Implementation Reference
- src/index.ts:401-437 (handler)The handler function for the getOptionStrikes tool. It constructs the API endpoint based on underlying symbol and optional expiration, calls makeAuthenticatedRequest to fetch strikes from TradeStation API, and returns JSON-formatted response or error.
server.tool( "getOptionStrikes", "Get available strike prices for options on an underlying symbol", optionStrikesSchema, async (args) => { try { const { underlying, expiration } = args; let endpoint = `/marketdata/options/strikes/${encodeURIComponent(underlying)}`; if (expiration) { endpoint += `?expiration=${encodeURIComponent(expiration)}`; } const strikes = await makeAuthenticatedRequest(endpoint); return { content: [ { type: "text", text: JSON.stringify(strikes, null, 2) } ] }; } catch (error: unknown) { return { content: [ { type: "text", text: `Failed to fetch option strikes: ${error instanceof Error ? error.message : 'Unknown error'}` } ], isError: true }; } } ); - src/index.ts:96-99 (schema)Zod input schema defining parameters for the getOptionStrikes tool: required 'underlying' symbol and optional 'expiration' date.
const optionStrikesSchema = { underlying: z.string().describe('Underlying symbol (e.g., AAPL, SPY)'), expiration: z.string().optional().describe('Expiration date filter in YYYY-MM-DD format (optional)') }; - src/index.ts:401-437 (registration)MCP server.tool registration for getOptionStrikes, specifying name, description, input schema, and handler function.
