Implementation Reference
- index.ts:50-63 (handler)Handler function that fetches active, tradable assets from the Alpaca API based on assetClass, returns JSON or error message.export async function getAssets({ assetClass = 'us_equity' }: { assetClass?: 'us_equity' | 'crypto' }) { try { const data = await request<any[]>({ base: process.env.ALPACA_BROKER_ENDPOINT!, path: "/v1/assets", params: { status: "active", asset_class: assetClass }, }); const assets = data.filter((a: any) => a.tradable); return { content: [{ type: "text", text: JSON.stringify(assets) }] as any }; } catch (err: any) { debug("get-assets error", err); return { content: [{ type: "text", text: `Error fetching assets: ${err.message}` }] as any, isError: true }; } }
- index.ts:132-136 (registration)Registration of the 'get-assets' tool with input schema and handler reference.server.tool( "get-assets", { assetClass: z.enum(["us_equity", "crypto"]).optional().default("us_equity") }, getAssets );
- index.ts:134-134 (schema)Zod input schema for the get-assets tool defining optional assetClass parameter.{ assetClass: z.enum(["us_equity", "crypto"]).optional().default("us_equity") },
- index.ts:20-40 (helper)Reusable request helper function for authenticated API calls to Alpaca, used in getAssets handler.async function request<T>({ base = process.env.ALPACA_ENDPOINT!, path, method = "GET", params = {} }: RequestOptions): Promise<T> { if (!process.env.ALPACA_API_KEY || !process.env.ALPACA_SECRET_KEY) { throw new Error("Alpaca credentials not configured. Set ALPACA_API_KEY and ALPACA_SECRET_KEY."); } const qs = new URLSearchParams(params as Record<string, string>).toString(); const url = `${base}${path}${qs ? `?${qs}` : ""}`; const res = await fetch(url, { method, headers: { "APCA-API-KEY-ID": process.env.ALPACA_API_KEY!, "APCA-API-SECRET-KEY": process.env.ALPACA_SECRET_KEY!, }, }); if (!res.ok) { const err = await res.json(); throw new Error(`${res.status} ${res.statusText} - ${JSON.stringify(err)}`); } return (await res.json()) as T; }
