Implementation Reference

• src/tools.ts:215-268 (handler)

  Handler for the 'generate_video' tool, constructing the request URL for the Pollinations API.

  export async function handleGenerateVideo(
    args: z.infer<typeof generateVideoSchema>
  ) {
    const model = getModel(args.model);
    if (!model || model.type !== "video") {
      return {
        content: [
          {
            type: "text" as const,
            text: `Unknown video model: ${args.model}. Use list_models to see available models.`,
          },
        ],
        isError: true,
      };
    }
    if (!model.free && !API_KEY) {
      return {
        content: [
          {
            type: "text" as const,
            text: `Model "${args.model}" requires a Pollinations API key. Set POLLINATIONS_API_KEY env variable.`,
          },
        ],
        isError: true,
      };
    }
  
    const params = new URLSearchParams({
      model: args.model,
      aspectRatio: args.aspect_ratio,
      nologo: "true",
    });
    if (args.duration !== undefined) params.set("duration", String(args.duration));
    if (args.seed !== undefined) params.set("seed", String(args.seed));
    if (API_KEY) params.set("token", API_KEY);
  
    const encodedPrompt = encodeURIComponent(args.prompt);
    const url = `https://gen.pollinations.ai/video/${encodedPrompt}?${params}`;
  
    return {
      content: [
        {
          type: "text" as const,
          text: [
            `Video generation started!`,
            `Model: ${model.name}`,
            `Aspect ratio: ${args.aspect_ratio}`,
            `URL: ${url}`,
            `Note: Video generation may take 30-120 seconds. Open the URL in a browser to download.`,
          ].join("\n"),
        },
      ],
    };
  }

• src/tools.ts:66-75 (schema)

  Zod schema definition for 'generate_video' input parameters.

  export const generateVideoSchema = z.object({
    prompt: z.string().describe("Text prompt for video generation"),
    model: z.string().default("grok-video").describe("Model ID (default: grok-video)"),
    aspect_ratio: z
      .enum(["1:1", "16:9", "9:16"])
      .default("1:1")
      .describe("Aspect ratio"),
    duration: z.number().optional().describe("Duration in seconds (model-dependent)"),
    seed: z.number().optional().describe("Seed for reproducibility"),
  });
