Implementation Reference
- src/tools/chain.ts:13-35 (handler)The execute handler function for the GAS_PRICE tool. Resolves the chain name, instantiates ChainService, fetches gas price, and returns JSON or error.
export const gasPrice = async (args: z.infer<typeof chainParamsSchema>) => { try { const inputChain = args.chain.toLowerCase(); const chainObject = getChainFromName(inputChain); console.error(`[GAS_PRICE] Using chain: ${chainObject} (${chainObject.id})`); const service = new ChainService(); const gasPrice = await service.gasPrice(chainObject.id); if (gasPrice instanceof Error) { return `Error fetching gasPrice: ${gasPrice.message}`; } return JSON.stringify(gasPrice, null, 2); } catch (error: unknown) { const message = error instanceof Error ? error.message : "An unknown error occurred while fetching gasPrice."; console.error(`[GAS_PRICE] Error: ${message}`); throw new Error(`Failed to fetch gasPrice: ${message}`); } }; - src/types.ts:4-12 (schema)Input schema (parameters) for GAS_PRICE tool, defining optional 'chain' parameter defaulting to 'fraxtal'.
export const chainParamsSchema = z.object({ chain: z .string() .optional() .describe( "The blockchain network to execute the transaction on. uses fraxtal as default", ) .default("fraxtal") }); - src/tools/index.ts:22-27 (registration)Registration of the GAS_PRICE tool in the tools export object, linking name, description, parameters, and execute handler.
