Implementation Reference
- src/index.ts:769-790 (handler)The handler function for the 'extract-video' tool. It proxies the request to an external API endpoint at `${NWS_API_BASE}/api/v1/extract-video`, passing inputMethod, video URL/base64, prompt, and jsonMode. Returns the API response as text content.async ({ inputMethod, video, prompt, jsonMode }) => { const apiKey = process.env.DUMPLING_API_KEY; if (!apiKey) throw new Error("DUMPLING_API_KEY not set"); const response = await fetch(`${NWS_API_BASE}/api/v1/extract-video`, { method: "POST", headers: { "Content-Type": "application/json", Authorization: `Bearer ${apiKey}`, }, body: JSON.stringify({ inputMethod, video, prompt, jsonMode, requestSource: "mcp", }), }); if (!response.ok) throw new Error(`Failed: ${response.status} ${await response.text()}`); const data = await response.json(); return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] }; }
- src/index.ts:763-768 (schema)Input schema validation for the 'extract-video' tool using Zod schemas for parameters: inputMethod (url/base64), video (string), prompt (string), jsonMode (optional boolean).{ inputMethod: z.enum(["url", "base64"]).describe("Input method"), video: z.string().describe("URL or base64-encoded video"), prompt: z.string().describe("Extraction prompt"), jsonMode: z.boolean().optional().describe("Return in JSON format"), },
- src/index.ts:760-791 (registration)Registration of the 'extract-video' tool on the MCP server using server.tool(), including name, description, input schema, and inline handler function.server.tool( "extract-video", "Extract structured data from videos based on a prompt.", { inputMethod: z.enum(["url", "base64"]).describe("Input method"), video: z.string().describe("URL or base64-encoded video"), prompt: z.string().describe("Extraction prompt"), jsonMode: z.boolean().optional().describe("Return in JSON format"), }, async ({ inputMethod, video, prompt, jsonMode }) => { const apiKey = process.env.DUMPLING_API_KEY; if (!apiKey) throw new Error("DUMPLING_API_KEY not set"); const response = await fetch(`${NWS_API_BASE}/api/v1/extract-video`, { method: "POST", headers: { "Content-Type": "application/json", Authorization: `Bearer ${apiKey}`, }, body: JSON.stringify({ inputMethod, video, prompt, jsonMode, requestSource: "mcp", }), }); if (!response.ok) throw new Error(`Failed: ${response.status} ${await response.text()}`); const data = await response.json(); return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] }; } );
