z.number().int().min(0).optional(),
    metadata: z.record(z.unknown()).optional(),
  },

• src/tools/products.ts:100-123 (registration)

  Registration of the tool named 'deonpay_update_product' on the MCP server via `server.registerTool()`, including its title, description, input schema, and handler.

  server.registerTool(
    "deonpay_update_product",
    {
      title: "Update a product",
      description:
        "Update an existing product (resolved by UUID or SKU). Only fields you send are changed. Use this for price adjustments, renaming, toggling is_active, updating stock_quantity, or swapping the image_url. Note: under the hood the API uses HTTP PATCH (not PUT).",
      inputSchema: {
        id: z.string().min(1).describe("Product UUID or SKU."),
        name: z.string().min(1).max(255).optional(),
        description: z.string().max(1000).optional(),
        unit_amount: z.number().int().min(100).optional().describe("New unit price in centavos."),
        currency: z.string().length(3).optional(),
        image_url: z.string().url().optional(),
        sku: z.string().max(100).optional(),
        is_active: z.boolean().optional(),
        stock_tracking: z.boolean().optional(),
        stock_quantity: z.number().int().min(0).optional(),
        metadata: z.record(z.unknown()).optional(),
      },
    },
    safeHandler(async ({ id, ...rest }) => {
      return client.patch(`/products/${encodeURIComponent(id)}`, compact(rest));
    }),
  );

• src/tools/index.ts:24-24 (registration)

  The tool is registered as part of the module, called via `registerProductTools(server, client)` in the central `registerAllTools` registry function.

  registerProductTools(server, client);

• src/tools/_helpers.ts:83-91 (helper)

  The `compact` helper used by the handler to strip undefined/null/empty-string values before sending the PATCH body.

  export function compact<T extends Record<string, unknown>>(obj: T): Partial<T> {
    const out: Record<string, unknown> = {};
    for (const [key, value] of Object.entries(obj)) {
      if (value === undefined || value === null) continue;
      if (typeof value === "string" && value.trim() === "") continue;
      out[key] = value;
    }
    return out as Partial<T>;
  }
