Implementation Reference
- src/tools.ts:212-224 (handler)The handler function that performs the core logic: sends a POST request to the Novita API endpoint `/gpu/instance/start` with the instance ID and returns the formatted JSON response as tool output.}, async (params) => { const result = await novitaRequest(`/gpu/instance/start`, "POST", { instanceId: params.instanceId, }); return { content: [ { type: "text", text: JSON.stringify(result, null, 2), }, ], }; });
- src/tools.ts:209-211 (schema)Zod input schema defining the required `instanceId` parameter as a string.instanceId: z .string() .describe("ID of the instance to start"),
- src/tools.ts:208-224 (registration)Registers the "start-gpu-instance" tool on the MCP server with its schema and inline handler function.server.tool("start-gpu-instance", { instanceId: z .string() .describe("ID of the instance to start"), }, async (params) => { const result = await novitaRequest(`/gpu/instance/start`, "POST", { instanceId: params.instanceId, }); return { content: [ { type: "text", text: JSON.stringify(result, null, 2), }, ], }; });
- src/utils.ts:15-55 (helper)Supporting utility function that handles authenticated HTTP requests to the Novita AI API, used by the tool handler to start the GPU instance.export async function novitaRequest( endpoint: string, method: string = "GET", body: any = null ) { // Base URL for Novita AI API const API_BASE_URL = "https://api.novita.ai/gpu-instance/openapi/v1"; // Get API key from environment variable const API_KEY = process.env.NOVITA_API_KEY; const url = `${API_BASE_URL}${endpoint}`; const headers = { Authorization: `Bearer ${API_KEY}`, "Content-Type": "application/json", }; const options: any = { method, headers, }; if (body && (method === "POST" || method === "PATCH")) { options.body = JSON.stringify(body); } try { const response = await fetch(url, options); if (!response.ok) { const errorText = await response.text(); throw new Error(`Novita AI API Error: ${response.status} - ${errorText}`); } // Some endpoints might not return JSON const contentType = response.headers.get("content-type"); if (contentType && contentType.includes("application/json")) { return await response.json(); } return { success: true, status: response.status }; } catch (error) { console.error("Error calling Novita AI API:", error); throw error; } }
