export const estimateGasHandler = async (input: any): Promise<ToolResultSchema> => { try { if (!input.transaction) { return createErrorResponse("Transaction is required"); } const provider = getProvider(); if (!provider) { return createErrorResponse("Provider is required to estimate gas, please set the provider URL"); } const gasEstimate = await provider.estimateGas(input.transaction); return createSuccessResponse( `Gas estimate retrieved successfully Gas estimate: ${gasEstimate.toString()} `); } catch (error) { return createErrorResponse(`Failed to estimate gas: ${(error as Error).message}`); } }; - src/tools.ts:450-469 (schema)The input schema definition for the provider_estimate_gas tool in the tools array.
