Implementation Reference
- src/index.ts:168-179 (handler)The async handler function that executes the 'list_currencies' tool logic. It calls client.getSupportedCurrencies() and returns a formatted string with the count and list of currency codes.
async () => { try { const currencies = await client.getSupportedCurrencies(); return ok( `${currencies.length} currencies supported: ${currencies.join(", ")}`, { count: currencies.length, currencies }, ); } catch (err) { return fail(err); } }, ); - src/index.ts:161-166 (schema)The input schema for 'list_currencies'. No input parameters are required (empty inputSchema object). Includes title, description, and annotations.
{ title: "List supported currencies", description: "Return the list of currency codes supported by the UniRate API (170+ fiat plus major crypto).", inputSchema: {}, annotations: { readOnlyHint: true, openWorldHint: true }, - src/index.ts:159-179 (registration)The tool registration via server.registerTool('list_currencies', ...) which registers the tool name, schema, and handler on the MCP server.
server.registerTool( "list_currencies", { title: "List supported currencies", description: "Return the list of currency codes supported by the UniRate API (170+ fiat plus major crypto).", inputSchema: {}, annotations: { readOnlyHint: true, openWorldHint: true }, }, async () => { try { const currencies = await client.getSupportedCurrencies(); return ok( `${currencies.length} currencies supported: ${currencies.join(", ")}`, { count: currencies.length, currencies }, ); } catch (err) { return fail(err); } }, ); - src/client.ts:182-185 (helper)The client method getSupportedCurrencies() that performs the actual API call to /api/currencies to retrieve the list of supported currency codes.
async getSupportedCurrencies(): Promise<string[]> { const data = await this.request<{ currencies: string[] }>("/api/currencies", {}); return data.currencies; }
