create_phone_qr

Instructions

Implementation Reference

• packages/mcp/src/tools.ts:464-470 (handler)

  Handler function for create_phone_qr that extracts phone_number and calls the API route /api/qr with type 'phone' and phone_data.

  handler: async (input: Record<string, unknown>) => {
    const { phone_number, ...rest } = input;
    return apiRequest("/api/qr", {
      method: "POST",
      body: { type: "phone", phone_data: { phone_number }, ...rest },
    });
  },

• packages/mcp/src/tools.ts:450-463 (schema)

  Input schema for create_phone_qr using Zod. Required: phone_number. Optional: label, format, foreground_color, background_color, dot_style, corner_style, logo_url, frame_style, frame_text, frame_color, frame_text_color.

  inputSchema: z.object({
    phone_number: z.string().describe("Phone number to call."),
    label: z.string().optional().describe("Label for this QR code."),
    format: z.enum(["svg", "png"]).default("svg").describe("Image format."),
    foreground_color: z.string().regex(/^#[0-9A-Fa-f]{6}$/).optional().describe("Hex color for dots."),
    background_color: z.string().regex(/^#[0-9A-Fa-f]{6}$/).optional().describe("Hex color for background."),
    dot_style: z.enum(["square", "rounded", "dots", "classy-rounded"]).optional().describe("Dot shape."),
    corner_style: z.enum(["square", "extra-rounded", "dot"]).optional().describe("Corner shape."),
    logo_url: z.string().optional().describe("Logo URL or data URI."),
    frame_style: z.enum(["none", "banner_bottom", "banner_top", "rounded"]).optional().describe("Frame style around QR."),
    frame_text: z.string().max(30).optional().describe("CTA text on frame (max 30 chars)."),
    frame_color: z.string().regex(/^#[0-9A-Fa-f]{6}$/).optional().describe("Frame background color."),
    frame_text_color: z.string().regex(/^#[0-9A-Fa-f]{6}$/).optional().describe("Frame text color."),
  }),

• packages/mcp/src/server.ts:21-53 (registration)

  Registration loop that registers all tools (including create_phone_qr) with the MCP server via server.tool().

  for (const [name, tool] of Object.entries(tools)) {
    server.tool(
      name,
      tool.description,
      tool.inputSchema.shape,
      async (input: Record<string, unknown>) => {
        try {
          const result = await tool.handler(input as any);
          return {
            content: [
              {
                type: "text" as const,
                text: JSON.stringify(result, null, 2),
              },
            ],
          };
        } catch (error) {
          const message = error instanceof Error ? error.message : String(error);
          return {
            content: [
              {
                type: "text" as const,
                text: JSON.stringify({
                  error: message,
                  hint: "Check the input parameters and try again. Use list_qr_codes to verify available QR codes.",
                }),
              },
            ],
            isError: true,
          };
        }
      }
    );

• packages/mcp/src/api-client.ts:13-40 (helper)

  The apiRequest helper function used by create_phone_qr's handler to make HTTP POST requests to the backend API.

  export async function apiRequest(path: string, options: RequestOptions = {}) {
    const { method = "GET", body, query } = options;
  
    let url = `${BASE_URL}${path}`;
    if (query) {
      const params = new URLSearchParams();
      for (const [key, value] of Object.entries(query)) {
        params.set(key, String(value));
      }
      url += `?${params.toString()}`;
    }
  
    const headers: Record<string, string> = {
      "X-API-Key": API_KEY,
    };
  
    if (body) {
      headers["Content-Type"] = "application/json";
    }
  
    const res = await fetch(url, {
      method,
      headers,
      body: body ? JSON.stringify(body) : undefined,
    });
  
    return res.json();
  }
