[], null, 2)} `); } catch (error) { return createErrorResponse(`Error getting priority fee estimate: ${error instanceof Error ? error.message : String(error)}`); } } - src/tools.ts:450-466 (schema)The input schema defining the parameters for the tool: accountKeys (array of strings) and optional options (priorityLevel and includeAllPriorityFeeLevels).
