Implementation Reference
- src/actions.ts:33-35 (handler)The actual handler function that executes the tool logic. Calls the DolarApi client's GET /v1/cotizaciones endpoint to fetch all foreign currency exchange rates vs ARS.
export async function getAllCurrencies(client: DolarApiClient): Promise<unknown> { return client.get<CurrencyRate[]>("/v1/cotizaciones"); } - src/schemas.ts:1-19 (schema)Schema definitions for tool parameters. get_all_currencies has no input params (empty object {}), so no specific schema is defined for it.
export interface GetDollarParams { type: string; } export interface GetCurrencyParams { currency: string; } export interface ConvertParams { amount: number; from: string; to?: string; use_buy?: boolean; } export interface GetSpreadParams { type_a: string; type_b: string; } - src/mcp-server.ts:45-58 (registration)MCP server registration of the 'get_all_currencies' tool. Defines its description, empty input schema, and the async handler that calls tools.get_all_currencies().
server.tool( "get_all_currencies", "Get all foreign currency exchange rates vs ARS (EUR, BRL, UYU, CLP, etc.).", {}, async () => { try { const result = await tools.get_all_currencies(); return { content: [{ type: "text", text: JSON.stringify(result, null, 2) }] }; } catch (error) { const message = error instanceof Error ? error.message : String(error); return { content: [{ type: "text", text: message }], isError: true }; } }, ); - src/index.ts:17-30 (helper)The createDolarTools() function that wires the getAllCurrencies action to the 'get_all_currencies' tool name by passing a client instance.
export function createDolarTools() { const client = new DolarApiClient(); return { tools: { get_all_dollars: () => getAllDollars(client), get_dollar: (params: GetDollarParams) => getDollar(client, params), get_all_currencies: () => getAllCurrencies(client), get_currency: (params: GetCurrencyParams) => getCurrency(client, params), convert: (params: ConvertParams) => convert(client, params), get_spread: (params: GetSpreadParams) => getSpread(client, params), }, }; } - src/client.ts:1-16 (helper)The DolarApiClient class used by the handler to make HTTP GET requests to https://dolarapi.com/v1/cotizaciones.
const BASE_URL = "https://dolarapi.com"; export class DolarApiClient { async get<T = unknown>(path: string): Promise<T> { const res = await fetch(`${BASE_URL}${path}`, { method: "GET", headers: { "Content-Type": "application/json" }, signal: AbortSignal.timeout(15000), }); if (!res.ok) { const body = await res.text(); throw new Error(`GET ${path} failed (${res.status}): ${body}`); } return res.json() as Promise<T>; } }
