Implementation Reference
- src/index.ts:1127-1128 (handler)Handler logic for the retell_get_call tool. Makes a GET request to the Retell API endpoint `/v2/get-call/{call_id}` using the provided call_id argument.case "retell_get_call": return retellRequest(`/v2/get-call/${args.call_id}`, "GET");
- src/index.ts:114-127 (schema)Input schema definition for the retell_get_call tool, specifying that a 'call_id' string parameter is required.{ name: "retell_get_call", description: "Retrieve details of a specific call including transcript, recording URL, duration, and analysis.", inputSchema: { type: "object", properties: { call_id: { type: "string", description: "The unique identifier of the call to retrieve" } }, required: ["call_id"] } },
- src/index.ts:1283-1285 (registration)Registration of the tool list handler, which returns the array of tools including the schema for retell_get_call.server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools }; });
- src/index.ts:1287-1313 (registration)Registration of the tool execution handler, which dispatches to executeTool based on the tool name 'retell_get_call'.// Register tool execution handler server.setRequestHandler(CallToolRequestSchema, async (request) => { const { name, arguments: args } = request.params; try { const result = await executeTool(name, args as Record<string, unknown>); return { content: [ { type: "text", text: JSON.stringify(result, null, 2), }, ], }; } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error); return { content: [ { type: "text", text: `Error: ${errorMessage}`, }, ], isError: true, }; } });
- src/index.ts:23-57 (helper)Helper function used by the retell_get_call handler to make authenticated HTTP requests to the Retell AI API.async function retellRequest( endpoint: string, method: string = "GET", body?: Record<string, unknown> ): Promise<unknown> { const apiKey = getApiKey(); const headers: Record<string, string> = { "Authorization": `Bearer ${apiKey}`, "Content-Type": "application/json", }; const options: RequestInit = { method, headers, }; if (body && method !== "GET") { options.body = JSON.stringify(body); } const response = await fetch(`${RETELL_API_BASE}${endpoint}`, options); if (!response.ok) { const errorText = await response.text(); throw new Error(`Retell API error (${response.status}): ${errorText}`); } // Handle 204 No Content if (response.status === 204) { return { success: true }; } return response.json(); }
